4 Natial Food Safety Standard Plastic Resin used in food-ctact 1 Scope This standard applies to the resin and resin blends used for the producti of food ctact plastic materials and products, including n-vulcanized thermoplastic elastomer resin and its blends. 2 Terms and definitis 2.1 Resin It refers to the macromolecular substances AND the chemically modified natural macromolecules, also known as polymers synthesized by the polymerizati reacti such as additi polymerizati, cdensati polymerizati and microbial fermentati polymerizati, using the momers with lower relative molecular mass and other starting materials as the main materials. 2.2 Resin blends It refers to the macroscopically uniform solid polymer materials as formed by physical and/or chemical mixing of two or more polymers having the same or different chemical structures and physical states, with each polymer being used as the main structural compents or phases of the resin material and its product, which is also known as polymer blends or polymer alloys. 3 Basic requirements Food ctact plastic resin shall comply with the requirements of GB Technical requirements 4.1 Raw material requirements Raw materials for the producti of the food ctact plastic resin shall ensure that under normal and expected cditis of use, it shall not harm to human health.
