(Summary description)In daily life, many people use plastic bags to hold food. So what kind of plastic packaging bag is safe?ince the implementation of the plastic bag restriction order, we have learned more about the concept of environmental protection. Recently, the national standard for plastic shopping bags has been released to the public. It includes "General Skill Requirements for the Environment, Safety and Identification of Plastic Shopping Bags", "Plastic Shopping Bags" and "Quick Inspection Methods and Evaluations of Plastic Shopping Bags". The release of this specification not only meets the needs of environmental protection, but also meets everyone's health and safety. Nowadays, there are many kinds of plastic bags, especially plastic bags used for food. But through the professional introduction of the skilled personnel of the plastic bag manufacturer: Now we can guarantee to directly touch or hold the plastic products used for food, especially the plastic bags only need polyethylene and polypropylene plastics. These two plastics cannot be used as additives when used to make food bags, so they are completely non-toxic. They are products allowed by the state, but the quotations are more expensive. Generally, plastics used for non-contact foods are made of PVC or the like. PVC is cheap, easy to color and bright color, not easy to deform, easy to process, and can add a variety of additives. This plastic is widely used, such as industrial and agricultural plastics, daily necessities, raincoats, sandals, toys, etc. PVC is a big plastic production in China. The main reason why it cannot be used in food packaging is that it is suspected of toxicity. PVC has two sources of toxicity. One is the quality of vinyl chloride plastics. Fully polymerized PVC is a high molecular compound and will not be absorbed by humans and animals. It is completely non-toxic. Its toxicity lies in the toxicity and carcinogenicity of free vinyl chloride monomers that have not yet been fully polymerized. The second is the toxicity of additives during polymerization. Many industrial additives are toxic.
