Problems solved by technology

Most foods are rich in nutrients and high in water content, so they are easily contaminated by microorganisms and cause spoilage, which greatly shortens the shelf life of food
[0004] The existing food packaging materials have no antibacterial effect, and the materials are not strong and easy to be damaged, so they cannot be widely used

Abstract

The invention relates to an antibacterial hygienic packaging material for foods and belongs to the technical field of packaging materials. The antibacterial hygienic packaging material includes a fresh-keeping antibacterial layer as an inner layer, a middle thermal insulation layer and a barrier layer serving as an outer layer. The barrier layer is prepared from high-density polyethylene, allyl thiocyanate, plasticizer and a cross-linking agent. The thermal insulation layer is prepared from filler, polycaprolactone, calcium carbonate and bamboo carbon powder; and the fresh-keeping antibacterial layer is prepared from soybean oil, wheat fiber, konjac sol, silicon oxide powder, dioctyl maleate, an antibacterial agent and a silane coupling agent. The antibacterial hygienic packaging materialis easy to produce, the raw materials are rich, and the cost is low. On the premise of ensuring characteristics of original packaging materials, through microbial decomposition, no pollution is causedto the environment, and the antibacterial hygienic packaging material has a certain antibacterial effect and is high in mechanical property, safe, nonhazardous and high in environmental friendliness.

Description

technical field [0001] The invention relates to a component of a packaging material, in particular to an antibacterial and hygienic packaging material for food, and belongs to the technical field of packaging materials. Background technique [0002] Modern human life is inseparable from packaged food, and providing safe and hygienic packaged food is the most basic requirement for food manufacturers. For a long time, food packaging mostly adopts traditional packaging methods and packaging materials, such as fresh-keeping packaging, modified atmosphere packaging and multi-layer composite material packaging. In recent years, with the improvement of people's living standards, food tends to be diversified, convenient and hygienic. Food often requires long-distance transportation and long-term storage. In this case, the requirements for food packaging technology are getting higher and higher. [0003] Microorganisms are small in size, various in variety, rapid in reproduction an...
