Antibacterial agents for PET are mainly classified into inorganic antibacterial agents, organic antibacterial agents and compound antibacterial agents. They are widely used in fields such as food packaging, pharmaceutical packaging, textiles, building materials and medical devices.

Antibacterial agents for inorganic coatings are a type of additive that achieves antibacterial functions through inorganic components. They have the advantages of high safety, good heat resistance, and long-lasting antibacterial properties, and are widely used in fields such as construction, medical care, and home appliances. The following is a detailed introduction from aspects such as classification, antibacterial mechanism, and application scenarios:

Fourth, enhance the added value and market competitiveness of products Meeting consumer demands: As consumers' attention to health and quality of life continues to increase, floor moisture-proof MATS with antibacterial and anti-mold functions are more popular in the market.

In UV floor paint,the selection of antibacterial agents is of vital importance. The following are some recommended types of antibacterial agents and their characteristics:

The dry powder anti-mold agent for putty has the characteristics of broad-spectrum antibacterial, long-lasting anti-mold, safety and environmental protection. The following is a detailed analysis: The antibacterial spectrum is broad: The dry powder anti-mold agent for putty has a special effect on various molds, bacteria and yeasts, such as Aspergillus Niger, Aspergillus flavus, Aspergillus discolorius, Trichoderma, Mucor, Trichoderma pellicum

Low toxicity: Zinc is an essential trace element for the human body (the recommended daily intake is about 8-11 mg). A small amount of migration is usually harmless, and its safety is higher than that of silver ions (which may accumulate) or organic antibacterial agents (such as triclosan). Food-grade certification: Complies with the standards of food contact materials in various countries (such as FDA, EU 10/2011, and Chinese GB 4806), and is suitable for long-term use.

Surface coating: Suitable for post-processing antibacterial treatment. The adoption of plasma pretreatment technology to enhance the surface energy of TPE films can improve the adhesion of silver nanoparticle coatings.

In terms of composition, paper glue usually contains nutrients such as starch, protein and oil, which are precisely the "delicacies" needed for the growth and reproduction of mold. For instance, common glue is composed of polyvinyl alcohol, white latex, sodium stearate, talcum powder, urea, ethylene glycol, sucrose, flavoring, water, etc. Among them, components such as sucrose and protein provide rich nutritional sources for mold.

Silver ions/copper ions: Achieve broad-spectrum antibacterial effects by destroying the cell structure of microorganisms and are suitable for plastic handles. When adding, the dosage should be controlled (such as 0.3%-0.8%) to avoid the risk of yellowing or toxicity caused by the precipitation of metal ions. Nano zinc antibacterial agent: Utilizing nano zinc oxide technology, it is safe, environmentally friendly and has a high antibacterial efficiency. It is suitable for food contact grade materials (such as toothbrush handles) and can inhibit Escherichia coli, Staphylococcus aureus, etc.

Driven by the dual impetus of enhanced public health awareness and the iteration of antibacterial technologies, the integration of oil-based coatings and silver-ion antibacterial agents is becoming an innovative direction in fields such as construction, healthcare, and food processing.
