Safety hazards of food plastic packaging bags The basic component of plastic is polymer resin, and various additives will be added to improve the performance of plastic. Plastic products as food packaging materials, low cost, plasticity, can meet the requirements of a variety of packaging materials. Many food processing industries will choose it as a food packaging material. But some substances in plastic packaging materials can pollute food and affect food safety. There are custom plastic food packaging. It is worth noting that the recent popularity of recycled plastics has two aspects. On the one hand, it reduces the waste of resources. On the other hand, the process and method of recycling are difficult to control, so there will be residues of toxic substances and contaminated food. 2. Safety risks of food paper packaging bags The raw materials of food packaging paper are mainly straw pulp and wood pulp. Due to root causes, pesticide residues are sometimes unavoidable. If not handled cleanly, food will be contaminated. Problems also arise in the process of recycling waste paper. Most technologies can only remove ink and pigments, but not harmful substances. Recycle moldy paper, mold can also remain on the paper packaging. In addition, substances added to paper packaging can also bring harmful substances.

Due to insufficient attention to the problem of food packaging, there is no ink for food packaging in the market at present. The inks commonly used at present are organic solvent gravure inks, which contain toluene and xylene. The ink is diluted in food packaging, and the diluted solvent contains benzene. The residue left by this solvent on food packaging not only exceeds the standard, but also causes food contamination. The pigments and dyes used in ink contain heavy metals such as lead and cadmium, which can cause heavy metal pollution of food. 3. Safety risks of metal products packaging Metal materials are widely used in food packaging and have many advantages. A variety of metal containers made of metal materials can better cut off external influences on food and ensure the freshness of food. In addition, metal materials are easy to recycle many times. But metal packaging also has obvious disadvantages. With the decrease of chemical stability, metallic substances are affected by external factors and tend to react. High acid alkaline food can not use metal packaging. Iron container, aluminum food packaging, stainless steel food packaging is the common metal food packaging. But the packaging poses other safety risks. People eat aluminum packaged food for a long time, the body will accumulate lead, zinc and other metals, cause chronic poisoning. Stainless steel food packaging contains a lot of nickel, high temperature will volatilize the unstable substances in food, and even cause carcinogens, has a great harm to human health.
