Food safety is very important for people. Basically every food has a package, so the material and quality of the packaging bag also determines the safety of a food. Let's discuss the impact of various materials on food safety and some solutions:

1、 Effects of harmful substances in food packaging on food safety
1. The impact of paper packaging materials on food safety
A part of paper packaging materials are produced by waste paper. In the process of collecting raw materials, there will be some moldy paper. After production, a large number of molds and pathogenic bacteria will be produced, which will cause food spoilage. At the same time, recycled waste paper may contain harmful substances such as lead, cadmium, polychlorinated biphenyls, which can cause dizziness, insomnia, forgetfulness and even cancer.
Some food factories do not use special ink for food packaging when using paper food packaging materials. Most of these non special inks contain organic solvents such as toluene, which may cause benzene solvents in foods to exceed the standard. Benzene solvents are highly toxic. If they penetrate into the skin or blood vessels, they will endanger the hematopoietic function of human body, damage the nervous system of human body, and even lead to leukemia Health.
2. The impact of plastic packaging materials on food safety
Additives, such as adhesives, are often used in the production of plastics. The adhesive is mainly composed of aromatic isocyanate. The plastic bag made of this material can form aromatic amine after high temperature cooking, which is a carcinogen. Plastic is easy to recycle and is often used repeatedly. If the recycled plastic materials are directly used in food packaging, it will have a great impact on food safety.
The recycling channels of plastic packaging are complex, and it is difficult to clean the residual harmful substances on the recycling containers. Some manufacturers add a large amount of paint in the recycled plastics, resulting in large amount of paint pigment residue, causing food pollution.
Due to lax supervision, some medical waste plastics are recycled, which will become a considerable food safety hazard. In addition, stabilizers, plasticizers and colorants added in the process of production and processing are easy to migrate out of plastic and cause secondary pollution due to their poor quality, which is also one of the factors endangering food safety.
3. The influence of metal packaging materials on food safety
Metal packaging containers can be divided into two categories, one is non coated metal, the other is coated metal. The main safety problem of uncoated metal packaging container is the dissolution of toxic and harmful heavy metals; the safety problem of coated metal packaging container is mainly the dissolution of free phenol, free formaldehyde and toxic monomer in the coating on its surface. Iron and aluminum are two kinds of metal packaging materials mainly used in the market, among which tinplate, Wuxi steel plate, aluminum and aluminum foil are the most commonly used. In iron products, zinc will migrate to food after zinc coating contacts with food, thus causing food poisoning; the main problem of aluminum products is that aluminum materials contain lead, zinc and other elements, excessive intake will cause chronic accumulation poisoning.
2、 Solutions to food packaging safety problems
1. Establish and improve food packaging material safety related laws and regulations
At present, most of the laws and regulations in China's food packaging industry were formulated in the early 1990s, which basically did not involve benzene residue, migration and some corresponding indicators of heavy metal content. Therefore, the relevant departments should update and improve the relevant safety regulations and standards of food packaging materials, such as the composition standards of additives, adhesives and inks, food labeling system, market access system of food packaging materials and appliances, and establish and improve the safety assurance system of food packaging materials.
2. Develop new packaging materials and packaging technology
Because of the high cost and poor safety factor of traditional packaging materials, functional packaging materials have become a hot topic in western countries. The United States, Japan and the European Union have invested a lot of money and manpower in this field. According to the prediction of experts, in the future, the packaging bags produced by intelligent packaging technology will account for 20% ~ 40% of the total number of food packaging. It is the general trend for food packaging materials to be functional, intelligent and environmentally friendly. The research and development of new packaging materials must be the focus of future development, such as modified atmosphere packaging, antibacterial packaging, nano composite packaging materials and so on, through the new packaging materials and technology to improve the safety of food packaging.
3. Improve the food packaging testing system
Due to the different molecular structure, various additives and molding process of packaging materials, the food packaging materials show great differences, so the detection of food packaging materials is more complex. We can establish a perfect food packaging testing center to test the performance characteristics of various packaging materials according to national standards. At the same time, the detection technology should be improved to find a fast and efficient detection method to improve the detection level of residual monomers, heavy metals and other toxic and harmful substances in food packaging.
