Laser transfer paper, and production technology thereof

Abstract

The invention discloses laser transfer paper and production technology thereof. The laser transfer paper comprises a laser transfer coating layer, laser patterns printed onto the laser transfer coating layer, an aluminizing layer used for coating the laser transfer coating layer through plating, a protective rubber layer which is used for coating the aluminizing layer and protecting a part of the aluminizing layer, and a zinc sulfide dielectric layer which is used for coating the protective rubber layer through plating; and the zinc sulfide dielectric layer is bonded with a paper base through a transfer glue. According to the laser transfer paper, the laser patterns with hollowing out effect are formed, so that the appearance effect of the laser transfer paper as packing paper is improved; the bonding capacity of a peeling coating layer with a tackifying bottom coating layer is increased, so that the stability of laser transfer film in subsequent processing process is ensured; at the same time, the surface tension of the coating layer after curing is reduced, the coating layer peeling effect is improved, and light transmission and white exposure caused by peeling of a part of the laser transfer coating layer are prevented; in laser transfer coating layer preparation process, resin system light transmission effect is improved, so that the reflective effect of the laser patterns is improved.

Description

technical field [0001] The invention belongs to the technical field of packaging materials, and in particular relates to a laser transfer paper and a production process thereof. Background technique [0002] Laser transfer paper is an emerging packaging material, mainly used in the packaging of tobacco, alcohol, cosmetics and other products. Laser transfer paper transfers the aluminized coating with a laser effect to the paper base to form an aluminized aluminized coating with a metallic luster. The laser effect of laser transfer paper makes laser transfer paper have a completely different appearance style from traditional packaging paper, and its colorful and peculiar effects also make it more and more accepted and applied in the field of packaging materials. [0003] In the prior art, laser transfer paper mainly includes transparent laser film and metal laser film. Both laser films have good appearance effects, but the laser effect is single and lacks changes. At the same ...

Problems solved by technology

[0003] In the prior art, laser transfer paper mainly includes transparent laser film and metal laser film, both of which have good appearance effects, but the laser effect is single and lacks changes. At the same time, in the prior art, the production of laser transfer paper The laser transfer film is prepared with PET film as the base film, and then the laser transfer film is combined with the paper base, and the laser graphic information on the laser transfer film is transferred to the laser transfer paper, so that the brilliance of the laser pattern can be better displayed. However, when the PET film is peeled off, the PET film and the adhesive layer printed with the laser pattern cannot be fully separated, resulting in uneven effect of the laser pattern on the obtained laser transfer paper, and even whiteness, light leakage, and scrapping. Improve the quality and production efficiency of laser transfer paper, improve the cost of enterprise production, in order to solve this problem, the present invention provides the following technical solutions
