Food packaging materials refer to paper, bamboo, wood, metal, enamel, ceramics, plastics, rubber, natural fibers, chemical fibers, glass and other products used for packaging, food or food additives, and coatings that directly contact food or food additives. Since food packaging materials are in direct contact with food, Article 33 of the Food Safety Law states: “(7) Non-toxic, clean packaging materials, tableware, drinking utensils and containers shall be used for foods directly imported. Ensure that the packaging materials themselves are safe, non-toxic and non-volatile, and that during the implementation of the packaging process, there will be no substances or chemical components that chemically react with food ingredients. This article will introduce you to the classification of packaging materials.
The advantages of packaging materials are reflected in the use of materials, pollution, pollution, recycling and reuse, without secondary pollution. Therefore, the selection of environmentally friendly packaging materials should be consistent with the basic principles of pollution-free, non-polluting and recyclable. Pure natural environmental packaging materials, although non-polluting, have high commercial costs and are a waste to the earth's capital. Composite environmentally friendly materials will become the mainstream trend of environmentally friendly packaging materials because of their low cost, no pollution, and easy recycling. .
The packaging material needs to have an effective bacteriostatic effect to ensure that the sterile machine is free from external bacterial contamination for a long time: at the same time, the packaging material is required to have permeability to the sterilization factor, and does not affect the sterilization factor to the bacterial microorganism. Kill function.
Packaging materials are one of the necessary conditions for electronic products to fulfill their functions. They not only affect the overall function of the product packaging, but also the quality problems of the electronic products during transportation and storage. In addition to ensuring that electronic products are protected from outside harm, the selection of packaging materials should also be oriented towards conservation and environmental protection.
Due to the complexity of the composition of the packaging material, the precipitation of substances in the food packaging material occurs in the food, possibly due to the migration of these substances to the food, or in the food due to accidental extraction. This causes chemical migration of food packaging to have a negative impact on food.
