Embodiment 1

[0017] Example 1: The degradable cigarette transparent packaging material is composed of 95% regenerated cellulose film and 5% polyvinylidene chloride by weight. The specific preparation process is as follows: use a regenerated cellulose film with a thickness of 27 microns, adopt a roll-transfer coating method, and coat polyvinylidene chloride emulsion with a solid content of 50% on both sides to obtain a coating with a thickness of 28 microns. Regenerated cellulose film, in which the coating thickness is 0.5 microns, and after printing the cigarette label pattern of a specific cigarette brand on one side of the coating layer, it is used in the production of cigarette packaging without any printing treatment on the cigarette label paper, so that the cigarette transparent packaging material The printed pattern is exposed on the outer surface, and the cigarette package is beautiful and decent. After consumers buy cigarettes, they can tear off the outermost layer of cigarette tr...

Embodiment 2

[0018] Example 2: The degradable cigarette transparent packaging material is composed of 85% regenerated cellulose film and 15% polyvinylidene chloride by weight. The specific preparation process is as follows: using a 10-micron regenerated cellulose film, using a spraying method, coating polyvinylidene chloride emulsion with a solid content of 70% on both sides, and preparing a coated regenerated cellulose film with a thickness of 16 microns. The coating thickness is 3 microns. The printed pattern on the transparent packaging material of the cigarette is located on its inner surface; consumers tear off the outermost transparent packaging material of the cigarette, leaving the cigarette package with a simple design.

Embodiment 3

[0019] Example 3: The degradable cigarette transparent packaging material consists of 90% regenerated cellulose film and 10% polyvinylidene chloride by weight. The specific preparation process is as follows: a regenerated cellulose film with a thickness of 33 microns is prepared by coating a polyvinylidene chloride emulsion with a solid content of 60% on both sides by using a regenerated cellulose film of 27 microns. The thickness is 3 microns.

Abstract

The invention relates to the field of cigarette packaging materials, in particular to a degradable transparent packaging material for cigarettes, which is characterized by being prepared by coating polyvinylidene chloride emulsion with solid content of 50-70% on a regenerated cellulose film with the thickness of 10-27 microns, wherein in the packaging material, polyvinylidene chloride accounts for 5-15 parts and regenerated cellulose accounts for 85-95 parts in parts by weight. The degradable transparent packaging material for the cigarettes, namely a cigarette packaging film, is mature in process, is degradable, and can ease great psychological pressure of smokers caused by visualized smoking-cessation warning indeed.

Description

technical field [0001] The invention relates to the field of cigarette packaging materials, in particular to a degradable transparent packaging material for cigarettes. Background technique [0002] In order to prevent the cigarettes from getting damp and losing moisture and aroma, and to beautify the appearance of the product, a layer of packaging film is wrapped outside the small cigarette box and carton. This film is called cigarette transparent packaging material, also called cigarette film. The development of cigarette film has mainly undergone three generations of changes. The first generation is cellophane, or cellophane. The defect of cellophane is poor heat sealing performance; the second generation is heat-sealing biaxially oriented polypropylene film, namely BOPP film, polypropylene film The film has stable dimensions, low moisture and oxygen permeability, high strength, and good printing effect, so its overall performance is better than that of cellophane; the th...
