Description

Technical Field

[0001] The utility model belongs to the technical field of antibacterial plastics, and particularly relates to an antibacterial plastic product. Background Art

[0002] Plastics are macromolecules formed from monomers through polyaddition or polycondensation reactions. They have a moderate deformation resistance, somewhere between that of fibers and rubber. They are composed of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. Plastics are lightweight, chemically stable, and rust-resistant; they offer excellent impact resistance, good transparency and abrasion resistance, excellent insulation, low thermal conductivity, and generally good formability and colorability, resulting in low processing costs. These properties of plastics contribute to their important applications in both life and industry. Plastic products are widely used to hold and package food, beverages, cosmetics, and pharmaceuticals. In practice, microorganisms, primarily bacteria, are highly susceptible to attaching to the interior and exterior of plastic containers for food, beverages, and pharmaceuticals. These microorganisms can cause food and pharmaceutical spoilage, shorten the shelf life of packaging, and impact public health. With the advancement of technology, people are increasingly concerned about food safety, necessitating antimicrobial treatment of plastics to impart certain antimicrobial properties.

[0003] Existing plastics used in food and pharmaceutical packaging or containers are typically sterilized during the molding process. Traditionally, sterilization of molded products has required the use of agents such as alcohol, bleach, sodium hypochlorite, and hydrogen peroxide, or ultraviolet light, microwave irradiation, or high-pressure steam sterilization. However, these agents, such as alcohol, bleach, sodium hypochlorite, and hydrogen peroxide, can easily leave residual chemical components harmful to the human body, while ultraviolet light, microwave irradiation, or high-pressure steam sterilization are expensive and increase costs. The applicant has discovered that existing methods for sterilizing plastic products suffer from high costs, unsatisfactory sterilization results, and short duration. Utility Model Content
