Food packaging material testing

The quality and safety of food directly affects the health of the people. As an important part of food, packaging plays an important role in the quality protection of products after they leave the factory. As the mainstream packaging form today, plastic packaging is widely used in the packaging of various commodities, especially in the food industry. Our daily consumption of liquid/semi-liquid food, powdered food, solid food, etc. are mainly plastic packaging. Usually we use different characteristics of materials to compound them together according to actual needs.
