Antibacterial Mechanism Of PET Healthcare Bottle

Antibacterial mechanism of PET healthcare bottle: The main mechanism of action of organic antibacterial agents is to gradually enter cells by combining with anions on the surface of microbial cell membranes, or react with groups such as sulfhydryl groups on the surface of cells, destroy the synthesis system of proteins and cell membranes, and inhibit the reproduction of microorganisms.

The composite antibacterial agent currently used in food packaging, the organic antibacterial agent triazine antifungal agent on the Japanese market and the compound antibacterial agent triazine antibacterial agent compounded by pyridine antibacterial agent, its antibacterial effect has improved by 3 -4 times.

Antibacterial mechanism of photocatalytic inorganic antibacterial agent thin film: the current photocatalytic antibacterial agent is mainly TiO2, which can generate a large number of hydroxyl radicals and oxygen free radicals on the surface under the action of light. These two free radicals have strong chemical activity. , can cause various microorganisms to decompose organically, so it has antibacterial properties. Application of photocatalytic inorganic antibacterial thin film. Since photocatalytic preparations were launched in Japan in 1995, one of the current widely used areas is food packaging.

The antibacterial mechanism of natural and polymer antibacterial agent films is through the interaction of charges on the molecular chain with microorganisms, thereby inhibiting the reproduction of microorganisms and playing an antibacterial effect. At present, chitosan, sorbic acid, and turmeric root alcohol are mainly used in food packaging.

The effect of the composite antibacterial agent film is mainly reflected in the following aspects: prolonging the antibacterial cycle; producing antibacterial properties at low concentrations; broadening the antibacterial spectrum and inhibiting more microorganisms than any single antibacterial agent film. Nano-TiO2 can be added to inorganic silver-based antibacterial agents in food packaging films to solve the problem of slow antibacterial effects of silver-based antibacterial agents.

Healthcare plastic bottle antimicrobial packaging is the most promising part of food active packaging. After some food is sterilized for aseptic packaging or vacuum packaging, it is difficult to achieve the original aseptic effect if the packaging of the food is damaged during transportation or is stored after opening. In this case, it is most beneficial to choose antibacterial film packaging, which can continuously release antibacterial agents to inhibit the growth of microorganisms, ensure food safety and extend the shelf life of food. Let our consumers enjoy the quality of life.
