On Nov. 17, 2021, Beijing Product Quality Supervision and Inspection Institute issued a notice to solicit public opinions for "GB 4806.10-xxx Paints and Coatings in Contact with Foodstuffs (Draft)". Any comment can be submitted via email email@example.com before Dec. 12, 2021.
Major Revisions Revealed by the Draft
This revision proposes to include all the paints and resins for coatings from the current GB 4806.10-2016 and all notifications issued by National Health Commission (NHC) from 2016-2021, like the latest NHC Notice No. 9 of 2021. Therefore, the application scope was extended correspondingly. Compared with the current version, paints and coatings for paper are newly included in the application scope.
Physicochemical Indicators for Coatings
The draft further improves the physicochemical indicators. For epoxy coatings with different disphenol epoxy derivatives, the corresponding three indictors are set. If the epoxy coating contains BADGE, the overall migration shall not more than 9 mg/kg or 9 mg/6dm2. If it contains BADGE·HCI, then the overall migration shall not more than 1 mg/kg or 1 mg/6dm2. If it contains BFDGE or NOGE, then the coating is forbidden for using.
According to the current version, the labeling of coatings and articles shall conform to GB 4806.1. Now the draft further specifies that coating materials and articles shall also be marked with the substance names of the substrate and coating following an order from the outer layer to the layer in direct contact with food.
Use Requirements of Basic Raw Materials for Paints and Coatings
Same as the current version, the Annex A of the draft provides a list for basic raw materials allowed to be used in paints and coatings in contact with foodstuffs and relevant use requirements. In addition, the draft clarifies that substances with molecular weight greater than 1,000 Da formed by polymerization or other means from monomers, other initiators, basic polymers and other raw materials in this list are also allowed to be used as basic raw materials for paints and coatings for food contact.
