Super-slide type biaxial tension polypropylene thin film for easy-quit package retraction tobacco

Abstract

The invention relates to a super-smooth type dual-direction extension polypropylene film used by a retractable cigarette with the package easy to be taken down, comprising a structure of an upper layer, an intermediate layer and a lower layer. The upper layer is added with macromolecular silicone accounting for 1 to 3 percent Mw (namely more than 100,000) of the total weight of polypropylene biopolymer basal material as lubricant and 0.1 to 0.5 percent of cross-link methyl acrylate as anti-adhesiveness agent. The intermediate layer is added with hydrogen oil resin accounting for 10 to 30 percent of the total weight of the polypropylene basal material as erection strengthening agent and 0.2-1.0 percent of alkyl (C14-18) double (2-hydroxyethyl group) amine as anti-static agent. The lower layer is added with macromolecular silicone accounting for 1 to 3 percent Mw (namely more than 100,000) of the total weight of polypropylene triopolymer basal material as lubricant and 0.1 to 0.5 percent of cross-link methyl acrylate as anti-adhesiveness agent. The film has small internal friction and good erection and static electricity prevention, and can enable the cigarette package to be easily taken down from the film.

Description

technical field [0001] The invention relates to a cigarette film, in particular to a super-smooth biaxially stretched polypropylene easy-to-rewind shrinkable cigarette film. It belongs to the technical field of packaging materials. Background technique [0002] Cigarette film has always been a high-end product among biaxially oriented polypropylene products. Due to the fast packaging speed of cigarette machines, the requirements for cigarette films are very high. The film must have: good smoothness of the outer layer, high shrinkage, good optical properties, and good ability to adapt to various cigarette machines. With the improvement of people's living standards, people pay more attention to the outer packaging of products, and the new technology of the packaging industry is also constantly improving. Most of the current cigarette cardboard uses epoxy resin glazing, laser cardboard, and laminated cardboard. And other technologies to increase the appearance, but the inter...

Problems solved by technology

With the improvement of people's living standards, people pay more attention to the outer packaging of products, and the new technology of the packaging industry is also constantly improving. Most of the current cigarette cardboard uses epoxy resin glazing, laser cardboard, and laminated cardboard. and other technologies to increase the appearance, but the internal friction of the cigarette film used before is relatively large. In addition, the above-mentioned cardboard and shrink film packaging have an adsorption effect, and it is difficult for the cigarette pack to withdraw from the film, which brings inconvenience to people.
