When buying plastic wrap (bag) products, it should be noted that when buying plastic wrap (bag) products in supermarkets, the packaged products should be selected, and the packaging bags should not be damaged. Pay attention to the production date and shelf life, and try to choose products within the shelf life to prevent the growth of bacteria and mold. Pay attention to product identification and try to buy plastic wrap/bag made of polyethylene (PE) without plasticizer. The safety of products using this raw material can be guaranteed. The product packaging should be marked with the implementation standard to prove that it meets the standard requirements. The plastic wrap/bag with flat surface and no bubbles, perforations, cracks, impurities and foreign bodies shall be selected.

In addition, when buying food cling film, you can smell it first to see if there is any peculiar smell or odor, otherwise it will be mixed with food and affect food safety. Touch the plastic package/plastic bag by hand. The plastic wrap/bag should be quite scratched and sticky, so that the plastic wrap can be easily opened during use, and the plastic wrap can be easily stuck on tableware to ensure the freshness of food and prevent the food from smelling.
