Flexography vacuum aluminizing product with anti-counterfeit mark, vacuum aluminizing system and production process

Abstract

The invention relates to an aluminizing product with an anti-counterfeit mark, a vacuum aluminizing system and a vacuum aluminizing process, which belong to the field of packing materials. The aluminizing product comprises a substrate and a coating layer, an aluminizing layer and a protecting layer which are sequentially covered on the substrate. The aluminizing product is characterized in that the aluminizing layer with an anti-counterfeit mark pattern is arranged between the coating layer and the protecting layer. The aluminizing system is characterized in that an oil tank is arranged insidethe aluminizing system; a transfer roll is arranged above the oil tank; a scrapper is arranged in front part of the contacted and matched part of the transfer roll and a printing roll; the outside ofthe printing roll is close to an aluminizing process roll; and the substrate is arranged on the contacted and matched periphery of the aluminizing process roll and the printing roll. The process comprises the following steps: 1. substrate selection; 2. coating layer; 3. corona discharge; 4. printing; 5. aluminizing; and 6. protecting layer coating. The aluminizing layer with the anti-counterfeitmark printing patterns is formed by closely combining the fundamental principle and method of the flexography with the vacuum aluminizing process. The formed anti-counterfeit mark has the characteristics of distinctive nuance, clear darkness and brightness and life-like image, as well as heavy metal texture and good anti-counterfeiting effect, thereby being difficult to simulate.

Description

technical field [0001] The invention relates to a flexographic printing vacuum aluminized product with an anti-counterfeit mark, a vacuum aluminized system and a production process thereof, and belongs to the technical field of packaging materials and decorative materials. Background technique [0002] At present, the known vacuum aluminum-coated paper with anti-counterfeit marks is mostly produced by the process with holographic anti-counterfeit patterns, and its basic process is divided into direct plating method and transfer method. [0003] 1) Direct aluminum plating method: [0004] 1. Molding on OPP film to form OPP film with holographic anti-counterfeiting mark; [0005] 2. Composite the OPP film with holographic anti-counterfeiting mark and the paper substrate; [0006] 3. Peel off the OPP film with the holographic anti-counterfeiting mark from the paper substrate, and the holographic anti-counterfeiting mark is transferred to the paper substrate; [0007] 4. Alum...
