Contact material detection

         With the increasing concern of the whole society on food safety issues, food safety issues caused by food contact materials (FCMs) such as food containers, packaging materials, and kitchenware have also attracted the attention of all sectors of society. Countries around the world, especially the European Union countries and the United States, have made very strict regulations on food contact materials. Products that are exported to the European Union and the United States must pass the corresponding test certification and obtain a qualified product test report. ". Therefore, a credible third-party test report has become a gold medal "pass" for Chinese exports to enter the European Union and the United States and other international markets.

        In China, from January 1, 2008, the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China (AQSIQ) has implemented a market access system for food packaging, containers, tools, and other products, and requires manufacturers to carry out corresponding testing and certification. Products must obtain a production license and be marked The "QS" logo can only be sold on the market or used. The first batch of food packaging, containers, tools and other products that implemented the market access system were 39 products in 3 categories. Food packaging, containers and tools of other materials will also implement the market access system one after another.

Contact material testing:

The relationship between the EU and food contact materials and products according to the above framework. We can know that the materials that have been clearly legislated in the EU can generally be divided into: (1) plastic (2) rubber (3) ceramics (4) cellulose film supplement: EU Directive 94/62 / EC stipulates that the total content of Pb, Cd, Hg, Cr6 + is less than 100 ppm. 1: Plastics according to 2002/72 / EC. The items we test are: a. Comprehensive migration test (divided into: water, ethanol, acetic acid, olive oil migration test) 2: PVC items tested according to 78/142 / EEC A: vinyl chloride monomer test 3: cellulose film tested according to 93/10 / EEC are a: monoethylene glycol (MEG) b: diethylene glycol (DEG) c: free formaldehyde d: toluene 4: Ceramics tested according to 84/500 / EEC ----- a: heavy metals (lead and cadmium) 5: rubber nipples tested according to 93/11 / EEC ----- a: N -Nitrosamine b: N-nitrosamine production

German food contact materials testing items exported to Germany not only comply with the requirements of the EU directives, but also comply with Articles 30 and 31 of the German Food Sanitation Law (LFGB). Specific test items are: 1: EU Directive requires test item 2: German regulations for products in contact with food a sensory test (odor test and taste test) b: peroxide value test 3: German regulation (LFGB) relative to EU directive Added test section 3.1: PE plastic products required testing: a: chromium, vanadium, zirconium content testing 3.2: PS, ABS, SAN, Acrylic plastic products required: a: total organic volatiles 3.3: PP plastic products required testing: a : Chrome vanadium zirconium content test 3.4: PA, PU plastic products required test: a: aromatic amine migration test 3.5: PET plastic products required test: a: zinc lead content test 3.6: Silicone Rubber silicone rubber products required test: a: organic volatilization Total amount c: Organic tin compound content test (seven items) 3.7: Rubber, TPR, TPE rubber product requirements a: Formaldehyde dissolution test b: Zinc, lead content test d: Aromatic amine migration test 3.8: Paper paper product requirement a : Pentachlorophenol test (PCP) b: Dissolution of heavy metals (lead, cadmium, chromium, nickel) test c: Antibacterial component migration test d: Formaldehyde content test e: Paper with color －Additional azo dye test 3.9: Baking paper requirements for baking paper products a: Appearance b: Thermal stability c: Antibacterial ingredient migration test d: Polychlorinated biphenyls test (PCBs) e: Formaldehyde dissolution test 3.10: Wood Wood product requirements Test: a: Pentachlorophenol test (PCP) 3.11: Requirements for non-stick coating products (non-stick pan) test: a: phenol dissolution test b: formaldehyde dissolution test c: aromatic amine dissolution test d: hexavalent Chromium dissolution test e: Trivalent chromium dissolution test f: Ammonium perfluorooctanoate test 3.12: Ceramic, glass, enamel products required test: a: Heavy metal dissolution test 3.13: Metal, alloy and electroplated products required test: a: Heavy metal dissolution ( Lead, cadmium, chromium, nickel) test.
