GB13116-91 Hygienic Standard for Polycarbonate Resin for Food Containers and Packaging Materials

GB14942-94 Hygienic Standard for Polycarbonate Molded Products for Food Containers and Packaging Materials

GB/T5009.99-2003 Analytical method of hygienic standard for polycarbonate resin used in food containers and packaging materials

my country's hygienic standard stipulates that the dissolution amount of phenol (distilled water, refluxed for 6h) in carbonate resin and molded products is not more than 0.05mg/kg. The titration method is used to quantitatively calculate the free phenol in the solution.


The EU Regulation 2002/72/EC stipulates that the migration limit of bisphenol A in plastic food contact materials is 3mg/kg. The EU uses liquid chromatography to detect the migration of bisphenol A (the detection limit is 0.2-0.7 mg/kg).


The U.S. Food and Drug Administration (FDA) stipulates that bisphenol A can be used as a raw material for food contact materials. The BPA (1993) specifies that the maximum acceptable dose or reference dose is 0.05 mg/


The Food Sanitation Law stipulates that the dissolution limit of bisphenol A in polycarbonate food containers is 2.5 mg/kg.
