Question 1

How Does the Pet Food Case Packaging Line Seamlessly Connect with the Upstream Production Line?

Accepted Answer

Seamless integration between the upstream pet food bagging machine and the downstream case packaging line is fundamental to achieving high Overall Equipment Effectiveness (OEE) and preventing costly bottlenecks. At TECHFLOW PACKAGING SOLUTIONS, we approach this integration challenge by first analyzing the client's existing production environment and infeed conditions, which generally fall into two categories: ordered infeed and bulk buffer infeed.

In an ordered infeed scenario, the pet food sachets exit the primary packaging machine—such as a multi-lane VFFS or a high-speed flow wrapper—in a relatively organized, single-file or multi-lane stream with consistent orientation and spacing. In this configuration, the connection is achieved through a belt conveyor system (modular plastic belt conveyor or PU belt conveyor) that bridges the gap between the bagging machine's discharge point and the sorting machine's silo (infeed hopper or accumulation silo). The conveyor speed is synchronized with the upstream machine via encoder feedback or PLC handshake signals, ensuring that sachets arrive at the sorter at a steady, non-overlapping rate. Adjustable side rails and pneumatic guide rails on the conveyor accommodate sachet width variations, while a buffer zone on the conveyor absorbs minor speed fluctuations without causing pile-ups.

In the second scenario—bulk buffer infeed—the upstream production process may involve manual packing into temporary storage bins, or the sachets may be collected in a buffer silo (accumulation hopper) due to batch processing or semi-automatic upstream operations. Here, operators manually transfer the sachets from the temporary storage containers into the sorting machine's silo. To facilitate this, TECHFLOW PACK designs the silo with a large-capacity infeed hopper, low-friction stainless-steel surfaces, and vibratory or belt-driven discharge mechanisms that gently meter the bulk sachets into the sorting rollers. The silo is equipped with level sensors that alert operators when the supply is running low, preventing starvation of the line.

Regardless of the infeed method, seamless integration requires line synchronization at the control system level. The master PLC of the pet food case packaging line communicates with the upstream bagging machine's controller via industrial Ethernet protocols such as Profinet or EtherNet/IP. This communication enables speed matching, emergency stop chaining, and production data exchange. For example, if the case packer experiences a jam and stops, the upstream conveyor automatically decelerates or diverts product into an accumulation loop to prevent backup. TECHFLOW PACK specializes in designing these turnkey pet food packaging lines with plug-and-play integration, minimizing the mechanical and electrical interface risks that often plague multi-vendor installations.

Question 2

What Essential Equipment Does a Fully Automatic Pet Food Sachet Case Packaging Line Include?

Accepted Answer

A fully automatic pet food sachet case packaging line is a sophisticated, multi-station end of line packaging system designed to transform individually wrapped pet food sachets from the primary packaging stage into shelf-ready, palletized cases with minimal human intervention. At TECHFLOW PACKAGING SOLUTIONS, we engineer these lines as integrated, modular systems where each component is precisely synchronized to handle the unique challenges of flexible pet food packaging—including lightweight sachets, varying film coefficients of friction, and strict hygiene requirements. The essential equipment chain typically begins with the upstream primary packaging machine, most commonly a Vertical Form Fill Seal (VFFS) machine or a Horizontal Form Fill Seal (HFFS) flow wrapper, which produces the sealed pet food sachets containing wet food, treats, or nutritional supplements.

Immediately following the bagging machine, a transition conveyor (also called a transfer conveyor or interconnecting belt) receives the sachets and transports them away from the sealing jaws while allowing them to cool and stabilize. This conveyor often incorporates cooling fans or accumulation buffers to prevent heat-induced seal distortion. The sachets then enter a sorting machine (sachet sorting unit), which is arguably the most critical upstream component for secondary packaging. Because sachets exiting a VFFS are often overlapping, skewed, or delivered in a disorganized mass, the sorting machine uses multi-row roller conveyors with differential speeds and arrays of photoelectric sensors to singulate, flatten, and align each sachet into a single-file, uniformly spaced stream.

Downstream of the sorter, a counting machine (electronic counting unit) verifies that the correct number of sachets passes through before they enter the collation zone. This counting function can be integrated into the sorting module or operate as a standalone unit with high-speed optical sensors. The counted sachets are then fed into a servo collation system (servo-driven grouping station), where they are arranged into the required pack pattern—such as 4×3, 5×4, or 6×5 matrices—matching the case dimensions. For wraparound case packing applications, this collation is often performed by a dual-servo indexing system that creates tight, uniform bundles.

The collated group then proceeds to the case packer machine, which may be a pick-and-place robotic case packer for RSC (Regular Slotted Container) cartons or a wraparound case packer for glued wraparound cartons. Finally, the sealed cases pass through a checkweigher (in-line weight inspection system) to verify pack count accuracy, followed by a reject station that diverts underweight or overweight cases, and ultimately a case conveyor leading to palletizing. At TECHFLOW PACK, we customize each of these modules—sorting, counting, collating, and case packing—to match the client's sachet dimensions, production speed targets, and factory layout constraints, ensuring a seamless pet food packaging automation solution.

Question 3

What Essential Equipment Does a Yogurt Cup End-of-Line Packaging Line Include?

Accepted Answer

A yogurt cups end-of-line packaging line represents a highly integrated segment of dairy packaging automation, bridging the gap between primary cup forming/filling and palletized distribution. At TECHFLOW PACKAGING SOLUTIONS, we design these lines as complete turnkey packaging systems that ensure delicate dairy products move from the filling machine to the shipping dock with maximum efficiency, hygiene compliance, and product integrity. The core equipment chain begins with the transition conveyor system (also called an interconnecting conveyor or transfer belt), which receives the sealed yogurt cups directly from the cup filling and sealing machine. This conveyor is typically constructed from food-grade stainless steel with modular plastic belts or PU belts, featuring adjustable side rails and drip trays to accommodate cup diameters ranging from 75mm to 95mm and to manage condensation or product residue common in chilled dairy environments.

Following the transition conveyor, the line incorporates a vision inspection station equipped with high-resolution industrial cameras and LED strobe lighting. This system performs critical quality control functions—detecting improperly sealed cups, underfilled containers, damaged rims, or missing lids—before the cups enter the packaging phase. Rejected cups are pneumatically diverted to a waste chute, ensuring only perfect products proceed downstream. Next comes the cup collation and alignment system (cup arranging mechanism), which uses precision servo-driven lane dividers and timing screws to organize the randomly spaced cups into parallel lanes with exact center-to-center spacing. This alignment is crucial for downstream robotic handling.

The heart of the line is the wraparound case packer (also known as a wraparound cartoning machine or one-piece case former), which automatically erects flat corrugated blanks into open trays, receives the collated cup matrix, wraps the carton around the product bundle, and seals the flaps using a hot-melt glue system. Supporting this core machine is a delta robot picking system (spider robot or parallel kinematic robot) that gently transfers cups from the alignment conveyor into the collation buffer station. Downstream of the case packer, an in-line checkweigher (dynamic weighing system) verifies that each sealed case contains the correct number of cups by detecting weight deviations as small as ±2 grams. Non-conforming cases are rejected by a pneumatic pusher or drop-down conveyor segment.

Finally, the line includes a case coding and marking system, typically an inkjet printer or laser coder, that applies batch numbers, expiration dates, barcodes, and traceability information directly onto the exterior of the case. Additional auxiliary equipment may include accumulation buffers, carton blank magazines with low-level sensors, glue melters with temperature control, and conveyors leading to palletizing. At TECHFLOW PACK, we integrate all these components under a single master PLC architecture with centralized HMI control, ensuring that the yogurt cups packaging line operates as a unified, synchronized system rather than a collection of standalone machines.

Question 6

Is a Remote Control Module Essential for a Wet Wipes Case Packer?

Accepted Answer

Yes, in today's connected manufacturing environment, a remote control module (also referred to as a remote access module, remote diagnostics system, or IoT connectivity module) is not merely a convenient add-on—it is an essential feature that every modern automatic wet wipes case packing machine should possess. At TECHFLOW PACK, we integrate remote access capabilities as a standard feature across our case packing machine portfolio because we recognize that minimizing downtime and resolving technical issues rapidly are paramount to our clients' profitability.

A remote control module enables secure, encrypted communication between the case packer's PLC (Programmable Logic Controller) and the manufacturer's technical support center via the internet. When a programming error, sensor misalignment, servo alarm, or software bug occurs, the machine operator or plant engineer can grant temporary remote access to TECHFLOW PACKAGING SOLUTIONS's support team. Our technicians can then log into the machine's control system in real time, view the HMI screen, diagnose the fault, adjust parameters, update PLC logic, or even commission new product formats—all without traveling to the client's site. This capability reduces mean time to repair (MTTR) from days or weeks to hours or even minutes.

Beyond reactive troubleshooting, remote control modules enable predictive maintenance and continuous performance optimization. The module can continuously log operational data such as cycle counts, vacuum levels, servo motor temperatures, and error frequencies to a cloud-based dashboard. TECHFLOW PACK's engineers can analyze these data trends to identify wear patterns before they cause failures, recommend preventive maintenance schedules, and suggest parameter adjustments to improve throughput. For example, if data shows that vacuum pressure is gradually declining on a gripper zone, our team can alert the client to inspect the foam pad or vacuum filter before a dropped-pack incident occurs.

For international clients—particularly those in the Middle East, Southeast Asia, Eastern Europe, and North America where TECHFLOWPACK has an established export presence—the remote control module eliminates the dependency on local service availability and reduces the total cost of ownership. Instead of waiting for a technician to obtain a visa, book flights, and arrive on-site, most software-related issues can be resolved immediately. Furthermore, the remote module facilitates remote Factory Acceptance Testing (FAT) and virtual commissioning, allowing clients to witness machine performance and sign off on acceptance criteria from their home office before shipment.

In the context of Industry 4.0 and smart factory initiatives, remote connectivity also enables integration with higher-level Manufacturing Execution Systems (MES) and Enterprise Resource Planning (ERP) platforms. The wet wipes case packer can report real-time production counts, downtime events, and quality data directly to the plant's central system, supporting traceability requirements and automated reporting. Given these compelling benefits—faster fault resolution, predictive maintenance, lower service costs, and Industry 4.0 readiness—a remote control module is absolutely indispensable when purchasing a fully automatic wet wipes case packing machine from a leading manufacturer like TECHFLOW PACKAGING SOLUTIONS.

Question 7

What Are the Advantages of Using a Full-Surface Sponge Vacuum Pad Gripper on a Wet Wipes Case Packer?

Accepted Answer

Adopting a full-surface sponge vacuum pad gripper design on a wet wipes case packer delivers transformative benefits in terms of format flexibility, operational stability, and product protection. At TECHFLOW PACK, we have integrated full-surface sponge vacuum technology into many of our automatic case packer machines after observing its superior performance across diverse wet wipe product ranges, from small alcohol wipes to large baby wipe packs.

The first and most significant advantage is multi-format compatibility without tool changeover. Traditional gripper systems that rely on arrays of discrete suction cups are often dimensioned for a specific pack size and pattern. When a manufacturer needs to switch from 5 packs per row to 8 packs per row, the entire gripper plate typically must be replaced or repositioned—a process that can take 30 to 60 minutes and requires skilled technicians. In contrast, a full-surface sponge vacuum pad covers a broad active area. As long as the pack group falls within the sponge footprint, the gripper can handle it without any physical modification. This means operators can switch between SKUs directly from the HMI touch screen, dramatically reducing changeover time and increasing productive uptime. For wet wipes packaging lines that run multiple product variants daily, this flexibility translates directly into higher Overall Equipment Effectiveness (OEE) and lower labor costs.

The second advantage is exceptional holding stability and zero dropped packs. Wet wipe packs are notoriously difficult to grip because their laminated film surfaces can be slightly oily, wrinkled, or porous. Discrete suction cups can lose vacuum on individual packs, causing partial drops that contaminate the machine and waste product. A full-surface foam pad, however, maintains vacuum across the entire contact area. Even if one section of the foam encounters a minor leak, the surrounding material compensates, preserving sufficient holding force to transport the complete pack matrix safely to the carton. This reliability is especially critical during high-speed operations where the robot may accelerate at rates exceeding 3 m/s².

The third advantage is superior product protection during the packing cycle. Wet wipe packs are filled with liquid solution and sealed under slight vacuum or nitrogen flush. Excessive compression force applied by rigid grippers can rupture the seal, causing leakage that damages the carton and creates a food safety or hygiene risk. The compressible nature of the foam pad allows it to conform to the pack contours while applying gentle, evenly distributed pressure. This cushioning effect prevents point-loading on any single pack, reducing the incidence of burst seals, corner damage, or film punctures. For premium wet wipe brands that demand pristine product presentation, this protective handling is invaluable.

Finally, full-surface sponge grippers reduce long-term maintenance costs. Unlike small suction cups that can tear, clog, or deform individually—requiring frequent replacement—the foam pad is a single, durable component that typically lasts for millions of cycles before requiring replacement. At TECHFLOW PACKAGING SOLUTIONS, we specify high-quality, oil-resistant foam materials and integrated vacuum filtration systems to maximize pad longevity and minimize maintenance interventions.

Question 8

What Special Requirements Apply to the Gripper Tool of a Pick-and-Place Wet Wipes Case Packer?

Accepted Answer

The gripper tool (also called the end effector or vacuum gripper assembly) is arguably the most critical component of any pick and place case packer used for wet wipes. Because wet wipe packs are flexible, lightweight, and sometimes prone to air leakage through their packaging film, the gripper design must be carefully engineered to ensure reliable pick-up, stable transport, and gentle release into the carton—without dropping packs or causing package damage. At TECHFLOW PACK, we invest significant R&D resources into gripper optimization because we understand that a poorly designed tool can reduce line efficiency by 20% or more due to dropped products, misaligned packs, and emergency stops.

The specific gripper requirements depend heavily on two factors: the product orientation inside the carton and the number of pack specifications the machine must handle. If wet wipe packs are loaded into the carton in a flat (horizontal) orientation, the gripper design is relatively straightforward. In this scenario, a multi-row array of small-diameter vacuum suction cups or a single row of foam vacuum pads can typically achieve sufficient holding force across the relatively flat top surface of the pillow pack. The vacuum is distributed evenly, and the low profile of the gripper allows for easy insertion into shallow cartons.

However, when wet wipe packs must be loaded in a vertical (standing) orientation—for instance, when packing two layers with 5 to 10 packs per layer—gripper design becomes significantly more complex. In vertical packing, the gripper must engage the narrow side edges or top seals of the packs, where the surface area available for vacuum adhesion is limited. Under these conditions, multi-row arrays of small-diameter suction cups often fail to maintain vacuum integrity, especially if the pack film is slightly wrinkled or porous. The result is frequent "dropped pack" incidents that disrupt production. To solve this challenge, TECHFLOW PACKAGING SOLUTIONS engineers grippers with multi-row foam vacuum pads (also known as sponge vacuum grippers). The continuous foam surface conforms to minor irregularities in the pack geometry, creating a larger effective sealing area and distributing the vacuum force more uniformly across the group.

The material selection for the foam pad and the specification of the vacuum generator must be determined through rigorous testing with actual product samples. Factors such as foam density, porosity, compression set, and chemical compatibility with the wet wipe film must be evaluated. Similarly, the vacuum pump or ejector must be sized to provide adequate flow rate and vacuum level to hold the full pack matrix securely during the rapid acceleration and deceleration cycles of the robot. For manufacturers in the Middle East and Southeast Asia seeking a multi-specification wet wipes case packer, Shanghai TECHFLOW PACKAGING SOLUTIONS (TECHFLOWPACK) offers an outstanding solution: a single automatic wet wipes case packing machine that can seamlessly handle multiple pack counts—5, 6, 7, 8, or 9 packs per row—without requiring gripper changeovers, thanks to our proprietary adaptive foam gripper technology.

