Abstract

The invention discloses a bacteriostatic plastic film, which is prepared from the following raw materials in parts by weight: 7 to 9 parts of tributyl citrate, 110 to 140 parts of low-density polyethylene, 2 to 3 parts of divinyl benzene, 1 to 2 parts of octyl isothiazolinone, 2 to 4 parts of 1H,1H,2H,2H-perfluorodecyltriethoxysilane and 50 to 60 parts of organic modified bacteriostatic agent emulsion. The organic modified bacteriostatic agent emulsion contains chitosan and titanium sol, has good composite bacteriostatic performance, has good compatibility between low-density polyethylene matrixes, and can effectively improve the bacteriostatic performance of a finished film, and the added titanium sol can further improve the mechanical strength and toughness of the finished product, the tensile strength is improved, and the film is good in environmental protection property and excellent in comprehensive performance.

Description

technical field [0001] The invention belongs to the field of plastic films, in particular to a bacteriostatic plastic film and a preparation method thereof. Background technique [0002] Plastic films are films made of polyvinyl chloride, polyethylene, polypropylene, polystyrene, and other resins that are used for packaging and as laminations. Plastic packaging and plastic packaging products account for an increasing share in the market, especially composite plastic flexible packaging, which has been widely used in food, medicine, chemical and other fields, among which food packaging accounts for the largest proportion, such as beverage packaging , quick-frozen food packaging, cooking food packaging, fast food packaging, etc., these products have brought great convenience to people's lives. [0003] However, most of the current plastic films contain toxic plasticizers, and there is little research on antibacterial properties. Contents of the invention [0004] The object...
