The latest release of 4 new national standards for food contact coatings, silicone rubber, etc!
Time：
2025-09-26
The latest release of GB 4806.10-2025 "Coatings and Coatings for Food Contact Materials and Products", GB 4806.16-2025 "Silicone Rubber Materials and Products for Food Contact", and two national standards for the determination of food contact materials and products!
Introduction to 4 new standards
GB 4806.10-2025 "National Food Safety Standard - Coatings and Coatings for Food Contact Materials and Products"
Implementation date: September 2, 2026
This standard is a revised version of GB 4806.10-2016, applicable to coatings and coatings for food contact materials and products [definition: coatings intended to be applied to food contact materials and products, directly or indirectly in contact with food but whose components may transfer to food, and the coatings (films) formed by them].
Compared to the original standard, this standard has mainly revised the following aspects:
Modified the standard name;
Modified the scope;
Revised terminology and definitions;
Modified basic requirements;
Modified the requirements for raw materials;
Modified physical and chemical indicators;
Modified the requirements for migration testing;
Modified label identification;
Modified Appendix A.
GB 4806.16-2025 "National Food Safety Standard - Silicone Rubber Materials and Products for Food Contact"
Implementation date: September 2, 2026
This standard replaces the relevant requirements for silicone rubber in GB 4806.11-2016 and is applicable to silicone rubber materials and products used in food contact. [Definition: Materials and products that have been or may be in contact with food or food additives under expected use conditions, or whose components may be transferred to food, mainly composed of silicone elastomers formed by crosslinking and curing reactions of polydimethylsiloxane polymers and hydrophobic silica and other substances].
Compared to the original standard, this standard has mainly revised the following aspects:
Modified the scope;
Revised terminology and definitions;
Modified the requirements for raw materials;
Modified sensory requirements;
Modified physical and chemical indicators and added volatile substances;
Added other technical requirements;
Modified the requirements for migration testing;
Modified label identification requirements;
Modified Appendix A;
Added the determination of volatile substances in Appendix B.
GB 31604.21-2025 "National Food Safety Standard - Determination of Migration of Benzoic Acid, Phthalic Acid, and Benzoic Acid in Food Contact Materials and Products"
Implementation date: March 2, 2026
This standard is a revised version of GB 31604.21-2016. This standard specifies the liquid chromatography method for determining the migration amount of benzoic acid, 1,2-phthalic acid (also known as phthalic acid), 1,3-phthalic acid (also known as isophthalic acid), 1,4-phthalic acid (also known as terephthalic acid), 1,3,5-phthalic acid (also known as trimellitic acid), 1,2,4-phthalic acid (also known as trimellitic acid), and 1,2,3-bhthalic acid (also known as phthalic acid) in food contact materials and products.
Compared with the original standard, the new standard maintains liquid chromatography as the analytical method, but makes the following three main modifications:
Change the standard name from the original 2016 version of "Determination of migration of terephthalic acid in food contact materials and products" to the current "Determination of migration of benzoic acid, phthalic acid, and trimeric acid in food contact materials and products";
The scope has been modified to include the determination of migration amounts of benzoic acid, 1,2-phthalic acid, 1,3-phthalic acid, 1,3,5-phthalic acid, 1,2,4-phthalic acid, and 1,2,3-bhthalic acid;
Revised the analysis steps and result presentation.
GB 31604.64-2025 "National Food Safety Standard - Determination of Migration of Citrate and Sebacate Compounds in Food Contact Materials and Products"
Implementation date: March 2, 2026
This standard is a newly established standard. This standard specifies the methods for determining the migration of triethyl citrate, di-n-butyl sebacate, tributyl acetyl citrate, di (2-ethylhexyl) sebacate, diisooctyl sebacate, and di (2,2,6,6-tetramethyl-4-piperidine) sebacate in food contact materials and products. Gas chromatography-mass spectrometry (GC-MS) was used to detect the migration of two citric acid esters and four sebacic acid esters in plastic, rubber, adhesive, coating, paper and other products used in food contact. Citrate and sebacic acid esters have become the main new plasticizers to replace traditional ortho phenyls.
This standard is applicable to food simulants such as water, 4% acetic acid, 10% ethanol, 20% ethanol, 50% ethanol, 95% ethanol, olive oil, and isooctane. The method detection limit is 0.1-0.2 mg/kg and the quantification limit is 0.2-0.5 mg/kg, which can meet the practical requirements for compliance testing of citrate and sebacic acid ester compounds in GB 9685-2016.
