Abstract

The invention discloses an antibacterial type nano-fiber-based fresh-keeping film which is composed of the following raw materials by weight: 1-2 parts of sodium tripolyphosphate, 130-150 parts of polyethylene, 1-2 parts of mannan, 10-14 parts of nano crystalline cellulose, 4-7 parts of cellulose acetate propionate, 10-14 parts of methyl ester nylon acid, 1-2 parts of 8-hydroxyquinoline, 0.7-1 part of Diisopropylethanolamine, 5-8 parts of Triethylene Glycol Di-2-ethylhexoate, 3-4 parts of sucrose acetate isobutyrate, 5-7 parts of allylpolyethyleneglycol, 10-20 parts of diatomite, 40-50 parts of a bacteriostatic water dispersion and 2-3 parts of Hydroxyethylidene-1,1-diphosphonic acid, after the added diatomite is modified by esterification, the diatomite is well compatible with a polymer matrix, and effectively improves the stability strength of a finished film, and the antibacterial type nano-fiber-based fresh-keeping film has good toughness, good antibacterial activity, good use safety and excellent comprehensive performance.

Description

technical field [0001] The invention belongs to the field of films, and in particular relates to an antibacterial nanofiber-based fresh-keeping film and a preparation method thereof. Background technique [0002] Plastic wrap is a kind of plastic packaging product commonly used by people to keep fresh food, and now many families cannot do without them. Microwaves will be used to heat food, as will storing food in the refrigerator. Most of the cling films currently on the market are the same as the commonly used plastic bags. They are all made of vinyl masterbatch. According to the different types of vinyl masterbatch, the cling film can be divided into three categories. The first is polyethylene, referred to as PE. This material is mainly used for food packaging. The film we usually buy for fruits and vegetables, including semi-finished products purchased in supermarkets, is made of this material; the second The first is polyvinyl chloride, referred to as PVC, this materia...
