Problems solved by technology

[0002] At present, the plastic films commonly used in the market for food packaging are made of ordinary polyethylene, such as the refrigerator fresh-keeping packaging of fruits and vegetables commonly used in households. It is also necessary to suppress metabolism to the greatest extent under the premise of maintaining the normal metabolism of fruits and vegetables, delay their maturation and aging, and effectively prevent microbial growth. Gas and water are sealed in the bag, causing bacteria to grow rapidly and fruits and vegetables to rot quickly

Abstract

An antibacterial, antistaling and ultraviolet-resistant plastics contains polyolefin plastics, montmorillonite, negative-ion microparticles, ultraviolet-resistant microparticles, photocatalyst nanoparticles, antibacterial inorganic microparticles, and titanate or silane coupling agent. Its film is prepared from said plastics, polyethylene and assistant. Its advantage is high effect.

Description

technical field [0001] The invention relates to a plastic film, in particular to a nano-material antibacterial, fresh-keeping and anti-ultraviolet plastic. Background technique [0002] At present, the plastic films commonly used in the market for food packaging are made of ordinary polyethylene, such as the refrigerator fresh-keeping packaging of fruits and vegetables commonly used in households. It is also necessary to suppress metabolism to the greatest extent under the premise of maintaining the normal metabolism of fruits and vegetables, delay their maturation and aging, and effectively prevent microbial growth. The gas produced and the water content are all sealed in the bag, causing bacteria to grow rapidly, and fruits and vegetables to rot quickly. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the plastic films commonly used on the market for food packaging in the prior art are all made of ordinary polyethylen...
