Foreword
The standard replaces GB 4803-1994 “Hygienic standard for polyvinyl chloride
resin used as food container and packaging material”, GB 9691-1988 “Hygienic
standard for polyethylene resin used as food packaging material”, GB 9692-
1988 “Hygienic standard for polystyrene resin used as food packaging material”,
GB 9693-1988 “Hygienic standard for polypropyrene resin used as food
packaging material”, GB 13114-1991 “Hygienic standard for polyethylene
terephthalate resin used as food containers and packaging materials”, GB
13116-1991 “Hygienic standard for polycarbonate resin used as food containers
and packaging materials”, GB 15204-1994 “Hygienic standard of vinylidene
chloride-vinyl chloride copolymer resins for food containers and packaging
materials”, the resin part of GB 13115-1991 “Hygienic standard for unsaturated
polyester resin and glass fiber reinforced plastics used as food containers and
packaging materials”, GB 16331-1996 “Hygienic standard of nylon 6 resin for
food packaging material”, AND the relevant parts on plastic resin in the
“Announcement on the publication of the list of 107 resins available for food
packaging material including polyhexamethylene adipamide” (No.23
announcement in 2011, original Ministry of Health).
This standard, as compared with the above standards and announcements, has
the following main changes.
- MODIFY the standard name into “National Food Safety Standard - Plastic
Resin used in food-contact”;
- MODIFY the scope;
- ADD terms and definitions;
- ADD the basic requirements;
- ADD the raw material requirements;
- MODIFY the physical and chemical indicators;
- ADD the general requirements for migration test;
- ADD the marking requirements;
- ADD Appendix A.
National Food Safety Standard
Plastic Resin used in food-contact
1 Scope
This standard applies to the resin and resin blends used for the production of
food contact plastic materials and products, including non-vulcanized
thermoplastic elastomer resin and its blends.
2 Terms and definitions
2.1 Resin
It refers to the macromolecular substances AND the chemically modified natural
macromolecules, also known as polymers synthesized by the polymerization
reaction such as addition polymerization, condensation polymerization and
microbial fermentation polymerization, using the monomers 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 components or phases of the resin material and its
product, which is also known as polymer blends or polymer alloys.
3 Basic requirements
Food contact plastic resin shall comply with the requirements of GB 4806.1.
4 Technical requirements
4.1 Raw material requirements
4.1.1 Raw materials for the production of the food contact plastic resin shall
ensure that under normal and expected conditions of use, it shall not harm to
human health.
Appendix A
Plastic resin allowed to use and use requirements
A.1 Table A.1 specifies the plastic resin allowed for use AND the use
requirements.
A.2 The specific migration total limit [SML (T)] and SML (T) grouping number in
Appendix B of GB 9685-2016 apply to this standard.
