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
Even with these disinfection and sterilization methods, the disinfection and sterilization effects cannot be maintained for a long time

Abstract

A durably antibacterial plastic container is prepared from the nano-class granular mixture of plastics and metal ions chosen from Ag, Cu, Ti, Zn and Ni, and the raw materials of plastics through proportionally mixing and injection moulding.

Description

technical field [0001] The invention relates to a long-acting antibacterial plastic container and a manufacturing method thereof, which are suitable for loading food, human medicine or other medical supplies. It belongs to the technical field of plastic containers. 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. However, the inside and outside of food and medical plastic packaging containers are extremely susceptible to infection and bacteria. 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 plastic packaging for food and medicine can easily cause people to cross-spread bacteria and affect people's health. [0003] Existing plastic packaging containers for various foods and medicines...
