Cigarette aluminum-foil paper with anti-counterfeiting label

Abstract

The invention provides cigarette aluminum-foil paper with an anti-counterfeiting label. The cigarette aluminum-foil paper comprises liner paper and an aluminum foil layer. An anti-counterfeiting laser film is arranged on the surface of the aluminum foil layer. The manufacturing process comprises the steps that the laser film is manufactured, an aluminum foil body coated with glue is heated and baked, the laser film and the aluminum foil are composited, a BOPP film is stripped from a cured semi-finished product, a BOPP base film on a cooled composited film is removed, a complexing agent for connecting the liner paper and the aluminum foil layer is prepared, and finally the liner paper and the aluminum foil layer are composited. The BOPP base film has the good temperature resistance and ageing resistance, materials are soft, no transparent de-bonding layer needs to coat the materials, and the technological process is simple; the anti-counterfeiting film is transferred onto aluminum foil, laser patterns will not disappear and are not likely to be damaged, and the while film is good in high temperature resistance and will not crack. The complexing agent between the liner paper and the aluminum foil layer is not likely to volatilize to generate hazardous substances, the temperature is high, and adhesive force can be provided for the liner paper and the aluminum foil layer for a long time.

Description

technical field [0001] The invention relates to the technical field of cigarette packaging, in particular to a cigarette aluminum foil paper with an anti-counterfeiting mark. Background technique [0002] Laser anti-counterfeiting is to use a laser light source to record the light wave amplitude information and corresponding information at the same time in a very short period of time. With thousands of interference barcodes per millimeter, using the principle of light interference, each particle that constitutes the image is reflected, that is, Laser hologram. After making a plate, it is impossible to produce exactly the same plate with the same production method, so as to achieve the purpose of anti-counterfeiting. [0003] The current laser anti-counterfeiting transfer film is made of PET transfer film. The PET transfer film is first coated with a transparent release layer on the PET base film, and then coated with a transparent molded layer on the transparent release la...

Problems solved by technology

Because the can industry needs to stretch to make can lids, the laser pattern on the stamping place will easily disappear or be destroyed after punching; They all use thermosetting inks, and the printing must be baked in an oven at 190°C-220°C for at least 18 minutes per color, and the transparent release layer and molded layer cannot withstand such a long-term high-temperature baking at all. Cracks will occur under the environment, which cannot meet the needs of users at all. At present, there is no technical solution to solve this problem.
