Embodiment Construction

[0016] Produce a type of lining paper for "Zhonghua" brand soft pack cigarettes from Shanghai Cigarette Factory, the specification is 74g114mm, and the production quantity is 200 meters.

[0017] Carry out laser holographic laser molding on 0.2mm BOPP film, vacuum aluminum plating on the molding surface, and apply a coating to the aluminum layer on the roller coating equipment. The anilox roller used in the roller coating equipment is 150 mesh 65um, and the coating The paint formula weight ratio is as follows: 8% butyl methacrylate, 8% methyl methacrylate, 1% acrylic acid, 3% methyl acetate, 2% sodium lauryl sulfate, 1% super Composition of ammonium sulfate, 52% water and 25% ethanol.

[0018] After storage and curing at room temperature for 24 hours, a BOPP laser film is obtained.

[0019] Coat the adhesive on the coating layer of BOPP laser film or the base paper, roll the BOPP laser film and the base paper, and put it at room temperature for 24 hours to cure, and then peel...

Abstract

The invention aims at providing a method for producing direct transfer laser hologram lining paper, which can be used for obtaining fine and clear laser patterns and comprises the following steps of: performing laser hologram mold compression and vacuum aluminizing on a BOPP (Biaxially-Oriented Polypropylene) film, coating a coating layer on the aluminized layer, stripping out the BOPP film after the coating layer is compounded with original paper through rolling, and coating gloss oil. Through the method, the technical process is simplified, the pure aluminum foil layer in the common laser hologram lining paper is omitted, and the adhesive is compounded by using a dry method. Compared with the compounding of common laser aluminum foil, the use amount of metal aluminum and the adhesive is omitted, and the energy consumption and the production cost are reduced. By using water-based back paint and surface paint, the harm of auxiliaries remained in the raw paint to the environment and human bodies is eliminated, the stripped BOPP film can be reused, and another mold compression of laser hologram patterns is not required.

Description

technical field [0001] The invention relates to a manufacturing method of packaging materials, in particular to a manufacturing method of laser holographic inner lining paper used in cigarette packaging. Background technique [0002] At present, 90% of the middle and high-end products of cigarettes use ordinary laser holographic laser aluminum foil paper. The entire surface of the laser aluminum foil paper has holographic anti-counterfeiting characters or patterns. Difficulty, with good anti-counterfeiting function, so the production cost of this product is relatively high. In this context, reducing production costs as much as possible is the common goal of all manufacturers: the thickness of the aluminum foil of ordinary laser holographic aluminum foil paper is generally 6-7 microns, while the thickness of the aluminum layer of direct transfer laser holographic laser lining paper is only The thickness of the aluminum foil is 300-400 angstroms, and the thickness of the alum...
