Problems solved by technology

At present, sterilization packaging film has accounted for 65% of the foreign packaging film market, but the price is too high for Chinese people to bear
Most of the packaging materials for dairy products in my country are made of ordinary polyolefin, which has a fresh-keeping period of only 3-6 days and a short antibacterial and fresh-keeping time, which seriously restricts the development of China's dairy industry. Therefore, research and development has a long-term Effective antibacterial food flexible packaging materials become necessary

Abstract

The invention discloses a food flexible packing material with antibacterial function, and application thereof. The food flexible packing material chooses nanometer zinc oxide particles and a surface modifier to produce inorganic compound antibacterial agent, and adds the nanometer zinc oxide particles into PE resin for producing antibacterial masterbatch by utilizing the characteristics of persistent bactericidal action, efficient antibacterial effect and high temperature resistance and the like of the nanometer zinc oxide particles so as to process and produce the food flexible packing material with antibacterial function and products thereof; wherein, the PE resin accounts for 95-97%, the nanometer zinc oxide accounts for 3-5% and the surface modifier accounts for 0.1-0.3% (by weight). The antibacterial flexible packing film for dairy food and the products thereof, which are produced by the flexible packing material, have the characteristics of persistent bactericidal action, efficient antibacterial effect, high barrier property, shielding property, high temperature and the like, thus greatly prolonging the freshness date and shelf life of foods. The products have wide use and can be used for the packing of all dairy food, beverage, seasoning, meat, marine product and other foods.

Description

technical field [0001] The invention relates to a food packaging material and its application, more specifically, to a food plastic polyethylene resin soft packaging material with antibacterial function and its application. Background technique [0002] With the development and progress of society, people pay more and more attention to protecting their health, and pay more and more attention to the aseptic freshness of food packaging, especially in the field of dairy products. With the rapid development of China's dairy industry, the The requirements for dairy packaging films are also increasing. Antibacterial packaging can not only solve the problem of food spoilage caused by microorganisms, but also greatly reduce food loss. At present, the requirements for packaging materials and packaging levels are getting higher and higher in the market, among which the development of multi-functional fresh-keeping and aseptic packaging materials with high impermeability is the fastes...
