Food packaging machines should pay attention to food safety

The hazards caused by food packaging materials can be divided into direct contact and indirect contact from the contact point of view, and can also be divided into frequent contact and accidental contact. For example, the kitchen countertop and food will have accidental contact; the paper packaged food will be put into the insulation bag, and there will be indirect contact with the inner wall of the insulation bag. These forms of exposure may provide opportunities for the migration of hazardous substances. From the perspective of production and processing, the hazards of food packaging can also be divided into two aspects. First, the hazards caused by the material itself. The vast majority of packaging materials are chemical products, and the materials themselves have hidden dangers. For example, monomers cracked when plastics are high temperature, heavy metals in metal materials, etc. may be transferred to food through packaging. Second, the harm caused by illegal additives in the production process. For example, in order to make children's tableware brighter and reduce costs, some unscrupulous traders will use industrial-grade color masterbatches to color products. Because there are a lot of harmful substances in industrial-grade color masterbatches, such as aromatic amines, heavy metals, etc., if ingested There will be serious consequences in the body. For another example, some manufacturers use recycled paper to produce food packaging paper, and at the same time use fluorescent whitening agents to improve the whiteness of the paper. Studies have shown that fluorescent whitening agents entering the human body will greatly increase the risk of cancer in the human body. Potential offending additives are also phthalates, a type of plasticizer widely used in toys, food packaging materials, medical blood bags, hoses, detergents, and more. Once it dissolves and enters the human body, it will have an effect similar to estrogen on the human body, interfere with human endocrine, endanger the male reproductive system, increase the risk of breast cancer in women, and at the same time endanger the liver and kidneys of children, causing precocious puberty in children. How about the status of food packaging at home and abroad In terms of consumer awareness, domestic consumers pay more attention to the food itself, focus on shelf life, food labels, etc., and lack understanding of the safety of food packaging. Foreign consumers have strong safety awareness, they will consciously purchase food packaging products with food safety labels, and use them in strict accordance with the warnings on the packaging products; when they find problems with food packaging, consumers usually Take the initiative to contact the manufacturer or local regulatory authorities for inquiries, questions and even complaints, and even use legal means to protect their own interests.
