Wear-resisting cigarette film and preparation method thereof

Abstract

The invention relates to a wear-resisting cigarette film and a preparation method of the wear-resisting cigarette film. The wear-resisting cigarette film is composed of a lower surface layer prepared from co-polypropylene and anti-sticking agent, a middle core layer prepared from homo-polypropylene, antistatic agent and nucleating agent, and an upper surface layer prepared from co-polypropylene, modified polyacrylate and nucleating agent. The lower surface layer, the middle core layer and the upper surface layer are sequentially stuck to form a composite layer. The lower surface layer is prepared from, by mass, 96-97% of co-polypropylene and 3-4% of anti-sticking agent, the middle core layer is prepared from, by mass, 94-95% of homo-polypropylene, 1.5-5% of antistatic agent and 0.2-0.3% of nucleating agent, and the upper surface layer is prepared from 60-80% of co-polypropylene, 20-40% of modified polyacrylate and 0.4-0.5% of nucleating agent. Wear of the cigarette film in the product transportation process is reduced, and the loss of enterprises is reduced; and the wear resistance is excellent and exceeds that of imported cigarette films.

Description

Technical field [0001] The invention belongs to the technical field of packaging materials, and in particular relates to a wear-resistant cigarette film and a preparation method thereof. Background technique [0002] Cigarette packaging film, referred to as cigarette film, is a type of BOPP film. As a high-grade BOPP film, smoke film has lower heat sealing temperature, better barrier properties, high transparency, and thickness uniformity than ordinary packaging films. [0003] The performance of cigarette films continues to improve and improve with the demand for cigarette packaging, and technical requirements such as appearance and physical indicators of cigarette films are becoming increasingly homogeneous. As end users of cigarette films, in order to meet consumer needs, cigarette companies are increasingly using dark and bright pigments in cigarette packaging design to improve and beautify the visual effect of cigarette packaging. Therefore, many new problems have eme...

Problems solved by technology

[0006] The invention aims to solve the problem of scratch marks on the surface of the cigarette film due to the friction between the cigarette case and the tobacco rod during the transportation and circulation process, and even whitening and fogging in severe cases, resulting in unclear patterns of the cigarette label , dim color, can not stand the problem of wear and tear, and provide a wear-resistant flower smoke film with simple structure, convenient installation and use, and improved work efficiency and its preparation method
