Degradation Performance Of Food Packaging Bags

According to the different degradation types of products, they can be divided into photodegradation type, biodegradation type, and environmental degradation type. Degradation performance reflects the ability of a product to be accepted by the environment after being discarded. If the degradation performance is good, the bag will break, differentiate, and degrade on its own under the combined action of light and microorganisms, ultimately becoming debris and accepted by the natural environment; If the biodegradability is poor, it will not be accepted by the environment, resulting in "white pollution".
The inspection items for food packaging composite film bags are mainly divided into the following categories:
The appearance should be flat, without scratches, burns, bubbles, oil breaks, and wrinkles, and the heat seal should be flat and free from false seals. The film must not have cracks, pores, or separation of the composite layer. No contamination such as impurities, foreign objects, and oil stains.
The bagged soaking solution must not have any odor, odor, turbidity, or discoloration.
It should be pointed out that in addition to the corresponding hygiene standards mentioned above, there are also two laws and regulations in China regarding food packaging materials: first, the Food Hygiene Law of the People's Republic of China, and second, the Management Measures for Plastic Products and Raw Materials Used in Food.
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.
