On June 29, 2021, China National Center for Food Safety Risk Assessment (CFSA) requested comments on 8 food-contact materials and articles, including one new food-contact material, one new additive, five food-contact materials for expanded use, and one new disinfectant. The substances and specifications are shown below. 

New Food-Contact Material

1. Silicon dioxide coatings made from the monomers hexamethyldisiloxane and hexamethyldisilazane for use in polyethylene terephthalate (PET) coating. It is subject to a specific migration limit (SML) of 0.05 mg/kg for hexamethyldisiloxane. PET materials and articles coated with this coating may only be filled at room temperature and stored at room temperature for a long period (including T≤70℃, t≤2h or T≤100℃, t≤15min heat filling and pasteurization). This substance may not be used for irradiated food, infant food, or breast milk.

New Additives for Food-Contact Materials and Articles

1. 2-Propenoic acid, polymer with 2,5-furandione and 2-propenamide, sodium salt (CAS No. 1630821-33-8) for use in paper and paperboard at a maximum use level of 0.041% (as dry substance). The maximum permitted residual content (QM) is non-detectable (ND) for acrylamide (non-detect limit (DL) equals 0.01 mg/kg); 6 mg/kg for acrylic acid); 30 mg/kg for maleic acid.

Food-Contact Materials and Articles with Usage Expanded

1. Maltodextin (CAS No. 9050-36-6) for use in adhesives at dossage as necessary.

2. C.I. pigment blue 15 (CAS No. 147-14-8) for use in polylactic acid (PLA) plastics at a maximum use level of 0.7 mg/kg. The use time of PLA plastic materials and products added with this substance may not exceed one hour. In addition, this substance should meet the purity requirements for colorants in GB 9685-2016 Appendix A.

3. C.I. pigment red 254 (CAS No. 84632-65-5) for use in plastics (PLA) at a maximum use level of 1.4 %. The use time of PLA plastic materials and products added with this substance may not exceed one hour. In addition, this substance should meet the requirements of GB 9685-2016 Appendix A for the purity of colorants.

4. Carbon black (CAS No. 1333-86-4) for use in plastics (PLA) at a maximum use level of 1.5%. The use time of PLA plastic materials and products added with this substance may not exceed one hours. In addition, this substance should meet the requirements of GB 9685-2016 Appendix A for the purity of colorants.

5. C.I. pigment yellow 180 (CAS No. 77804-81-0) for use in plastics (PLA) at a maximum use level of 0.5%. The use time of PLA plastic materials and products added with this substance may not exceed one hours. In addition, this substance should meet the requirements of GB 9685-2016 Appendix A for the purity of colorants.

New Disinfectant Raw Materials

1. Peroxyoctanoic acid (CAS No. 33734-57-5) for use on: 1) the surface of tools, equipment or food packaging materials that are in direct contact with food; and 2) tableware, drinking utensils. Disinfectant products containing this substance must indicate the scope of use and method of use on the label and instructions to ensure that the concentration of the substance in the liquid meets the following requirements: 1) when used on food contact surfaces of tools, equipment or food packaging materials that directly contact food, the content of eroxyoctanoic acid may not exceed 122 mg/L; and 2) when used in tableware and drinking utensils, the content of peroxyoctanoic acid may not exceed 52 mg/L.
