The hygiene standards of food packaging materials in China

by:Qusheng     2020-11-12
Have laws and regulations on food and its packaging material has already been in our country and the corresponding health standards, there are two: one is the food hygiene law of the People's Republic of China, the second is the measures for the administration of food in plastic products and raw materials. 'Food health law is promulgated by the State Council, and the measures for the administration is the issued by the ministry of health. These two are mandatory law, in violation of the provisions of the it shall bear legal responsibility. The content of the food hygiene regulations than management approach is much more broad, is a comprehensive law, which is professional, only refers to the plastic products and raw materials, limit the scope of control in contact with all kinds of plastic tableware, food containers, production management, conveyor belt and plastic packaging materials and the use of synthetic resins and additives. Plastic tableware refers to the spoon, spoon, chopsticks and so on short time contact food but to the repeated use of the plastic products. Container refers to the barrel, plastic bottles, POTS, cups, etc costumes food products. Production line refers to the material in the process of food processing, especially liquid food or drink through the pipeline, also should including filling and storage. Conveyor belt refers to the delivery of food raw materials to processing equipment of the carrier, and packaging materials refers to the monolithic or composite bottles, barrels, tray, roll film and bag, the volume of membrane including film, bag sealing membrane and membrane. All manufacturing food soft composite packaging materials manufacturers should strictly carry out the measures for the administration. These two aspects of health norm of raw materials and products. The hygiene standards of raw materials, have GB9691 hygiene standards of food with polyethylene resin, GB9692 hygiene standards of food with polystyrene resin and GB9693 hygiene standards of food with polypropylene resin. In the three resin, polyethylene and polypropylene ethylene dosage the biggest, dosage of polystyrene at least, and will be less and less. In addition to the three resins abroad, as well as polyester ( PET) , nylon ( PA) Other health standard of the resin. The hygiene standards of raw materials, has the heavy metal content, evaporation residue, potassium permanganate consumption, decoloring indicators such as regulation, and the index of abroad, and aldehyde content, heavy metals such as cadmium, arsenic and mercury content of phenol and amine content, etc. Products in terms of health standards, with GB9687 food packaging polyethylene molding product hygiene standards, GB9688 food packing polypropylene molding product hygiene standards, GB9689 'food packaging poly acrylic health standard' moulded and GB9683 composite food packaging hygiene standards. The front three health standard project, moulded evaporation residue, potassium permanganate consumption, heavy metal content of specific indicators, and the fourth 'the composite food packaging hygiene standards,' added 2 amino toluene content shall not be greater than zero. Index of 004 mg/L. Plastic processing must be heated this checkpoint, and synthetic resin and plastic when heated exist in cracking, oxidation and degradation, deterioration problems, therefore, when processed into plastic containers with resin or film, to join the antioxidant, heat stabilizer and other additives. Some membrane also antistatic, prevent dewing, demanding a smooth, so adding antistatic agent, antifoggant, smooth opening agent additives, etc. All of these additives, the first thing to the GB15139 'food safety toxicology evaluation procedure of the test, prove just can use non-toxic, but there is also an added amount limit. So, in the products, these can be extraction of low molecular weight material, namely evaporation residue, or can be the oxidation, potassium permanganate consumption, cannot exceed the prescribed amount, can't use more than. For FRP products, therefore, must have the corresponding health standards, its purpose, is to prevent abuse and misuse of additive, is to ensure better direct food packaging and contact materials with high health and safety performance. Before six of the seven criteria above, only from the resin raw material to the hygiene standards, its products are without compound packing materials hygiene standards. Composite material is more complicated than the raw materials for resin and resin products, because it pass printing ink, adhesive for compound, can make packaging material. So, in our country and developed GB9683 composite food packaging hygiene standards. Adhesive of trace substances harmful to health, also affects the health of the whole system performance, and the two amino toluene is a kind of carcinogenic substance, must be strictly controlled, so the rules cannot be greater than zero. 004mg/L。 According to the data conversion, namely contents shall not be greater than about four over one billion in the index. In fact, in addition to the hygiene standards of the project and index, composite packaging materials in the standard in our country, there is also a residual solvents shall not be greater than 10 mg/M2, GB10004 and GB10005, for example, recently raised the toluene residue may not be greater than 3 mg/M2. This is because of peculiar smell of packaging materials in recent years more and more strict and potential toxicity. So, in addition to limit its residues, followed by the development of water-based ink and adhesive, alcohol soluble ink and adhesive, and solventless adhesives such as new products, the purpose is to safeguard the composite material has higher purity, health and safety performance. In order to control the health security of food containers and packaging materials, in our country and developed GB9685 'food containers, packagings YongZhuJi use of health standard', in the additives of health standard, provides additives, solvents, adhesives, etc. 17 categories, 58 kinds of concrete material and the name of the highest usage. In a composite packaging materials, in addition to resins, additives, as well as ink and adhesive, there is no separate health standards, also have no unified national product standards, only the production enterprise of the enterprise standard
