The Impact Of Food Packaging Materials On Food Safety

With the development of society and the improvement of people's living standards, food packaging presents a trend of diversification, and the types of packaging materials are increasing. Food packaging provides convenience to people's lives to a certain extent. However, food safety accidents caused by packaging materials occur from time to time.

To this end, it is necessary to pay attention to and improve the safety of food packaging materials. Food packaging materials refer to products used for packaging and holding food or food additives and coatings that directly contact food or food additives. It can be seen that the quality of food packaging materials directly affects food safety. So, from the perspective of the main packaging materials used, what effects do they have on food safety?

1. Food plastic packaging materials

Plastic is the most widely used food packaging material. The unsafe hazard lies in the migration of monomers, formaldehyde, toluene and other compounds in the resin. In addition, the use of additives added in the production process, such as stabilizers, colorants, plasticizers, etc., cause certain compounds to migrate into food, affecting food safety.

2. Food paper packaging materials

Paper is the oldest and most traditional packaging material. In the papermaking process, chemicals such as impermeable agents, bleaching agents, dyeing agents, etc. need to be added to the pulp, and some chemical substances will migrate into the food. Antifungal agents or formaldehyde used in processing can also be dissolved from paper products.

3. Food metal packaging materials

Metal packaging mostly uses aluminum foil, iron foil and tin-plated cans. When using aluminum foil, it is rarely used alone, and is mostly used together with plastic film. The surface of the metal can is mostly coated with plastic. Therefore, certain compounds in heavy metals and additives migrate into food and affect food safety.

Fourth, food glass container packaging materials

Glass is also a molten material of inorganic substances, the main component of which is SiO2-Na2O. Depending on the type of glass, there is an eluate from the raw material.

In addition, the coloring of food packaging materials requires the use of metal salts. If the heavy metals migrate into the food, it will also affect the food safety, and there is a hidden danger of insecurity.

In order to do a good job in the safe packaging of food, it is necessary to establish sound food packaging safety regulations and standards, develop new packaging materials and packaging technologies, and improve the corresponding testing system, so as to reduce the safety problems caused by food packaging materials and maximize food packaging. Important function - to protect food.
