Advantages of PET cake box:
1. good mechanical properties, impact strength is 3~5 times that of other films, good folding resistance;
2. excellent resistance to high and low temperature, can be used in the temperature range of 120℃ for a long time.
150℃ for short-term use and -70℃ for low temperature, and high and low temperatures have little effect on its mechanical properties;
4. low permeability to gas and water vapor, strong resistance to gas, water, oil and odor;
5. high transparency, ability to block ultraviolet rays and good gloss;
6. non-toxic, tasteless, good health and safety, can be used directly in food packaging.
