What steps should be taken into account when packing yogurt cups?

The packaging of yogurt cups should take into account hygiene and safety, transportation protection, and efficiency optimization. The following is a systematic review of key steps:

1、 Preprocessing stage: Packaging integrity confirmation
Sealing integrity test
Use a vacuum sealing tester to test the sealing strength of the cup film to avoid air leakage and deterioration.
Verify the peeling force of the cover film (refer to GB 8808 standard) to ensure that it is not easy to accidentally peel off and is easy for consumers to open.
Material compliance
Packaging materials must comply with the National Food Safety Standards, with priority given to PET/PP materials that are acid resistant (pH 3.5-5.0) and have strong oxygen resistance.
Check if the packaging container has QS logo 2 to eliminate the risk of harmful substance migration.
2、 Core steps of packing operation
1. Seismic protection design
Comprehensive shock-absorbing packaging: Fill the box with cushioning materials such as bubble wrap and pearl cotton, and use compression packaging or floating packaging methods to absorb impact forces.
Layered isolation: Each layer of yogurt cup is separated by corrugated cardboard to avoid deformation of the cup body caused by stacking.
2. Space optimization and stability
Reasonable stacking: Place lighter boxes on the upper layer and heavier boxes on the lower layer; Use packing software (such as leisurely packing) to calculate the optimal layout and increase the loading rate to over 95%.
Fixing measures: the space in the box shall be filled with inflatable bags or foam blocks to prevent shaking and collision during transportation.
3. Parameter optimization of automation equipment
Mechanical arm grasping: using suction cup type fixtures to smoothly grasp the cup body, avoiding direct hand contact.
Equipment settings: Adjust the box type parameters, mechanical arm speed, and labeling position of the packaging machine according to the size of the cup, and debug the accuracy through simulation operation.
3、 Cold chain and hygiene management
Temperature control: Maintain an environment of 2 ° C-6 ° C throughout the entire process. Pre cooling facilities should be equipped in the packaging area to avoid microbial imbalance after yogurt leaves the refrigeration chain.
Cleaning process: Operators are required to wear sterile work clothes and gloves, and regularly perform food grade disinfection on the packaging equipment.
4、 Final inspection and compliance acceptance
Box integrity
Check the cardboard box for any damage or stains, and the sealing tape should completely cover the box seam 3.
Label information verification
The outer box should be clearly labeled with the production date, batch, storage temperature, and the "Fragile" label.
Sampling mechanism
Randomly open the box to verify if the cup arrangement is tight and if there is any leakage, and record the sampling result 1.
5、 Special scenario precautions
Export transportation: If cross-border logistics is involved, additional compliance with destination country standards (such as CE certification) and the use of moisture-proof composite film to cope with the shipping environment are required.
Environmental trend: biodegradable PLA materials can be gradually adopted for packaging, taking into account the needs of sustainable development.
By systematically controlling the above links, the damage rate and quality risk of yogurt cups in the logistics process can be significantly reduced. If further refinement of the plan is required for specific packaging specifications (such as multi cup, irregular cup), specific parameters can be provided for in-depth analysis.
