Packaging materials For food production companies, people have been exploring packaging materials and containers that can replace glass bottles and tin cans for more than 30 years, and polyester film is the best material currently available. It features light weight, which reduces shipping costs. But not every PET polyester film is suitable for food packaging.

In the early 1970s, acrylonitrile plastic containers were the first to appear in the market. However, the US Food and Drug Administration (FDA) later revoked the approval of the use of this container material in food. The main reason is that a certain chemical substance in this packaging material will migrate too much to the packaging container. in the content. Polyvinyl chloride (PVC) plastic containers are also quickly becoming undesired materials due to environmental concerns.

The emergence of PET polyester film materials has led to the rapid development of food packaging. The first company to use PET bottles to package refreshing beverages is the Coca-Cola Company of the United States. They replaced 1 liter glass bottles with 1.5 liter polyester bottles, resulting in a 27% increase in retail sales. After that, food and beverages packaged in PET containers gradually became popular "sought-after goods". The light weight and robustness of PET containers attract customers and are expected by the market. Another great advantage of PET material is that it can be formed into any shape (good applicability), and at the same time, it can be processed into a color that suits everyone's preferences, and can be used for text and image printing.
