Ultra-thin stretching film for hands and preparation method thereof

Abstract

The invention discloses an ultra-thin stretching film for hands and a preparation method thereof, wherein the ultra-thin stretching film for hands includes the following specific materials in parts: 5-8 parts of polystyrene, 3-5 parts of polystyrene, 1.5-4 parts of a butadiene-styrene copolymer, 3.5-9 parts of diphenylmethane diisocyanate, 6-12 parts of polyethylene glycol terephthalate, 4-8 partsof polyvinylidene fluoride, 3.5-9 parts of polyvinyl chloride, 2-4.5 parts of polyperfluoroethylene propylene, 7-14 parts of polypropylene, 2-5 parts of polyamide, 4-8 parts of polyethylene glycol terephthalate, 3-6 parts of cellulose acetate, 2-5 parts of carboxymethyl cellulose, 0.4-0.8 part of polyethylene glycol, 1-2 parts of glutaraldehyde, 1.4-3 parts of polycarbonate, 0.5-2.5 parts of a plasticizer, and 0.3-1.2 parts of an auxiliary film-forming agent. The prepared stretching film is light, thin, uniform in thickness, good in tensile strength and not easy to tear; the whole thin film has the advantages of high sealing property, simple processing technology and low raw material cost, and is suitable for quantitative production.

Description

technical field [0001] The invention relates to the technical field of plastic films, in particular to an ultra-thin hand-used stretch film and a preparation method thereof. Background technique [0002] Plastic films are most widely used in the packaging field. Plastic film can be used in food packaging, electrical product packaging, daily necessities packaging, clothing packaging and so on. They have one thing in common, that is, color printing must be performed on plastic films, and multi-layer lamination or vacuum aluminum plating must be performed as food packaging. Therefore, it is required that the surface free energy of the plastic film should be high, and the wet tension should be large, so as to facilitate the firm adhesion of printing ink, adhesive or aluminized layer to the plastic film; in the process of plastic film production, coiling and high-speed packaging, then The surface of the film is required to have a certain friction performance to prevent the film...

Problems solved by technology

[0003] However, the currently used stretched film has poor sealing performance and poor high temperature resistance, and most of them cannot be recycled, which is easy to cause pollution. At the same time, the traditional stretched film is easy to break during the stretching process, and the traditional preparation process is complicated and the cost is high. , therefore, here we propose an ultra-thin stretch film for hand use and its preparation method
