Preparation method of aluminum-free transparent laser environmental-protection inner liner for cigarette

Abstract

The invention discloses a manufacturing method of an aluminum-free transparent laser environmental-protection inner liner for cigarette. The aluminum-free transparent laser environmental-protection inner liner for cigarette comprises paper, a PET film and a waterborne transfer adhesive. According to the manufacturing method, the PET film is molded through a molding press to form a laser pattern with various patterns, and then is combined with paper by the use of the waterborne transfer adhesive; after the PET film is peeled, the laser pattern is transferred to the paper; a layer of transparent medium is plated on the PET film-peeled paper with the laser pattern by the use of a vacuum aluminum plating machine; the transparent medium-plated paper with the laser pattern undergoes water supplement treatment; and a cigarette logo pattern is printed by the use of a photogravure press. By reasonable proportioning and a new technology, the prominent problem that embossing of paper is fuzzy, is easy to bounce back and is not resistant to folding is solved. In comparison with the prior art, the method provided by the invention is environmentally friendly and can be used to maintain original physical properties of paper. By the method, aluminum-free transparent laser environmental-protection inner liner for cigarette has advantages of good flexibility and molding degree, no bouncing-back, folding resistance, clear and accurate printed typeface and the like.

Description

technical field [0001] The invention relates to an inner lining paper, in particular to a method for preparing the inner lining paper for cigarettes. Background technique [0002] At present, the lining paper for cigarettes generally adopts direct aluminized laser lining paper or transfer aluminized layer laser lining paper. Compared with the original composite aluminum foil lining paper, this technology has greatly improved environmental protection, but it still needs to be used To high-purity metal aluminum wire, it is not 100% environmentally friendly. Moreover, during the packaging process of the inner liner paper on the cigarette packaging machine, some of the inner liner paper has the phenomenon of aluminum powder falling off, which affects both the packaging effect and the packaging efficiency. At the same time, during the process of aluminum plating or transfer drying of the lining paper, the paper loses too much water, which causes the paper to become brittle, and ...
