Problems solved by technology

Moreover, the existing single-layer printing packaging film has poor barrier properties, and after full-page printing, the heat-sealing performance of the printing surface is greatly reduced; while the aluminum-coated surface of the existing single-layer aluminum-coated packaging film does not have heat-sealing properties, and is not durable Scratches, so the functionality is not strong during use, and the application is greatly limited

Abstract

The invention discloses an aluminized and printed composite packaging film for tobaccos and a preparation method of the aluminized and printed composite packaging film. The composite packaging film comprises a printed packaging film and an aluminized packaging film which are compounded by using an adhesive, and the composite packaging film can be obtained by compounding a printed layer of the printed packaging film with an aluminized layer of the aluminized packaging film. The invention creatively puts forwards the combination of a printed surface of the printed packaging film and an aluminized surface of the aluminized packaging film, so that not only is the problem that the heat sealing performance of the fully-printed surface of an existing printed packaging film is reduced solved, butalso the aluminized and printed composite packaging film has extremely high barrier performance; due to the combination of the printed surface of the printed packaging film and the aluminized surfaceof the aluminized packaging film, not only can double surfaces be subjected to heat sealing, but also a printing function is realized, and the aluminized layer is prevented from being scratched; and the aluminized and printed composite packaging film for tobaccos realizes low-temperature heat sealing on the basis of existing functions, effectively reduces the energy consumption and is environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of novel polymer packaging materials, and in particular relates to an aluminized and printed composite packaging film for cigarettes and a preparation method thereof. Background technique [0002] Traditional cigarette packaging films use transparent biaxially oriented polypropylene films. According to the current packaging form, only one layer of transparent packaging film is added outside the paper cigarette label to play a certain sealing effect. Moreover, the existing single-layer printing packaging film has poor barrier properties, and after full-page printing, the heat-sealing performance of the printing surface is greatly reduced; while the aluminum-coated surface of the existing single-layer aluminum-coated packaging film does not have heat-sealing properties, and is not durable Scratches, so the functionality is not strong during use, and the application is greatly limited. [0003] In view of the...
