Plastic food packaging bags processing and matters needing attention

plastic food packaging bags processing note

the content of the food hygiene law than measures for the administration, 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, pipelines, conveyor belt and plastic packaging materials and the use made 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. Window 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 refers to the monolithic and composite packaging materials of bottles, barrels, tray, roll film and bag, the roll of film packaging film, bag sealing membrane and membrane. Manufacturing food flexible packaging, composite packaging materials should strictly carry out the measures for the management of all of the manufacturer.

plastic packing bags of food processing must be heated this checkpoint, and at the time of the heated plastic cracking, oxidation and degradation, deterioration problems, therefore, when the resin processing plastic film or bags, to join in the resin antioxidant, heat stabilizer and other additives. Some packaging film bag as a result of the need of packaging technology and mechanical or contents also requires high anti-static, prevent dewing, smooth, so also want to join the antistatic agent, antifoggant, lubricants, opening agent such as additives. All of these additives, the first thing to the GB15139 'food * toxicology evaluation process of 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. So for FRP products must have the corresponding health standards, its purpose, is to prevent disorderly use and abuse of additives, packaging and food contact directly to better safeguard the materials with high performance of health *.
