Photocatalytic inorganic antibacterial agent film

Antibacterial mechanism: Currently, the main photocatalytic antibacterial agent is TiO2, which can generate a large number of hydroxyl and oxygen groups on the surface under the action of light. These two groups have strong chemical activity and can cause various microorganisms to undergo organic decomposition, thus possessing antibacterial properties.

Application of photocatalytic inorganic antibacterial agent film. Since the first launch of photocatalytic agents in Japan in 1995, a widely used field is food packaging.

Natural and polymer antibacterial agent films

Other antibacterial agent films include natural antibacterial agent films and polymer antibacterial agent films. Their antibacterial mechanism is through the interaction of charges on molecular chains with microorganisms, thereby inhibiting microbial reproduction and achieving antibacterial effects. At present, chitosan, sorbic acid, and gingerol are mainly used for food packaging.

Composite antibacterial agent film

The effectiveness of composite antibacterial agent films is mainly reflected in the following aspects: extending the antibacterial cycle; Antibacterial properties can be produced at low concentrations; Expand the antibacterial spectrum and inhibit more microorganisms than any single antibacterial agent film.

Organic antibacterial agent film

Antibacterial mechanism: The main mechanism of action of organic antibacterial agents is to gradually enter cells by binding with anions on the surface of microbial cell membranes, or react with thiol groups and other groups on the cell surface, disrupting the synthesis system of proteins and cell membranes, and inhibiting microbial reproduction.
