China Solicits Comments on Three New Food-Contact Materials

On October 28, China National Center for Food Safety Risk Assessment (CFSA) solicited comments on three new resins for use in food-contact materials and articles. The substances and specifications are listed below.

• 1,6-Hexanedioic acid, polymer with (E)-2-butenedioic acid and tricyclodecanedimethanol (CAS No. 58891-19-3) is to be cleared for use in coatings and coating layers at a maximum use level of 18% (on a dry weight basis). The specific migration level (SML) is 0.05 mg/kg for tricyclodecanedimethanol. The use temperature for coatings and coating layers containing this substance as a raw material may not exceed 121°C and this substance may not be used in food-contact materials and articles for infant foods. In addition, these restrictions must be labeled in accordance with GB 4806.1.
• Polymer of 1,4-butanediol, 2,2-dimethyl-1,3-propanediol, 1,4-cyclohexanedicarboxylic acid and m-phthalic acid is to be cleared for use in coatings and coating layers at a maximum use level of 30% (on a dry weight basis). The SMLs are 5 mg/kg (as 1,4-butanediol); 0.05 mg/kg (2,2-dimethyl-1,3-propanediol); 5 mg/kg (1,4-cyclohexanedicarboxylic acid); and 5 mg/kg (as m-phthalic acid). The use temperature for coatings and coating layers containing this substance as a raw material may not exceed 130°C. In addition, these restrictions must be labeled in accordance with GB 4806.1.
• Polymer of butanediol-1,4, tricyclodecanedimethanol and dimethyl terephthalate (CAS No. 490017-22-6) is to be cleared for use in coatings and coating layers at a maximum use level of 59% (on the coating formula basis). The SMLs are 7.5 mg/kg (as terephthalic acid); 5 mg/kg (as 1,4-butanediol); and 0.05 mg/kg (4,8-tricyclo[5.2.1.0 2,7]decanedimethanol). The use temperature for coatings and coating layers containing this substance as a raw material may not exceed 121°C and this substance may not be used in food-contact materials and articles for infant foods. In addition, these restrictions must be labeled in accordance with GB 4806.1.
