Problems solved by technology

[0003]In the prior art, the laser printing film includes a carrier layer, a laser imaging layer and an aluminum layer in sequence. When the laser printing film is used in the packaging industry, it usually needs to be combined with UV ink Combination, however, the combination of laser printing film and UV ink in the prior art is not good enough, and the ink often falls off during the use of the product, which seriously affects the market competitiveness of the product

Abstract

The invention relates to the technical field of laser printing films, and particularly relates to a laser printing film and a fabrication technology thereof. The laser printing film sequentially comprises a polyethylene terephthalate (PET) base film, a coating layer, a laser layer and an aluminium layer, and also comprises an acrylic resin layer which is coated on the other surface of the PET base film. The fabrication technology of the laser printing film comprises the following steps: 1, dissolving nitrocotton into ethyl acetate to obtain nitrocotton liquid; 2, coating one surface of the PET base film with the nitrocotton liquid, and baking to obtain the coating layer; 3, heating the coating layer until the coating layer becomes soft, and then coining laser grains on the coating layer, so as to obtain the laser layer; 4, plating the aluminium layer on the surface of the laser layer by using a vacuum aluminum plating machine; and 5, coating the acrylic resin on the other surface of the PET base film, and baking to obtain the acrylic resin layer, so as to obtain the laser printing film. The laser printing film is good in combination degree with UV (Ultraviolet) ink, so that the paint of the laser printing film does not peel off in the use procedure.

Description

technical field [0001] The invention relates to the technical field of laser printing films, in particular to a laser printing film and a manufacturing process thereof. Background technique [0002] Laser printing film is widely used in the packaging industry. Compared with other products in the packaging industry, laser printing film not only has a novel and bright appearance, but also has high-tech anti-counterfeiting functions. It is known as the most advanced in the world's packaging and printing industry. technical product. The application field of laser printing film has been very extensive, and it is mostly used in high-grade packaging boxes, high-grade cigarette packaging boxes, lamination, pharmaceutical and cosmetic packaging and other occasions. [0003] In the prior art, the laser printing film sequentially includes a carrier layer, a laser imaging layer and an aluminum layer. When the laser printing film is used in the packaging industry, it usually needs to be...
