Cigarette logo permeable printing packaging film for replacing cigarette paper carton and preparation method of packaging film

Abstract

The invention discloses a cigarette logo permeable printing packaging film for replacing a cigarette paper carton and a preparation method of the packaging film. The packaging film comprises an outer layer, an inner layer and a core layer between the inner layer and the outer layer, wherein the core layer consists of polypropylene homopolymer, hydrocarbon resin and master batch; both the outer layer and the inner layer are made from low-temperature heat-seal films, and each low-temperature heat-seal film consists of master batch and a copolymer. The film disclosed by the invention is prepared by adopting a multi-layer coextrusion two-way stretching method, and the heat-seal temperature of the packaging film is 60-95 DEG C; when the cigarette carton is packaged through the packaging film, the inner layer is free from heat seal with a small box packaging outer layer, and simultaneously has a printable function. By using the packaging film disclosed by the invention, exiting cigarette paper carton packaging can be completely replaced, the adhesive consumption amount and the paper consumption are reduced in cigarette packaging, the packaging cost of a cigarette factory is reduced, and simultaneously purposes of energy conservation and environmental protection can be achieved.

Description

technical field [0001] The invention belongs to the technical field of packaging, and further belongs to the technical field of cigarette carton packaging, and in particular relates to a transparent printing packaging film for replacing paper carton labels of cigarettes which avoids film adhesion and a preparation method thereof. Background technique [0002] At present, cigarette small boxes and cartons are packaged with color-printed paper materials (paper cigarette labels), and outside the paper packaging, cigarettes are packaged with heat-sealable BOPP film to achieve moisture-proof and The purpose of improving the effect of cigarette packaging. Paper cigarette labels need to be bonded with glue during the packaging process. The use of glue will pollute the environment, and the extensive use of paper materials will also have an impact on resources and the environment. The existing technology that can replace the paper box cigarette label is realized by applying acrylic ...

AI Technical Summary

Problems solved by technology

Paper cigarette labels need to be bonded with glue during the packaging process. The use of glue will pollute the environment, and the extensive use of paper materials will also have an impact on resources and the environment.

The existing technology that can replace the paper carton label is realized by applying acrylic acid coating on the BOPP film, and the production cost of using this technology is relatively high

At the same time, the initial heat-sealing temperature of the existing heat-sealable BOPP film for cigarettes is generally between 110°C and 120°C. If this film is used to replace the paper carton label of cigarettes, it will It will be bonded with the BOPP film of the small box packaging, affecting the packaging effect, and consumers will tear the BOPP film of the small box packaging together when unpacking, affecting the use
