Problems solved by technology

However, the current plastic wrap does not have antibacterial effect, and there are a large number of bacteria, molds, viruses and other microorganisms in the human living environment, so the plastic wrap will be contaminated with microorganisms during use, so that the wrapped food is also contaminated with microorganisms. In addition, food It will also mold itself to produce microorganisms
[0004] In the above-mentioned related technologies, because the plastic wrap does not have antibacterial effect, the microorganisms on the surface of the food will multiply rapidly, which will affect the preservation time of the food and is not conducive to human health.

Abstract

The application relates to the field of fresh-keeping film, and specifically discloses an antibacterial fresh-keeping film and a preparation process thereof. An antibacterial fresh-keeping film sequentially includes a first base layer, a first stable layer, a connecting Layer, the second stable layer and the second base layer, the ingredients in the first base layer, the first stable layer, the connecting layer, the second stable layer and the second base layer interact; the preparation process of the antibacterial fresh-keeping film is: the first base layer , the first stabilizing layer, the connecting layer, the second stabilizing layer and the ingredients in the second base layer are mixed, and then the antibacterial fresh-keeping film is made by tape extrusion, cooling, trimming, leading, and winding. The product of the application can be used to wrap food, fruits and vegetables to delay the deterioration of the food, fruits and vegetables, and has the advantage of high-efficiency antibacterial; in addition, the preparation process of the application has the advantage of being simple and clean.

Description

Technical field [0001] This application relates to the field of plastic wrap, and more specifically, it involves an antibacterial plastic film and its preparation process. Background technique [0002] Waste film is a plastic packaging product, usually made of ethylene to be prepared by polymerization, mainly for microwave food heating, refrigerator food preservation, fresh and delicious packaging, in family life, supermarket store, hotel restaurant and Industrial food packaging fields are widely used. [0003] Wrap can be wrapped in food, so that the food is convenient, and it can prevent the water in the food, so that the food does not lose its fresh flavor; in addition, plastic wrap also helps food from external bacteria infection. However, the current plastic wrap does not have a bacteriostatic effect, and there is a large number of bacteria, mold, viruses such as bacteria, mold, viruses in the human living environment, so the plastic film is contaminated with microorganisms,...
