Abstract

The invention discloses a production method of anti-counterfeiting transfer paper with a small fisheye effect. The production method of the anti-counterfeiting transfer paper with the small fisheye effect comprises the steps: (1) producing transfer paint with a modified acrylate polymer as base material resin; (2) coating a PET film with the transfer paint to obtain a transfer layer; (3) conducting mould pressing on the transfer layer on a mould press to obtain a laser information layer; (4) conducting vacuum aluminizing on the transfer layer to obtain an aluminized layer; (5) coating the aluminized layer with water-based glue, and conducting drying after the aluminized layer coated with the water-based glue and body paper are compounded; (6) coating the rear surface of compounded paper with gum, and conducting drying; and (7) peeling off the PET base film on a surface of the compounded paper to obtain the anti-counterfeiting transfer paper with the small fisheye effect. According to the anti-counterfeiting transfer paper, produced through the production method, with the small fisheye effect, under ultraviolet light, small fisheye particles dispersed at the center of the laser information layer can be seen, other layers with anti-counterfeiting functions do not need to be added, thus the risk that a simple laser film is liable to be copied can be avoided, the paint and the laser information layer are combined to enhance the anti-counterfeiting effect, the printing adaptability is not affected, and the anti-counterfeiting transfer paper with the small fisheye effect is anti-counterfeiting and easy to check.

Description

technical field [0001] The invention relates to the field of packaging printing, in particular to an anti-counterfeiting transfer paper with small crystal point effect and a preparation method thereof. Background technique [0002] Transfer paper is one of the most widely used tobacco packaging materials. However, with the development of the economy, the contradiction between counterfeiting and anti-counterfeiting has become more and more acute. In order to protect the corporate brand, the market and the legitimate rights and interests of consumers, it is imperative to take certain anti-counterfeiting measures. The transfer paper with anti-counterfeiting function is widely favored by merchants. It not only has anti-counterfeiting properties, but also has the effect of improving its own brand image. The traditional anti-counterfeiting method of transfer paper is to transfer the laser mold with printed pattern to the packaging paper through bonding and compounding processes, ...
