Food plastic bags can be safely used, but do not use colored plastic bags for food. The plastic polyethylene, polypropylene, polyester, polystyrene, etc. currently used for packaging food have qualified hygienic properties and are safe for food packaging. However, consumers cannot distinguish between food and non-food plastic bags, so a considerable number of unqualified food packaging bags are used in food packaging, which seriously endangers people's health. In the use of food plastic bags, everyone must want to use safer food plastic bags. Then I will teach you how to tell whether food plastic bags are available.

The plastic bags we use are divided into food and non-food. The main raw material for food is pure polyethylene. This raw material has no chemical toxicity and is recognized as a non-toxic plastic raw material in the world. The products produced with it are of course safe. , All plastic bags that are in direct contact with food must have the words "for food", and must be marked with the QS and serial number of the food safety license issued by the General Administration of Quality Supervision, Inspection and Quarantine.

Non-food plastic bags cannot be used to hold food. The white or colored plastic bags we use in the vegetable market, the unmarked white plastic bags used for fried dough sticks, pancakes and other foods at the breakfast point, and in small noodle restaurants, In order to reduce the number of washing dishes, the white plastic bags on the bowls do not meet the food packaging requirements. Non-food plastic bags, if used to hold food that is not directly imported, such as vegetables, grains, etc., the pollution level of the filling masterbatch industry is relatively low, but if it is used to directly pack high-temperature foods such as rice porridge and hot fried dough sticks, or food that has been stored for a long time When it is used, some harmful substances will be volatilized, which will cause great pollution to food and cause harm to human health.
