Advantages of PET as a packaging material: 1. It has good mechanical properties, with an impact strength 3-5 times that of other films, and good bending resistance. 2. Oil resistant, fat resistant, acid and alkali resistant, and resistant to most solvents. 3. It has excellent resistance to high and low temperatures and can be used for a long time within the temperature range of 120 ºC. It can withstand high temperatures of 150 ºC and low temperatures of -70 ºC for short-term use, and its mechanical properties are minimally affected by high and low temperatures. 4. Gas and water vapor have low permeability and excellent resistance to gas, water, oil, and odor. 5. High transparency, can block ultraviolet rays, and has good gloss. 6. Odorless, good hygiene, can be directly used for food packaging
