Abstract

The invention belongs to the field of antibacterial and antiviral polyolefin packaging bag special materials, and particularly relates to an antibacterial and antiviral express packaging bag special material and a preparation method thereof. The preparation method comprises the following steps: mixing polyolefin powder, an antioxidant, an auxiliary antioxidant, a halogen absorbent and an antibacterial agent in a high-speed stirrer for 2-3 minutes to obtain a mixture, and extruding and granulating the mixture by a double-screw extruder to obtain the antibacterial and antiviral express packaging bag special material. Polyolefin materials such as polypropylene and polyethylene have permanent antibacterial, mildew-proof and antiviral properties, and an express packaging bag produced by using the special material also has permanent antibacterial, mildew-proof and antiviral properties, so that the diffusion of pathogens is effectively prevented.

Description

technical field [0001] The invention belongs to the field of special materials for antibacterial and antiviral polyolefin packaging bags, in particular to a special material for antibacterial and antiviral express packaging bags and a preparation method thereof. Background technique [0002] As the new crown epidemic continues to spread around the world, the new crown virus has caused the risk of overseas imports in China by attaching to transported goods, commodities and other carriers. At the same time, bacteria and viruses will also spread through the process of commodity trading, mailing and transportation, endangering people's health. As people pay more and more attention to their health, an antibacterial and antiviral express bag will have important applications in commodity trading and cargo transportation. [0003] With the development of the Internet age, online shopping and overseas purchasing agents are on the rise, and goods are often transported by express deli...
