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 inside the 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 of the 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
The present invention relates to the vacuum aluminum-coated product of a kind of flexographic printing, vacuum aluminum-coated system and production technology thereof, belong to packaging material and decorative materials technology with anti-counterfeiting mark.
Background technology
At present, the vacuum aluminium-plated paper of known band anti-counterfeiting mark adopts the explained hereafter of band holographic false proof pattern more, and its typical process flow is divided into two kinds of straight plating method and transfer methods.
One) direct Alplate method:
