What should I pay attention to when purchasing an automatic milk boxes Wraparound Case Packer ?

When purchasing an automatic milk boxes wrap around case packaging machine, multiple factors such as equipment performance, compliance requirements, and supplier services need to be considered comprehensively. The following are key precautions:

1、 Technical requirements for equipment
Capacity and adaptability
Confirm whether the packaging speed of the equipment (such as 1500-2200 bags per hour) matches the production line requirements, and check the capacity range of milk cartons that can be processed (such as 200-1000ml).
Ensure that the equipment can adapt to the material and shape of the milk carton, avoiding jamming or loose packaging.
Health and Safety Standards
The components of the equipment that come into contact with food must be made of non-toxic and corrosion-resistant materials such as stainless steel, and comply with the mandatory national standard GB 16798-2023 "Safety Requirements for Food Machinery".
The structural design should be easy to clean, without any hygiene blind spots, and prevent the growth of microorganisms.
Automation and Stability
Priority should be given to fully automatic models with high integration and easy operation, supporting full process automation such as parameter setting, sealing, and coding.
Check the reliability of core components such as PLC control systems and servo drives to ensure long-term stable operation.
2、 Key points of supplier evaluation
Qualifications and reputation
Verify the manufacturer's production qualifications, patented technology, and industry cases (such as whether they have served dairy companies), and refer to customer evaluations (such as feedback from suppliers like Three Squirrels and Want Want 456).
Request to provide equipment demonstration or trial run to visually verify performance.
After sales service and technical support
Clearly define the specific contents of installation and debugging, operation training, regular maintenance, and accessory supply services, and prioritize selecting suppliers with quick response (such as 24-hour after-sales service).
When signing the contract, specify the warranty period and division of responsibilities to avoid subsequent disputes.
3、 Compliance and Cost Control
Compliant with industry standards
The equipment must meet the acceptance standards for liquid food packaging (such as the requirements for aseptic filling in GB/T 19063), especially in terms of sealing and anti contamination design.
The electrical system should have safety signs (such as anti electric shock warning signs) that comply with GB 2894 standard 38.
Cost effectiveness and long-term costs
Compare the initial purchase price, consumables cost (such as film material thickness of ≥ 80 microns), and maintenance cost, and choose option 4 with high comprehensive cost-effectiveness.
Pay attention to energy-saving design and reduce energy waste.
4、 Acceptance and operation preparation
On site acceptance: Test packaging accuracy, sealing strength, and operating noise, and check whether the equipment nameplate parameters are consistent with the contract.
Operation training: Suppliers are required to provide detailed training, including safety regulations (such as strictly prohibiting contact with moving parts during operation) and daily cleaning and maintenance methods.