Question 9

What Are the Mainstream Wet Wipes Case Packing Methods Available on the Market?

Accepted Answer

In the global wet wipes packaging equipment market, three primary case packing methodologies dominate: pick-and-place (gripper) case packing, side-push (side-load) case packing, and wraparound case packing (also known as wraparound case packer or RSC wraparound systems). Each method is suited to different product characteristics, production speeds, carton styles, and end-market requirements. Understanding the distinctions among these technologies is critical when selecting the optimal wet wipes secondary packaging solution for your facility.

Pick-and-Place Case Packing is the most versatile and widely adopted method for flexible wet wipe packs. In this configuration, a robotic arm or Cartesian gantry system equipped with a vacuum gripper tool descends over the collated group of wet wipe packs, engages the vacuum suction cups or sponge pads, lifts the entire matrix, and places it into a pre-erected carton. This method is ideal for multi-layer packing configurations—for example, loading two layers of 5 to 10 packs each into a single carton. TECHFLOW PACK specializes in pick and place case packers that utilize Delta robots, 2-axis linear robots, or articulated robotic arms, depending on the speed and payload requirements. Pick-and-place systems are typically paired with American-style regular slotted containers (RSC) that are sealed with adhesive tape at the top and bottom flaps.

Side-Push (Side-Load) Case Packing operates by pushing the collated group of wet wipe packs horizontally into an open carton from the side. This method is mechanically simpler than pick-and-place and is well-suited for single-layer or flat-packed configurations where the product height is relatively low. Side-load case packers also use RSC cartons with tape sealing. They offer high speeds and robust reliability but may have limitations when handling multi-layer or vertically oriented pack patterns.

Wraparound Case Packing represents the third major category. In this system, a flat corrugated blank is fed into the machine, the wet wipe packs are placed onto the blank in the desired pattern, and the machine wraps the cardboard around the product bundle, folding and sealing the flaps with hot-melt glue. This method produces a tightly fitted, shelf-ready case that uses less corrugated material than traditional RSC cartons. Wraparound case packers are particularly popular in the beverage and dairy industries and are increasingly being adopted in wet wipes packaging lines where material cost savings and retail presentation are priorities. TECHFLOW PACKAGING SOLUTIONS offers all three case packing technologies, allowing clients to select the method that best aligns with their operational goals, budget, and downstream logistics requirements.

Question 10

Must Wet Wipe Packs Be Collected into Groups Before Case Packing?

Accepted Answer

Yes, product grouping (also known as collation or arraying) is an absolutely mandatory step in the wet wipes case packing process. Before any wet wipe pack can be loaded into a carton, it must first be organized into a predetermined matrix—commonly referred to as a "pack pattern"—that matches the case dimensions and the desired retail configuration. At TECHFLOW PACKAGING SOLUTIONS, we engineer our automatic wet wipes case packing machines with advanced collation systems to ensure that every case contains the exact number of packs arranged in the correct row-and-column configuration, whether that is 5 packs per row, 8 packs per row, 10 packs per row, or any other custom specification requested by the client.

The most prevalent collation technology in the wet wipes packaging industry today is the dual-servo collation system. This sophisticated mechanism utilizes two independent servo motors to precisely control the spacing, acceleration, and deceleration of wet wipe packs as they move through the grouping station. Unlike pneumatic or mechanical indexing systems that rely on fixed cams and can only handle one format, dual-servo collation offers exceptional flexibility. By simply adjusting the servo parameters through the HMI (Human Machine Interface), operators can switch between different pack counts—such as 5, 6, 7, 8, 9, or 10 packs per row—without performing lengthy mechanical changeovers. This capability is especially valuable for contract packagers and FMCG manufacturers who need to run multiple SKUs (Stock Keeping Units) on the same packaging line throughout the day.

