Introduction and Application Directions of Antibacterial Agents for pet
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. The following is a specific analysis:
I. Types of Antibacterial Agents for PET
Inorganic antibacterial agent
With metal ions such as silver ions and zinc ions as the main active components, they are loaded onto inorganic carriers through physical or chemical methods.
It has the characteristics of good heat resistance, high safety and long-lasting antibacterial effect.
Nano-silver antibacterial agent is a glass-based nano-inorganic antibacterial agent. It appears as a white ultrafine powder and can effectively inhibit and kill bacteria. It has high safety, excellent heat resistance, and broad-spectrum antibacterial effects. It is suitable for films and injection molded parts made of various materials such as PP, PE, and PET. It has excellent inhibitory and killing effects on over 600 types of bacteria, including Escherichia coli, Staphylococcus aureus and Candida albicans, and its antibacterial function can be maintained for more than 8 years.
Organic antibacterial agent
It mainly consists of organic compounds such as quaternary ammonium salts and phenols, and achieves bactericidal effects by interfering with the metabolic processes of bacteria or destroying their cellular structures.
It has the advantages of fast sterilization speed and low usage concentration, but its heat resistance and durability are relatively poor.
Compound antibacterial agent
By combining inorganic antibacterial agents with organic antibacterial agents and integrating the advantages of both, the antibacterial effect and persistence can be enhanced.
It has the characteristics of broad-spectrum antibacterial property, high efficiency and safety.
Ii. Application of Antibacterial Agents for PET
Food packaging
Antibacterial PET materials can effectively inhibit the growth of bacteria, molds and other microorganisms, thereby extending the shelf life of food.
It is suitable for the packaging of ready-to-eat foods, condiments, beverages and other foods that need to be preserved for a long time.
It has excellent sealing and barrier properties, which can prevent external factors such as oxygen and moisture from eroding food, maintaining the freshness and nutritional value of food.
Pharmaceutical packaging
Antibacterial PET materials can prevent drugs from reacting with oxygen, moisture and other substances in the air, thereby protecting the quality of the drugs.
Ensure that the medicine is not contaminated during storage and transportation to maintain its efficacy and safety.
Textiles
Antibacterial PET materials can be used in close-fitting textiles such as underwear, socks and towels to enhance the antibacterial performance of the products, maintain cleanliness and hygiene, and reduce the occurrence of diseases such as skin diseases.
It is also commonly used in sportswear, such as sports socks and sports pants. These products need to have good moisture absorption and sweat-wicking performance as well as antibacterial properties to maintain the comfort and health of athletes.
Building materials
Building materials such as floor and wall coatings made of antibacterial PET materials can inhibit the growth of bacteria, improve the hygiene level of the living environment, and help prevent respiratory diseases and skin diseases, etc.
Antibacterial door handles, antibacterial window sills and other building components are particularly important in public places and medical institutions, which can reduce the risk of cross-infection.
Medical devices
The use of antibacterial PET materials on surgical instruments can reduce the risk of infection and ensure the safety of patients.
Antibacterial PET materials can also be used for the packaging of medical devices to ensure that they are not contaminated during storage and transportation.
Other fields:
Antibacterial PET materials can also be used in the interiors of transportation vehicles (such as antibacterial seats, steering wheel covers, curtains, etc.) and household appliances (such as antibacterial refrigerator door handles, antibacterial washing machine inner drums, etc.), etc., to enhance the hygiene performance of products and reduce cross-infection
