Common food packaging materials include glass, metal, paper, plastic, and composite packaging materials. Among them, for food packaging plastic materials, various factors need to be comprehensively considered in terms of hygiene and safety, such as the safety of the resin itself, the safety of the additives used, and the applicable amount.
There are many types of plastic materials that can be used for food packaging, and countries generally approve their use in the form of regulations or standards. The United States is mainly regulated by the FDA, and the European Union also mainly determines whether it can be used for food contact by regulating the list of plastic synthetic raw materials. In our country, it is mainly regulated by the former Ministry of Health, and the form is mainly regulated through standards and announcements.
China's sanitary standard plastic resins include polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS), polyethylene terephthalate (PET), and unsaturated Polyester (UP), polycarbonate (PC), vinylidene chloride-vinyl chloride, nylon (PA). The corresponding standards are GB 4803-1994 'Sanitary Standards for Polyvinyl Chloride Resins for Food Containers and Packaging Materials', GB 9691-1988 'Sanitary Standards for Polyethylene Resins for Food Packaging', and GB 9693-1988 'Polypropylene Resins for Food Packaging' Hygienic Standard ', GB 9692-1988' Sanitary Standard for Polystyrene Resin for Food Packaging ', GB 13114-1991' Sanitary Standard for Polyethylene Terephthalate Resin for Food Containers and Packaging Materials ', GB13115-1991' Food Hygienic Standard for Unsaturated Polyester Resin for Containers and Packaging Materials and Its FRP Products, GB 13116-1991, Hygienic Standard for Polycarbonate Resins for Food Containers and Packaging Materials, GB 15204-1994, Vinylidene Chloride for Food Containers and Packaging Materials -Hygienic Standard for Vinyl Chloride Copolymer Resin ', GB 16331-1996' Sanitary Standard for Nylon 6 Resin for Food Packaging Materials '.
On the basis of resin hygiene standards, some sanitary standards for food-contact molded products have also introduced national hygiene standards, namely polyvinyl chloride molded products, composite food packaging bags, polypropylene molded products, polyethylene molded products, and polystyrene. Molded products, melamine-formaldehyde (melamine) molded products, polyethylene terephthalate molded products, unsaturated polyester resins and glass fiber reinforced plastic products, polycarbonate molded products, PVC bottle gaskets, composites Food packaging bags, acrylonitrile-butadiene-styrene molded products, acrylonitrile-styrene molded products, etc. These standards are GB 9681-1998 'Sanitary Standards for Polyvinyl Chloride Molded Products for Food Packaging', GB 9683-1988 'Sanitary Standards for Composite Food Packaging Bags', GB 9687-1988 'Sanitary Standards for Polyethylene Molded Products for Food Packaging', GB 9688-1988 'hygienic standard for polypropylene molded products for food packaging', GB 9689-1988 'hygienic standard for polystyrene molded products for food packaging', GB 9690-2009 'melamine-formaldehyde molded products for food containers and packaging materials hygiene Standards ', GB 13113-1991' Sanitary Standards for Polyethylene Terephthalate Molded Products for Food Containers and Packaging Materials ', GB 13115-1991' Unsaturated Polyester Resins for Food Containers and Packaging Materials and Their FRP Products Hygiene Standard ', GB 14942-1994' Sanitary Standards for Polycarbonate Molded Products for Food Containers and Packaging Materials ', GB 14944-1994' Sanitary Standards for PVC Bottle Cap Gaskets and Granules for Food Packaging ', GB 16332-1996' Sanitary Standards for Nylon Molded Products for Food Packaging Materials ', GB 17326-1998' Sanitary Standards for Rubber Modified Acrylonitrile-Butadiene-Styrene Products for Food Containers and Packaging Materials ', G B 17327-1998 'Sanitary Standards for Acrylonitrile-Styrene Products for Food Containers and Packaging Materials'.
