Food packaging materials testing
The quality and safety of food directly affects the health of the people. Packaging is an important part of food and plays an important role in the quality protection of products after they leave the factory. Plastic packaging, as the mainstream form of packaging today, is widely used in the packaging of all kinds of commodities, especially in the food industry. Our daily consumption of liquid/semi-liquid foods, powdered foods, and solid foods are based on plastic packaging. Usually we use the different characteristics of the material to use them together according to actual needs.
