What are the problems caused by food packaging safety?

by admin

in September 2004, the random inspection results of food packaging (film) released by the General Administration of quality supervision, inspection and quarantine showed that except for ordinary plastic bags, the sampling inspection failure rate of special food packaging bags was as high as 15%. The most important problems are that the health indicators do not meet the national standards and the physical and mechanical properties of the products are poor. The main reason is that some food packaging (especially plastic products, such as plastic packaging films, bags, barrels, etc.) production enterprises use inferior raw materials to reduce production costs, especially the use of recycled waste plastics, resulting in the content of toxic and harmful substances in food packaging exceeding the standard; The production or printing technology of some food packaging enterprises, especially the quality of solvents, additives and inks used, improper use, unscientific use methods and post-treatment, leads to the content of toxic and harmful substances in food packaging (such as toluene, xylene, lead, etc.) exceeding the standard. The more serious problem is that there are still some people who do not have the conditions for food packaging production to illegally produce and sell “three noes” products. In addition, at present, most of the materials used to package food are plastic products. Under certain medium environment and temperature conditions, polymer monomers and some additives in plastics will dissolve out and transfer a very small amount to food, resulting in hidden dangers to human health. For example, the potential harm of polyvinyl chloride (PVC) fresh-keeping film to human body mainly comes from two aspects: first, the residual amount of vinyl chloride monomer in PVC fresh-keeping film exceeds the standard; Second, diethylhydroxylamine (DEHA) plasticizer is used in the processing of PVC fresh-keeping film. In case of oil or heating, DEHA is easy to release, which is harmful to health after entering the human body with food

according to the investigation of authoritative institutions, in recent years, the safety of food packaging has seriously restricted the export development of China’s food industry. Especially in European and American countries, the standard requirements for food packaging testing are very high, and the restrictions on the residue of harmful substances in food packaging are very strict. In China, many harmful substances in food packaging are excessive, and food exports are often blocked due to packaging problems. According to the Fujian entry exit inspection and Quarantine Bureau, the materials in contact with food exported by China mainly include metal products, ceramic products, plant products and so on. In the first half of 2005, the EU alone issued 36 batches of early warning notices for the above-mentioned products in China, more than three times that of 2004. Among them, metal kitchenware and tableware are mainly due to the excessive migration of nickel, chromium, cadmium and lead, ceramic products are mainly due to the excessive migration of lead and cadmium, plant products and paper products are mainly due to the excessive migration of microorganisms and sulfur dioxide, while other commodities are mainly due to aromatic amines, lead, chromium The migration amount of nickel exceeds the standard
