Abstract

The invention relates to a plastic composite film, in particular to an anti-bacterial medical protective film. The anti-bacterial medical protective film comprises an upper-layer film, an intermediate-layer film and a lower-layer film which are sequentially adhered together, wherein the intermediate-layer film comprises the following ingredients: 10-40 parts of linear low-density polyethylene, 10-40 parts of low density polyethylene and 20-80 parts of metallocene intermediate density polyethylene or metallocene high density polyethylene; the upper-layer film comprises the following ingredients: 10-30 parts of metallocene intermediate density polyethylene or metallocene high density polyethylene, 32-52 parts of low density polyethylene, 30-50 parts of linear low density polyethylene, 1-10 parts of an anti-bacterial agent, 0.5-0.8 part of zeolite and 0.01-0.2 part of a slipping agent. The anti-bacterial medical protective film provided by the invention has a favorable bacterium and fungus killing function, is safe and nontoxic, only needs to be disinfected for a short time before use, or, is directly used without disinfection, and meanwhile, has relatively high transparency.

Description

technical field [0001] The invention relates to a plastic composite film, in particular to an antibacterial medical protective film and a preparation method thereof. Background technique [0002] Hospital articles are divided into high-risk, medium-risk, and low-risk categories according to the degree of harm to the human body after contamination by articles. The high-risk articles refer to medical equipment and articles that will cause serious harm after being contaminated by microorganisms, such as surgical instruments and supplies. , Infusion and blood transfusion equipment, etc. The principle of the hospital is that all high-risk items must be sterilized by high-efficiency disinfection methods to make their sterilization index reach 10. -6 (Even if the survival probability of microorganisms is less than 10 -6 ). Disinfectants commonly used in high-efficiency disinfection methods include glutaraldehyde, formaldehyde, peracetic acid, hydrogen peroxide, ethylene oxide, a...
