The main changes of this standard are as follows, comparing with above standards and announcements:

— Other physical and chemical indexes is added;

— Other technical requirements is added;

1 Scope

This standard applies to food contact plastic materials and articles, including unvulcanized thermoplastic elastomer materials and articles.

This standard also applies to the food contact starch-based plastic materials and articles.

2 Terms and definitions 2.1

macromolecular substance that is synthesized by addition polymerization, condensation polymerization, microbial fermentation polymerization and other polymerization reactions with corresponding monomer and other starting materials as main raw materials, as well as chemically modified natural or synthetic macromolecular substance, it is also known as the polymer macroscopically uniform and continuous solid polymer material which is blended with two or more polymers with the same or different chemical structures and physical states by physical and/or chemical methods, in which each polymer can be used as the main structural constituent or phase of resin materials and articles, it is also known as polymer alloy polymer materials between resin and plastic articles that is made by taking one or several resins (including resin blends) or their premixes and prepolymers as main structural constituents, adding necessary additives and processing under certain temperature and pressure, including plastic granules (or chips), powders, masterbatch, sheets and other plastic materials finished food contact articles (or final products) with certain shape which are processed by taking resin (containing resin blend) or plastic materials as raw materials and adding necessary additives condensate that is made by overloading additives (such as colorants, fillers, reinforcers, stabilizers, etc.) that affect the physical properties of plastic materials and articles in one or several resins, and can be processed into other plastic materials and articles by blending with resin or plastic materials

3 Basic requirements

The food contact plastic materials and articles shall meet the requirements of GB 4806.1.

4 Technical requirements

5 Others

Annex A Allowable resins in food contact plastic materials and articles and

A.1 Table A.1 specifies the list of allowable plastic resins in food contact plastic materials and articles and their application requirements. The resins listed in Table A.1 shall be subject to CAS No., and those without CAS No. shall be subject to their English names. A.3 If monomers or other starting materials used in the synthesis of resins in Table A.1 are acids, alcohols or phenols, their sodium, potassium and calcium salts (including acid salts and double salts) may also be used in the synthesis of corresponding resins, and shall meet the restrictive requirements of the corresponding acid, alcohol or phenolic monomers or other starting materials. Sodium, potassium and calcium salts (including acid salts and double salts) of monomers or other starting materials listed in Table A.1 shall be used according to the requirements of this standard. A.4 See Annex B for the abbreviations of general category names of various plastic resins in Table A.1. It shall not be used in contact with foods containing ethanol, and the service temperature shall not be higher than 100°C PVDF ND (hexafluoropropylene: SML, DL=0.01mg/kg); 5 (vinylindene fluoride: SML) The relative molecular mass shall be greater than 70,000 Da Poly[imino(2-methyl-1,4-cyclohexanedi yl)methylene(3-methyl-1,4-cyclohexan ediyl) imino(1,12-dioxo-1,12-dodecanediyl)] PA 0.05 (3,3′-Dimethyl-4,4′-diaminodicyclo hexyl methane: SML) It is only used for reusable food contact materials and articles 4 Polyvinylidene fluoride 24937-79-9 PVDF 5 (vinylindene fluoride: SML) It shall not be used in contact with strongly alkaline substances Poly(vinylidene chloride-co-vinyl chloride) PVDC PVDC ND (1,1-dichloroethene: SML, DL=0.01mg/kg) or 5 (1,1-dichloroethene: QM) 2-propenoic acid, 2-methyl-, methyl ester, polymer with 1,1-dichloroethene and 2-methyl-2-propenenitrile PVDC ND (1,1-dichloroethene: SML, DL=0.01mg/kg) or 5 (1,1-dichloroethene: QM); ND (2-methyl-2-propenenitrile: SML, DL=0.01mg/kg) The service temperature shall not be higher than 121°C. The service temperature shall not be higher than 121°C. The service temperature shall not be higher than 121°C. The service temperature shall not be higher than 121°C. If it contains 1,4-bis (2,3-epoxypropoxy) butane, its mass fraction shall not be higher than 2%, otherwise there is no limit; 1,4-bis (2,3-epoxypropoxy) butane is prone to react with water-based food simulants, and its compliance can be verified by screening migration with residue. The service temperature shall not be higher than 121°C. Oxirane is prone to react with water-based food simulants, and its compliance can be verified by screening migration with residue. ND (in isocyanate, 17; 30 The service temperature shall not be higher than 200°C. Hexamethylene diisocyanate is prone to react with water-based food simulants, and its compliance can be verified by screening migration with residue. […]
