The content of the Food Hygiene Law is more comprehensive than the management methods, which are professional and only refer to plastic products and raw materials. The scope of management is limited to various plastic tableware, containers, production pipelines, conveyor belts, and packaging materials made of plastic that come into contact with food, as well as the synthetic resins and additives used. The so-called plastic tableware refers to plastic products such as spoons, spoons, chopsticks that come into contact with food for a short period of time but need to be reused. The so-called container refers to plastic products such as barrels, bottles, pots, and cups that hold food. The so-called production pipeline refers to the pipeline through which materials, especially liquid food or beverages, flow during the food processing process, and should also include storage and filling. The so-called conveyor belt refers to the carrier used to transport food raw materials to processing equipment, while packaging materials refer to single and composite bottles, barrels, trays, rolls, and bags, including roll wrap packaging film, sealing film, and bag making film. All manufacturers of food flexible packaging and composite packaging materials should strictly implement this management method.
