Antibacterial plastic bottle cover and manufacturing process thereof

Abstract

The invention relates to the technical field of plastic bottle covers and in particular relates to an antibacterial plastic bottle cover and a manufacturing process thereof. The antibacterial plastic bottle cover is formed by performing injection molding on mixed plastic particles and plastic raw materials; the mixed plastic particles are prepared by uniformly mixing one or more than two of nano-scale metal ion silver, copper, iron, zinc and nickel into the plastic raw materials and fully mixing; the effective antibacterial time can be synchronous with the service life of the antibacterial plastic bottle cover. The invention also provides a process for manufacturing the antibacterial plastic bottle cover. According to the process for manufacturing the antibacterial plastic bottle cover provided by the invention, the antibacterial plastic bottle covers of various specifications and various shapes can be processed and molded, the antibacterial plastic bottle covers have long-term antibacterial sterilization effects, equipment and sterilization and disinfection agents needed by sterilization and disinfection are not required, passive sterilization is changed into active sterilization, the cost of sterilization and disinfection is saved, secondary pollution of disinfectants on the environment can be avoided, and environmental protection is realized.

Description

technical field [0001] The invention relates to the technical field of plastic bottle cap processing, in particular to an antibacterial plastic bottle cap and a manufacturing process thereof. Background technique [0002] At present, plastic containers are widely used in industrial production and people's daily life, especially in the packaging of various food and pharmaceutical products. Plastic bottle caps are used as supporting products for plastic containers. The packaging of pharmaceutical products plays an important role. In practical application, the inside and outside of food and medical plastic containers are very easy to infect and breed bacteria, and the inside and outside of the matching plastic packaging bottle caps are also very easy to infect and breed bacteria. [0003] Infection of bacteria in plastic packaging for food and medicine will lead to deterioration of food and medicine or shorten the validity period of the packaging. Infection of bacteria outside...

Problems solved by technology

When using alcohol, bleaching powder, sodium hypochlorite and hydrogen peroxide for disinfection, it is easy to leave chemical components harmful to the human body. Use ultraviolet rays, microwave irradiation or high-pressure steam for disinfection and sterilization. These disinfection and sterilization methods are expensive. increase cost
