Glass mirror surface bright gold card paper structure and production method thereof

Abstract

The invention discloses a glass mirror surface bright gold card paper structure and a production method thereof. The glass mirror surface bright gold card paper structure comprises a back coating, a white card bottom layer, a metal imitation glass layer, a varnish color layer and a printing finishing layer from bottom to top, the metal imitation glass layer is made of a mixture of water-based high-brightness silver and imitation glass card glue; the method comprises the following steps: adding a water-based high-brightness silver coating into glass card imitating glue, coating, carrying out film pressing by using a PET base film, curing, stripping the PET base film, and carrying out coloring treatment (or directly slitting into high-brightness silver cards) on glass card imitating backingpaper according to the required color, so as to realize the gold and silver card paper with the glass card imitating effect. According to the invention, the water-based high-brightness silver coatingis added into the glass card imitation glue to form the metal glass imitation layer, and the metal glass imitation layer is adopted, so that the glass mirror surface bright gold card paper is easier to prepare and lower in cost, the use amount of a base film is greatly reduced, and the pollution is reduced.

Description

technical field [0001] The invention belongs to the technical field of packaging box printing, and relates to a glass-mirror bright gold cardboard structure and a production method thereof. Background technique [0002] Coating white cardboard with imitation glass card glue paint, and then performing film pressing with PET base film, can obtain a kind of imitation glass cardboard with bright and smooth surface. This process has been realized and promoted in the industry. [0003] In addition, gold and silver card paper is a common packaging and printing material, which is widely used, and its surface metal effect is mainly realized by the aluminum layer. The main processing techniques include PET aluminum-coating composite transfer processing technology and PET aluminum-spraying composite transfer processing technology. Both processes need to use PET film or OPP film as the base film of the aluminum layer. According to the latest base film recycling technology on the market...

AI Technical Summary

Problems solved by technology

Both processes need to use PET film or OPP film as the base film of the aluminum layer. According to the latest base film recycling technology on the market, only 3-5 times of recycling can be realized. The consumption of raw material resources is very large, and the base film cannot be naturally degraded. , causing great environmental pollution
