Parameters

Actual performance tests (factory measured data)

1. Special test for barrier performance

The factory completed special tests for water vapor permeability and oxygen permeability in batches. The vacuum-coated aluminum layer was dense and uniform, with stable oxygen and moisture barrier indicators. Compared to ordinary PET films, the barrier performance of this product was improved by several times. After simulating normal temperature storage, high-temperature and humid transportation environments, it could effectively prevent water vapor and oxygen from invading. It could store food for a long time without food spoilage or packaging bulging, meeting the standard for long-term food preservation.

2. Adhesion and wear resistance test of coating

Through repeated friction, bending, and peel-off wear resistance tests, the aluminum coating did not peel off, did not lose powder, or show exposed base. The inner-coated products, after multiple printing, compounding, and die-cutting processing, still met the integrity standards of the coating. This completely solved the pain point of aluminum detachment and scrap during mass production and was suitable for high-frequency automated processing.

3. Double-sided corona stability test

Samples were taken from the head, tail, and middle of each roll of BOPET Metallized Film for PET food packaging for sampling tests. The durometer values on both sides were strictly stable within the standard range, with no local parameter deviations. After a 3-month static storage simulation test at normal temperature, the corona value decay was extremely low, and it still maintained excellent printing and compatibility after storage, with extremely strong inventory stability.

4. Mechanical weather resistance performance test

Through stretching, puncture resistance, and bending resistance simulation tests, the product substrate had sufficient toughness. After filling, stacking, logistics compression, and bending molding, it was not prone to damage or air leakage. At the same time, high-temperature and low-temperature weather resistance tests were completed. Under the normal temperature storage temperature difference environment, the coating did not oxidize, change color, or delaminate, and was suitable for climate in multiple regions across the country and cross-border ocean transportation.

5. Appearance color consistency test

Our BOPET Metallized Film for PET food packaging uses a fully automatic optical color difference detection device. Batch products have uniform color and no dichromatic color, no local gloss differences. Customized gold and colored coatings have no color difference and are uniformly colored, ensuring that the visual effect of batch-packaged products is highly consistent and meeting the requirements of brand standardized packaging.
