Packaging bags and packaging rolls are the most common containers and the most basic. Safety issues are focused on, affecting physical safety. There are a lot of microorganisms and bacteria in the air that are invisible to the naked eye. If the sterilization effect of the container is not obvious, it will cause secondary pollution. How to sterilize food packaging roll film can really effectively protect food safety. The sterilization process of ozone is a biochemical oxidation reaction. Ozone first acts on the cell membrane, causing damage to the components of the cell membrane, resulting in metabolic disorders. Ozone continues to penetrate the cell membrane to destroy lipoproteins and lipopolysaccharides in the cell membrane, changing cell permeability and leading to cell death. Use ozone sterilization to sterilize production equipment and products, and improve the quality and grade of food packaging film. Ultraviolet sterilization is the use of ultraviolet wavelengths to destroy the molecular structure of DNA or RNA in bacteria and viruses, forming growth cell death and regenerative cell death, to achieve the effect of sterilization and disinfection. The two methods are usually the most commonly used sterilization methods. In general, the UV penetration ability is relatively poor, and the cost of the two methods is similar. It is best to use the ozone sterilization method for the food packaging roll film, in order to increase the sterilization area and achieve better sterilization effect. .
