Production process of aluminized laser paper

Abstract

The invention relates to the technical field of packaging bag paper production, in particular to a production process of aluminized laser paper. The production process comprises the following steps: 1) coating a release agent on a substrate to form a release layer; 2) drying the substrate coated with a release material; 3) imprinting a dried film so that the surface of the substrate can have a laser pattern; 4) conducting vacuum aluminum plating on the substrate, and then conducting protected layer coating on a specified position; 5) immersing the substrate coated with the protected layer in an alkaline liquid pool for aluminum washing and drying again; 6) conducting spot-coating on the surface of the substrate, then compounding the substrate and base paper through a compound device and then drying again; 7) curing composite paper, peeling off the substrate, and transferring the laser pattern to the surface of the base paper. After the release agent is used on the substrate, the durability, compression resistance, solvent resistance, and low temperature resistance are improved, and at the same time, and an alkaline solution can be effectively prevented from excessively eroding thesubstrate when aluminum is washed.

Description

technical field [0001] The invention relates to the technical field of packaging bag paper production, in particular to a production process of aluminized laser paper. Background technique [0002] Laser film generally adopts computer dot matrix lithography technology, 3D true color holographic technology, multiple and dynamic imaging technology, etc. The holographic image with rainbow dynamics and three-dimensional effect is transferred to PET, BOPP, PVC or coated substrates by molding, and then the surface of the product packaging can be obtained with a certain laser effect by lamination, hot stamping, transfer, etc. [0003] However, in the existing packaging printing technology, since the base material needs to be peeled off during the transfer process of the laser film, some aluminum-plated products need to wash the base material before peeling off, and the release coating lacks durability and resistance. In the case of poor compressibility and solvent resistance, the ...

Problems solved by technology

[0003] However, in the existing packaging printing technology, since the base material needs to be peeled off during the transfer process of the laser film, some aluminized products also need to wash the base material before peeling off, and the release coating lacks durability and resistance. In the case of poor compressibility and solvent resistance, the transfer aluminum plating pattern of the packaging paper is prone to problems such as unclear edges and broken lines, which will affect the product quality
