Abstract

The invention discloses an efficient antibacterial fresh-keeping film material and relates to the field of high polymer materials. the efficient antibacterial fresh-keeping film material is composed of the following raw materials (by weight): 20-25 parts of polyethylene, 10-16 parts of starch and polyvinyl alcohol, 3-7 parts of chitosan, 3-7 parts of xylan, 2-4 parts of rosin resin, 4-8 parts of glycerinum, 2-4 parts of aluminium oxide, 3-5 parts of glass fiber, 2-5 parts of rosin glyceride, 1-2 parts of nano-silicon power, 1-3 parts of nano Ag-carrying antibacterial powder, 2-4 parts of ascorbic acid and 2-5 parts of an antibacterial aid. The invention also discloses a preparation method of the material. The preparation method comprises the following steps: preparation of a film substrate mixture; preparation and extrusion of an antibacterial agent; and coating process. The formula of the invention is reasonable. A prepared fresh-keeping film has good strength, good water resistance, good heat resistance, excellent tearing strength and excellent antibacterial property. By the use of the fresh-keeping film, shelf life of preserved goods can be prolonged. The fresh-keeping film has high safety, is harmless to human body, and has high production efficiency and long service life. In addition, the preparation method of the fresh-keeping film is simple and easy to operate.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a high-efficiency antibacterial fresh-keeping film material. 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. According to the different materials used and the addition of plasticizers, plastic wrap is divided into various types, which can be applied to different occasions. Preservative film has been favored by people for its convenience, economy and attractive appearance. [0003] The cling film on the market is roughly divided into two categories, one is ordinary cling film, which is suitable for refrigerator preservation; the o...
