1 Scope
This standard is applicable to manufacture the resin and its blend for food contact plastic materials and products, including unvulcanized thermoplastic elastomer resin and its blend.
2 Terms and Definitions
2.1 Resin
Macromolecular substance synthetized by monomer with low relative molecular mass and other initiators through addition polymerization, condensation polymerization and microbial fermentation polymerization and the natural macromolecular substance through chemical modification, which is also known as polymer.
2.2 Resin blend
Solid polymer material blended by two or more kinds of polymers with same or different chemical structure and physical state through physical and/or chemical method, which is uniform and continuous in macro-level and also known as polymer blend or polymer alloy, each kind of polymer may be regarded as the main structure component or phase of resin material and its product.
