The main functions of PET cover include protection, display and preservation.
Protective function: PET cover can effectively protect food from pollution and damage from the external environment. It has good transparency and mechanical properties, can block ultraviolet rays, gas and water vapor, thereby extending the shelf life of food. Display function: High-transparency PET cover is particularly suitable for scenes that require high transparency display, such as fruit cutting. It can remain clear in low-temperature freezers, avoid the situation where the ingredients cannot be seen clearly, and make the display of fresh ingredients more intuitive. Preservation function: PET cover can effectively isolate air, prevent food from oxidation and deterioration, thereby extending the shelf life of food. In addition, PET material has good high and low temperature resistance, and can maintain stable performance in a wide temperature range.
