The source of traffics in food packaging materials

Poisonous and harmful chemical substances in food packaging materials of migration is one of the important ways to cause food contamination. Different countries for food packaging materials migration quantity have different rules. Food packaging material amount of migration is divided into the overall migration and specific migration. Overall migration quantity ( OML) : from the final materials or products in the migration process of analog to food or food material. Specific transfer amount ( SML) : from the final food or food materials or products in the migration to simulate the process of certain substances. According to the total amount of migration, migration of certain quantity can be found that the definition of total migration quantity value should be equal to all specific transfer amount of non-volatile components combined. Therefore, as long as prove that the determination of total migration quantity value is less than the specific migration quantity of some non volatile matter, can prove that the components conform to the requirements of the limited amount of specific migration. From the domestic and foreign reports, the harm of food packaging materials mainly material internal residual poisonous and harmful chemical contaminant migration and dissolution and cause food contamination. Packaging materials may contain harmful substances mainly has the following categories: 1, additives: in order to improve the processing of polymer materials and the use of performance, need to add various additives in polymerization process, due to some additives or additive degradation has certain toxicity to human body. The commonly used processing AIDS are: plasticizer, stabilizer, antioxidant, antistatic agent, colorant, etc. 2, printing ink, ink is direct contact with plastic packaging materials, so the safety of the ink is particularly important. Changzhou food packaging manufacturers to use all the ink is environmental protection, to ensure that the printing effect at the same time, the safety of the product in the first place. 3, raw material, composite material itself may have some poisonous substances, such as the low molecular weight polymers in PET, PVC in vinyl chloride and so on, need to do the evaluation on its amount of precipitation and detection.
