Antibacterial plastic is a plastic with antibacterial function. It is a type of material that inhibits or kills bacteria, mold, algae, viruses, etc. contaminated on it during use. By inhibiting such Microorganisms survive and reproduce to achieve self-cleaning and durability. Antibacterial plastics are achieved by adding a small amount of antibacterial agents to ordinary plastics. Adding a small amount of antibacterial agent does not change the physical, chemical, mechanical and other properties of the original plastic, while adding special antibacterial functions. At present, the antibacterial agents used in industry in China include silver ions, zinc ions, and organic substances. The following categories are introduced:

Silver ion antibacterial agents. This is a commonly used high-efficiency plastic antibacterial agent. Silver has been used by humans for disinfection and sterilization since ancient times. However, silver ions can easily react with sulfur components in the air, causing discoloration and reducing the antibacterial effect. Controlling the uniform release of silver ions is the key. Currently, the technology of top silver ion antibacterial agents is Controlled by Japanese companies, the products on the market are mainly Japanese companies, such as Japan’s Ze0mic and Japan’s Ishizuka Glass IONPURE series of silver ion antibacterial products. Japan’s Ze0mic uses zeolite carrier silver ions. As antibacterial agents, Japanese Ishizuka Glass uses glass-carrier silver ion antibacterial agents. Both types of carrier antibacterial agents have good silver ion loading, which can ensure sufficient silver ion content and appropriate silver ion release concentration. and speed, and can withstand high temperatures, which can meet the current processing requirements of plastics, coatings, and even ceramics. Both of these antibacterial agents have passed European and American food contact and safety application tests.

Compared with silver ion antibacterial agents, zinc ion antibacterial agents have slightly worse antibacterial activity, but their dispersion, compatibility with plastics, and stability are better. Currently available on the market are American Ochi ZNPT and other products have been registered in the European Union and the United States, meet the requirements of relevant safety regulations, and can be used to export products to Europe and the United States.

There are many types of organic antibacterial and anti-mildew products. Currently on the market are VANQUISH 100, REPUTEX 48, etc. from Aoqi. VANQUISH 100 can be applied to PVC, polyurethane, and silicone resin. , polyolefin, polyester, etc. It has been registered in Europe and the United States.

There is now a new mode of antibacterial agent application: the tag mode. Swiss Sanitized is a pioneer in the application of antibacterial and antifungal agents. Its antibacterial and antifungal application originated from the antibacterial and antifungal application of the US military during World War II. As a result of research, its trademark is Sanitized, which means antibacterial in English. If the products produced by it provide antibacterial agents and achieve the specified antibacterial effect after being tested by it, you can apply to Sanitized Company for a hangtag printed with its registered trademark. Its brand is recognized by the public in Europe and the United States and has antibacterial functions.
