Plastic packaging and polymeric material 💧

Common materials for plastic food and liquid packaging pouch, including polyethylene, polypropylene, polystyrene, polyvinyl chloride, polyvinylidene chloride, etc., are polymer materials. This kind of material is formed by chemical polymerization of monomers. It has large molecular weight and high stability, and will not easily migrate to food.


⏯In China, for example, food packaging belongs to the supervision category of food safety law. In the national food safety standard general safety requirements for food contact materials and products, the amount of plastic transfer in the case of contact with food shall not exceed 0.01mg/kg, which will not pollute the food.


Formal food packaging and food production enterprises must pass strict evaluation procedures of relevant government departments and product quality inspection to be granted production license. This procedure ensures that packaging materials meet food safety requirements and will not harm human body.


Moreover, there is no scientific evidence that plastic packaging can cause cancer, the cause of which is very complex and cannot be attributed to plastic simply.

If we used plastic bags to contain food before, we should not worry too much. As long as the harmful substances do not exceed the national standards, they will not cause harm to the human body, and the human body has metabolic function for harmful substances such as plasticizer. If not consumed in large quantities for a long time, we should not worry too much.
