Due to its excellent physical and chemical properties, PET film is widely used in the field of food packaging. However, its monomers, catalysts and other additives, including by-products, are highly toxic substances, and there is a risk of migration. With the progress of petrochemical technology, China has developed rapidly in the polyester industry, and has now become the world's largest production base for polyester products. Because of its excellent rigidity, heat resistance, electrical insulation and chemical resistance, it is widely used in the production of bottles, fibers, and films. In the process of polycondensation, PET needs to add catalysts (such as antimony trioxide), stabilizers and other additives or assistants. At the same time, there are by-products (such as diethylene glycol, acetaldehyde and some oligomers) during the esterification reaction. ), and some of these substances are toxic, and will migrate to the contents through packaging materials during contact with food, which will lead to contamination of the contents and further affect the health of consumers.
