The analysis of PE cling film manufacturers is divided into: polyethylene, polyvinyl chloride and other types according to the material. Among them, everyone needs to understand that PE fresh-keeping bags and PVDC fresh-keeping bags are relatively safe in their types. PE is used for packaging of fruits and vegetables, while PVDC is mainly used for packaging of cooked food and ham.
PE cling film manufacturers analyze that PVC cling bags are currently used more frequently in the outer packaging fields of food and vegetables, but there is some potential harm to the human body in terms of quality. Because there are two substances in PVC that are carcinogenic, VCM and DEHA. If the composition of VCM is non-toxic in the range of 1PPM, it will be carcinogenic if it exceeds the standard.
1. PE cling film manufacturers recommend that you pay attention to the material of the product label: polyethylene bags (pe) are more commonly used in food packaging; polypropylene bags (pp) have better transparency and are used for bread, snacks, etc .; Polyvinyl chloride bags (PVC) can also be used for packaging of perishable foods such as vegetables and fruits. They cannot be used for packaging greasy foods, and they cannot be used for microwave oven heating.
2. PE cling film manufacturers recommend that when you use microwave ovens to heat food, you must use "microwave oven" fresh-keeping bags.
3. PE cling film manufacturers analyze the refrigerated and frozen foods in daily refrigerators. They should also be packaged in fresh-keeping bags instead of ordinary plastic bags.
