Production process for environment friendly laser card paper

Abstract

The invention relates to a production process for environment friendly laser card paper. The production process comprises the following steps: (1) uniformly coating one layer of laser imaging coating on the card paper by using a coating machine, and drying and solidifying the laser imaging coating to form transparent surface coating on the card paper; and (2) impressing the surface of the transparent surface coating by using a laser mold pressing plate with laser graphic information, and transferring the laser graphic information on the laser mold pressing plate on the transparent surface coating to obtain the laser card paper. Compared with the traditional production process for the laser card paper, the production process for the environment friendly laser card paper has the following beneficial effects that (1) the process is environment friendly; (2) the technological process is optimized, the process steps are simplified and equipment configuration and material consumption are reduced, so cost is saved, and production efficiency is improved; (3) the production is easy to control, so that the laser graphic information is easy to transfer, the anti-fake effect is obvious, quality problem caused by deformation of the base material is avoided, and the product quality is stable; and (4) the laser image text on the laser card paper is clear.

Description

technical field

[0001] The invention relates to the technical field of cardboard processing, in particular to an environment-friendly production process of laser cardboard. Background technique

[0002] Laser cardboard is a kind of packaging material with laser graphic information. It has anti-counterfeiting effect and strong aesthetic feeling. It is widely used in the outer packaging of tobacco, wine, cosmetics, medicine and other products.

[0003] At present, the production process of most laser cardboards is relatively complicated, and must be coated (coating the molded layer on the plastic film), molded (the laser graphics are molded on the molded layer), vacuum aluminum plating (vacuum plated on the molded layer) Aluminum, forming the aluminum layer), transfer (bonding the aluminum layer and the cardboard together), peeling (peeling off the plastic film) and other processes.

[0004] There is also a production process of laser cardboard. By improving the plastic film,...