The collation process typically works as follows: wet wipe packs exit the transition conveyor in a single lane and are fed into an accumulation buffer. A servo-driven pusher or lug chain then segments the packs into the required group size, while a second servo system aligns the rows into the final matrix. Once the complete group is formed, it is transferred as a solid block into the loading station of the case packer machine, where it is either picked up by a robotic gripper or pushed sideways into an open carton. Without this grouping step, individual packs would enter the case packing zone in a disorganized stream, making it impossible to achieve the neat, shelf-ready arrangement that retailers and consumers expect. Therefore, when evaluating a fully automatic wet wipes case packing machine, always verify the sophistication of its collation module—preferably a dual-servo system—to ensure it can accommodate your current and future product range with minimal changeover time.

Question 11

Is a Transition Conveyor Line Mandatory at the Front End of a Wet Wipes Case Packer?

Accepted Answer

Yes, absolutely. In any modern wet wipes packaging line, a transition conveyor (also referred to as a transfer conveyor or infeed buffering conveyor) is an essential upstream component that bridges the gap between the primary wet wipes packaging machine and the downstream automatic case packer. At TECHFLOW PACKAGING SOLUTIONS, we have observed that omitting this critical intermediate stage often leads to inconsistent product orientation, irregular spacing between wet wipe packs, and ultimately, downstream jamming at the case packing station. The transition conveyor performs multiple preparatory functions: it receives individually wrapped wet wipe packs from the flow wrapper or VFFS machine, aligns them into a uniform flow, and may gently compress or shape the flexible pillow packs to ensure they maintain a consistent profile before entering the collation zone.

From an end of line packaging automation perspective, the transition conveyor acts as a buffering and conditioning module. Wet wipes are inherently soft, flexible, and sometimes slightly inflated due to residual air trapped inside the pillow pack during sealing. Without proper conditioning on a transition conveyor equipped with side rails, guide plates, or light compression belts, these packs can arrive at the case packing machine in skewed or overlapping states, causing misfeeds and unplanned downtime. Furthermore, the transition conveyor allows for product reorientation—converting the flow from single-file to multi-lane, or rotating packs by 90 degrees—to match the infeed requirements of the specific wet wipes case packer model in use. For high-speed operations running at 80 to 150 packs per minute, this reorientation must happen smoothly without product damage or accumulation pressure.

TECHFLOW PACK designs transition conveyors as modular, stainless-steel units with adjustable side guides and synchronized variable-frequency drives (VFDs) to match the upstream and downstream machine speeds precisely. Our conveyors are engineered with food-grade belt materials and easy-clean surfaces, complying with hygiene standards required in the personal care and baby wipes industries. Whether you are integrating a pick and place case packer, a side-load case packer, or a wraparound case packer, the transition conveyor ensures that the wet wipe packs arrive at the grouping station in perfect condition—properly spaced, correctly oriented, and ready for high-speed collation. Investing in a well-designed transition conveyor is therefore not optional; it is a foundational requirement for achieving reliable throughput, minimizing product waste, and maximizing the overall equipment effectiveness (OEE) of your wet wipes secondary packaging operation.

Question 12

What necessary treatments must the French fry bags undergo before case packing?

Accepted Answer

According to the production line layout of Techflowpack , the bags fall into the buffer hoppers by photoelectric counting to complete the grouping (5-10 packs or customized).Carton magazine are automatically formed and sealed at the bottom by an opening machine and then conveyed along a roller conveyor line to the Case packing station. A pneumatic device lifts the carton 90 degrees to align with the discharge outlet of the buffer hopper. The side push mechanism of the case packer pushes the grouped bags into the carton according to photoelectric signals and PLC instructions. After the carton is lowered 90 degrees by the pneumatic device, it enters the roller conveyor line for online weight inspection. Qualified cartons are then marked with a laser coder and automatically sealed by tape sealer. The sealed cartons are automatically palletized by a robot, and then automatically wrapped with a stretch wrapper on the pallet before entering the automated warehouse for storage and turnover. Due to the sealing characteristics of the VFFS packaging machine, some manufacturers make holes in the bags to release excess air inside. After passing through metal detection and weight checking, the French fry bags are flattened by a vibrating conveyor belt, and then pass through a perforated vacuum belt, where they enter the case packing station smoothly by means of negative pressure adsorption.

