GB 9686-1988 "Hygienic Standard for Polyamide epoxy resin coatings on the inner walls of food containers" specifies the hygiene requirements for polyamide epoxy resin coatings used on the inner walls of food containers. The standard aims to ensure that the coating does not release harmful substances during contact with food, and to ensure the safety of food and consumer health. The standard describes in detail the chemical composition, performance requirements of polyamide epoxy resin coatings and their requirements for non-toxicity and Stability to food. In addition, the standard also specifies detection methods for evaluating the safety and durability of coatings under high temperature, high humidity and other conditions. By following this standard, food container manufacturers can ensure that their products meet hygiene requirements, thereby reducing the risk of food contamination and increasing product mass.
