Vacuum-coated aluminum paper having false-proof hologram pattern and method for making same

Abstract

The present invention is vacuum aluminum plating paper with anti-fake holographic pattern and its making process, and belongs to the field of aluminum plating paper making technology. The vacuum aluminum plating paper comprises one paper base and one primary coating, one aluminum coating, one bright coating and one characterized anti-fake holographic pattern layer successively on the paper base. Its making process includes the following steps: sorting paper base, painting the primary coating, vacuum plating aluminum to form the aluminum coating, painting the bright coating, loading the anti-fake holographic pattern layer, rehumidifying, embossing, cutting, printing, etc. The vacuum aluminum plating paper with anti-fake holographic pattern has bright pattern and optional laser anti-fake effect and relatively simple production process.

Description

1. Technical field [0001] The invention relates to vacuum aluminized paper and a preparation method thereof, belonging to the technical field of aluminized paper. 2. Background technology [0002] Vacuum aluminum-coated paper (or aluminum-sprayed paper, aluminum-coated paper, vapor-deposited paper) is a new type of green packaging material used in the packaging industry. Because of its good metal texture, relatively low material cost, and its degradable and recyclable environmental protection properties, it is more and more popular among people. [0003] Vacuum aluminum-coated paper can be divided into two types according to the production process: direct aluminum plating (paper surface aluminum plating) and transfer aluminum plating method (film surface aluminum plating). The direct aluminizing method is to place the paper substrate directly in a vacuum aluminum coating machine for aluminizing. After coating the surface of the paper substrate with an aluminum coating, vacu...

Problems solved by technology

[0007] The purpose of the present invention is to solve the defect that the aluminized paper produced by the vacuum direct aluminizing method in the above-mentioned prior art has no anti-counterfeiting pattern and cannot meet the requirements of high-grade anti-counterfeiting packaging, and further solve the aluminized paper produced by the vacuum direct aluminizing method in the prior art There are defects such as low reflectivity of metallic luster on the surface, rough and porous paper surface that cannot be effectively covered, poor paper surface flatness, low brightness after aluminizing, and inability to meet the requirements of high-end anti-counterfeiting packaging. A tape is prepared by vacuum direct aluminizing method. Vacuum aluminum-coated paper with high-definition anti-counterfeit holographic pattern and its preparation method, as well as rough and porous paper surface that can be effectively covered up, improved paper surface flatness and formability, and improved metallic luster and mirror reflectivity on the surface, which can adapt to high-end anti-counterfeit packaging Required vacuum aluminized paper with anti-counterfeit holographic pattern and preparation method thereof