Question 13

What necessary inspections are required for bagged French fries before case packing?

Accepted Answer

Commonly available bagged French fries on the market typically undergo weight checking and metal detection. Techflowpack pays close attention to customer needs and has designed and developed a series of bagged food packaging solutions, covering automated handling, conveying, metal detection, case packing, weighing, and palletizing. According to the production line layout, the sealed fries bags are then conveyed by a belt conveyor through online metal detection, X-ray inspection, and weight checking, and then enter the vibratory shaping conveyor. After shaping, the bags enter the Case Packer’s buffer conveyor line, where they undergo vacuum exhaust and wait for grouping. Some customers have stricter quality control requirements; in addition to the above two inspections, they also add X-ray inspection. If foreign objects such as fruit peels, hair, or paper scraps are found inside the French fry bag, they will also be rejected from the production line.

Question 14

How to select the packaging film material for frozen French fries?

Accepted Answer

With the rapid development of modern social economy, people have increasingly higher requirements for food safety, and food packaging technology is continuously being upgraded accordingly. Based on material characteristics and packaging cost control considerations, the mainstream packaging methods currently on the market include bagging, bottling, and cartoning. Frozen French fries are different from fried French fries and fried potato chips available on the market, and have special requirements for packaging materials. At present, the most commonly used packaging material for frozen French fries on the market is PE film, due to its better toughness and economic attributes.

Question 15

How to select the right case packer for bagged French fries?

Accepted Answer

Clients can refer to the case packing methods of similar products in the target market. There are two common methods in the market: side-loading type and drop packer. The side-loading case packer places the grouped French fry bags into the carton in an upright orientation. For example, 1kg bags are typically packed 10 bags per carton. The drop packer, also known as a gravity drop case packer, operates on the principle of free fall, allowing the French fry bags to drop from above into the carton via a flap plate in a flat orientation, and then stack them layer by layer according to quantity. Based on market feedback, European customers can purchase Dutch BPA French fry case packers; Southeast Asian customers can purchase Shanghai's TECHFLOW PACKAGING SOLUTIONS (Techflowpack) French fry case packers. During the End of Frozen French Fries Bagging and Case Packing Production Line, Techflowpack choose to adopt the Automatic Side-Loading Case Packer, which features a user-friendly HMI interface with fault alarm and traceability functions. The design is simple in structure, easy to clean and maintain. Electrical components can be customized according to customer requirements. Its operating language can be customized according to the requirements of overseas customers. Also, switching between multiple product specifications is convenient, and the operator can easily master the operation.

Question 16

How to select the right packaging machine for frozen French fries?

Accepted Answer

Techflowpack has already exported to North America, the Middle East, Eastern Europe and other countries, so it can design the packaging bag style (commonly a pillow bag), and determine the packaging weight and bag dimensions according to the target market consumer preferences. It is quite common to select the appropriate pouch packaging machine based on the bag size. For bag’s width less than 250mm, use the VFFS520; if bag width less than 350mm, use the VFFS720.; as for bags that fill 1 kg, use the VFFS720. Based on equipment performance, packaging efficiency, and film waste, European customers are recommended to purchase BOSCH and WOLF; North American customers are recommended to purchase ROVAMA (US); Southeast Asian customers are recommended to purchase Shanghai's TECHFLOW PACKAGING SOLUTIONS (Techflowpack).

Question 18

Is the transfer conveyor line made of belt or stainless steel?

Accepted Answer

According to the production line layout, the French fries coming out of the quick-freezing discharge outlet first fall into a SUS304 quick vibrating pusher with raised dots on the surface to prevent the fries from piling up, and are then distributed to the belt conveyor via the quick vibrating pusher. After being lifted by the belt conveyor, the fries enter a multi-head electronic weigher to complete the weighing and dosing according to the preset weight.

Question 19
