Problems solved by technology

At present, the packaging materials used in food, medicine and other products are mainly such polyolefin materials, but these packaging materials will still fog up in the film at high temperature, and this anti-fog film does not have antibacterial effect
And the antibacterial film in the prior art has certain antibacterial property, but simple antibacterial film then does not have anti-fog effect
Due to the large water content of vegetables and fruits, the temperature changes greatly during storage, transportation and sales, which will produce a layer of opaque water mist on the inner layer of the packaging bag, making it difficult for users to see the goods in the bag; At the same time, the existence of water mist will cause the reproduction of fine bacteria, which will affect the antibacterial effect of the film, and cannot play a good role in the field of vegetable and fruit packaging.

Abstract

The invention relates to the field of plastic packaging, and concretely relates to a high-performance novel antibacterial and antifogging film. The high-performance antibacterial and antifogging filmincludes a polyolefin resin film, an antibacterial and antifogging film and a printing layer; the polyolefin resin film is sandwiched between the printing layer and the antibacterial and antifogging film; and the thickness of the high-performance antibacterial and antifogging film is 10-45 [mu]m.

Description

technical field [0001] The invention relates to the field of plastic packaging, in particular to a novel high-performance antibacterial and anti-fog film Background technique [0002] With the improvement of consumers' requirements for food safety, freshness of packaging, flavor and convenience, as well as the huge changes in food production, distribution, storage and consumption, it is urgently required that food packaging no longer only play a role in protecting and marketing products. Instead of a passive role, it gradually plays an active and active role. The market competition of fresh food depends to a certain extent on the scientificity and feasibility of packaging. The traditional plastic packaging film used for fresh food packaging will be fogged due to changes in the external environment or water vapor generated by the metabolism of fruits and vegetables. Lead to spoilage of fresh food. Anti-fog and antibacterial packaging film can significantly improve the appe...
