we can help you find the answer here, first of all, we generally use of food packaging materials have BOPP compound CPP; PET composite CPP; PE composite BOPP. PA composite PE composite PET, such as compound CPP BOPP production of finished product bag is bright but is soft, PET composite CPP products bright good hardness, PE composite BOPP products thick but transparency is not high, and so on, we mentioned here say PET is the title of polyester, as long as the characteristics of the material is good brightness, more crisp, to produce food packaging bags is pretty solid, compared with the thickness of the same product than hard have stereo feeling. Actually see all of the main characteristics of polyester film is clearly know why polyester composite food bag burst and leakage reason?

the main reason is because of the cold winter weather, polyester film is more three-dimensional crisp material, will be easily crack in cold weather, flat, open, so recommend during the cold season, do not have to choose the type of food packaging.
