In terms of strength, PVDC material is the best, PVC material is the second, and PE material is the worst. Overall, the self-adhesive, tensile strength, barrier properties and other performance values of PVDC cling film are significantly better than PE cling film.

Provincial Consumer Protection Committee recommends that coffee, tea, dried fruit, etc., need to choose a zipper ziplock bag with good water vapor barrier performance; tomatoes, apples, bananas, etc. will release ripening agent (ethylene), which should be put into breathability. And fresh fruit and vegetable storage bags with good moisture retention, then put them in the refrigerator for storage.

Buy foods with grease as much as possible. Consumers may see them in their daily lives. Some supermarkets, roadside dishes (cooked food) stores, use plastic wrap to wrap foods containing fat. However, when the PVC cling film is exposed to oily foods, it is easy to produce plasticizers and the like, which affects the health of the body. Or ordinary consumers are not easy to distinguish the material.

Therefore, the Provincial Consumer Protection Committee reminded that when purchasing non-prepackaged foods containing fat, try to bring the packaging utensils as much as possible, and do not wear plastic wrap to heat. At the same time, it is also hoped that the operators will strengthen self-discipline and express materials, and the relevant administrative supervision departments will further strengthen supervision.

The Consumer Protection Committee also recommends that consumers try to purchase PE self-adhesive wrap film or fresh-keeping bag; use it according to the temperature range specified in the package; do not reuse the disposable wrap film; Do not use a microwave oven to heat the film.
