National food safety standards
Plastic materials and products for food contact
1 Scope
This standard applies to plastic materials and products for food contact, including unvulcanized thermoplastic elastomer materials and products.
This standard also applies to starch-based plastic materials and products for food contact.
2 Terms and definitions
2.1 Resin
Using the corresponding monomers and other starting materials as the main raw materials, it is synthesized through polymerization reactions such as addition polymerization, condensation polymerization, and microbial fermentation polymerization.
Made of macromolecular substances, as well as chemically modified natural or synthetic macromolecular substances, also known as polymers.
2.2 Resin blends
Two or more polymers with the same or different chemical structures and physical states are mixed by physical and/or chemical methods
Macroscopically uniform and continuous solid polymer materials are formed, and each polymer can be used as the main structural component of resin materials and their products.
Separate or phase, also known as polymer blends or polymer alloys.
2.3 Plastic materials
One or several resins (including resin blends) or their premixes, prepolymers, etc. are used as the main structural components, and necessary additives are added.
Polymer materials processed under a certain temperature and pressure and between resin and plastic products, including plastic pellets (or slices), powder
Plastic materials such as powder, masterbatch, and sheets.
2.4 Plastic products
It uses resin (including resin blends) or plastic materials as raw materials, adds necessary additives, and is molded and processed into a final product with a certain shape.
Molded products (or final products) that come into contact with food.
2.5 Masterbatch
Additives that affect the physical properties of plastic materials and products (such as colorants, fillers, reinforcing agents, stabilizers, etc.) are excessively loaded into a or
It is a concentrate made from several resins and mixed with resin or plastic materials to be processed into other plastic materials and products.
3 basic requirements
Plastic materials and products used for food contact should comply with the regulations of GB 4806.1.
4 Technical requirements
4.1 Raw material requirements
4.1.1 The use of resin in food contact plastic materials and products should comply with the provisions of Appendix A and relevant announcements.
