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 invention relates to the field of preservative films, and particularly discloses an antibacterial preservative film and a preparation process thereof. The antibacterial preservative film sequentially comprises a first base layer, a first stabilizing layer, a connecting layer, a second stabilizing layer and a second base layer in a thickness ratio of (2-3): (1-2): (1-3): (1-2): (2-3), wherein ingredients in the first base layer, the first stabilizing layer, the connecting layer, the second stabilizing layer and the second base layer interact with one another; the preparation process of theantibacterial preservative film comprises the following steps: respectively mixing ingredients in the first base layer, the first stabilizing layer, the connecting layer, the second stabilizing layerand the second base layer, and then carrying out tape casting extrusion, cooling, trimming, edge leading and rolling to obtain the antibacterial preservative film. The product can be used for wrappingfood, fruits and vegetables so as to delay deterioration of the food, fruits and vegetables, and has the advantage of efficient antibiosis; in addition, the preparation process has the advantages ofbeing simple and clean.

Description

technical field [0001] The application relates to the field of fresh-keeping film, more specifically, it relates to an antibacterial fresh-keeping film and a preparation process thereof. Background technique [0002] Plastic wrap is a kind of plastic packaging product, usually made of ethylene as the masterbatch through polymerization reaction, mainly used in microwave oven food heating, refrigerator food preservation, fresh and cooked food packaging and other occasions, in family life, supermarkets, hotels and restaurants It is widely used in the field of industrial food packaging. [0003] The plastic wrap can wrap the food, so that the food is convenient to store, and it can also prevent the moisture in the food from dissipating, so that the food does not lose its original taste; in addition, the plastic wrap also helps the food to avoid the infection of external bacteria. However, the current plastic wrap does not have antibacterial effect, and there are a large number ...
