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 cover is prepared from the granular mixture of raw plastics and the nanoparticles of metal chosen from Ag, Cu, Ti, Zn and Ni and the raw plastics through proportional mixing and injection moulding. Its advantages are long antibacterial time and low cost.

Description

technical field [0001] The invention relates to a long-acting antibacterial plastic container cover 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. As a supporting product for plastic containers, plastic container covers are also used in various food and 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 container cover are also very easy to infect and breed bacteria. Infection of bacteria in plastic packaging for food and medicine will lead to deteri...
