At present, there are many food containers and packaging materials allowed in my country, and different types of materials may bring different safety hazards. Plastic is one of the most widely used food packaging materials. Its hazards mainly come from the toxic monomers and pyrolysates remaining in the product. Paper products are also a traditional food packaging material. The raw materials used in the production of food packaging paper may be unclean, and there may be pollution problems such as heavy metals, pesticide residues, and even recycled waste paper as raw materials, causing chemical residues and microbial pollution. Rubber products commonly used in food packaging materials may have potential hazards from synthetic rubber monomers or processing aids. In addition, toxic metal ions may precipitate from metal packaging materials, silicon dioxide may be dissolved from glass materials, and metal oxides may also be dissolved from ceramic glazes.
Irregular production of packaging materials or containers is also one of the main reasons for food safety hazards. At present, most food companies do not allow packaging companies to mark their products, which makes it impossible for consumers to identify the "place of origin" of the packaging. Since consumers cannot supervise, food companies often decide to purchase various processing aids based on whether the cost is low, which causes hidden food safety hazards. For example, plastics are high-molecular polymers, which are formed by polymerization of monomers and initiators under appropriate conditions. In order to improve the processing performance of the plastic and the use performance of the finished product, processing aids such as plasticizers, antistatic agents, smoothing agents, and heat stabilizers should be added in the finished product process. Plastic monomers and processing aids are low-molecular compounds. Under certain medium and temperature conditions, they will dissolve from plastic and transfer to food, thereby contaminating food and endangering human health.
Ink is an indispensable basic material for packaging and printing, and it is also one of the main sources of food contamination. There are two types of traditional packaging printing inks: resin-based and solvent-based. When printing with these two inks, some harmful substances such as heavy metals, organic volatiles and solvent residues will be produced.
