Food contact materials
Food contact materials (FCM) refer to food packaging, food utensils, auxiliary materials, equipment, tools and other materials and products in contact with food. Common food contact materials include plastics, metals, glass, ceramics, fiber products, etc.
Acrylic is commonly known as plexiglass, chemical name is polymethyl methacrylate (PMMA). The polymers obtained by polymerization of acrylic acid and its esters are collectively referred to as acrylic resin, and the corresponding plastics are collectively referred to as polyacrylic acid plastics, among which polymethylmethacrylate is the most widely used. Acrylic is one of the most excellent synthetic transparent materials with the most suitable price. In recent years, it has been gradually used in the production of high-end food packaging materials, such as wine pourer, kitchen condiment box, plastic plate and so on, which are popular with consumers and widely used.
Application of acrylic in food contact materials
In view of PMMA’s high transparency, high hardness and relatively low price, the main food contact materials in the circulation field include food packaging containers and tools
Food packaging containers: acrylic snack box, acrylic fruit plate, acrylic plastic cup, acrylic condiment can, acrylic sealed can, acrylic transparent flat top oil bottle and other food containers;
Food packaging tools: acrylic cake rack, acrylic multi-layer food display rack, acrylic art drink straw, acrylic plastic ice shovel, acrylic plastic food clip, etc.
Safety risk and related standards of acrylic as food contact material
The application of acrylic in food contact materials is more and more extensive, and its safety risk has gradually attracted public attention. Whether adding methyl methacrylate additives or PMMA products, there may be monomer residues due to incomplete polymerization or aging and degradation for a period of time.
At present, in view of the use of methyl methacrylate as initial reaction monomer or additive, China’s announcement on the list of 107 resins that can be used as food packaging materials (Ministry of health Announcement No. 23, 2011) stipulates that the migration amount of methyl methacrylate is ≤ 6mg / kg, The migration of maleic acid used for polyester plasticizer is less than 30mg / kg. For the method of methyl methacrylate monomer in polymethylmethacrylate, refer to Sn / T 3183-2012 determination of methyl methacrylate in polymethylmethacrylate (PMMA) as food contact materials by gas chromatography.
SMQ food testing institute is always ready for you
In recent years, SMQ food testing institute has been committed to the research of food packaging material safety testing, and has accumulated rich testing experience, and has undertaken the research on plastic bottles (barrels), microwave tableware, acrylic related food contact materials, thermoplastic elastomers, microwave tableware, etc. from Guangdong Provincial Bureau and Shenzhen Municipal Bureau Risk monitoring items of food contact materials such as food packaging paper and inner coating of metal cans. Gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-mass spectrometry (LC-MS) can be used to quickly detect bisphenol A, plasticizer, solvent residues and other related items in food contact materials. Enterprises in need are welcome to submit for inspection.
