Half-metalized holographic copper-plated film and preparing method thereof

Abstract

The invention discloses a half-metalized holographic copper-plated film and a preparing method thereof. The copper plated film comprises a transparent base layer, a transparent release layer, a transparent holographic layer and a hot melting glue layer which are sequentially glued together from top to bottom, a copper-plated layer corresponding to the holographic layer is arranged under the holographic layer, and a protecting layer consistent with the copper-plated layer is arranged under the copper-plated layer and glued with the hot melting glue layer. The preparing method thereof includes the steps of: coating the release layer on the base layer, coating the holographic layer on the release layer, plating copper on the holographic layer in a vacuum manner, pressing, printing the protecting layer on the copper-plated layer, and cleaning copper by chemical etching with 25%-35% mass of ferric chloride complex solution at the temperature of 55-60 DEG C. The position of the copper-plated layer corresponds to holographic patterns, and the purpose for mutual reflection is achieved.

Description

technical field [0001] The invention belongs to the field of anti-counterfeiting marks, and in particular relates to a positioned localized copper plating, a partially transparent holographic film, or a partially transparent hot stamping anti-counterfeiting mark, and also relates to a preparation method of the copper-plated film. Background technique [0002] After nearly 30 years of development, laser holographic technology has been widely used in various industries, especially the holographic aluminum coating and holographic dielectric coating, which have effectively improved the grade of products due to their dazzling colors and high reflectivity. It has been widely praised, but with the development of the times, the anti-counterfeiting performance of the traditional packaging film has been reduced due to the expansion of the market, and it needs to be combined with other technologies to meet the needs of the market. At the same time, the holographic film of the aluminized...

Problems solved by technology

[0002] After nearly 30 years of development, laser holographic technology has been widely used in various industries, especially the holographic aluminum coating and holographic dielectric coating, which have effectively improved the grade of products due to their dazzling colors and high reflectivity. It has been widely praised, but with the development of the times, the anti-counterfeiting performance of the traditional packaging film has been reduced due to the expansion of the market, and it needs to be combined with other technologies to meet the needs of the market. At the same time, the holographic film of the aluminized medium The grade of the film can not meet the customer's requirements

[0003] After years of technical accumulation, laser holographic marking has been widely used in various industries such as tobacco, daily chemicals, and securities. However, with the development of the times, the anti-counterfeiting performance of the traditional holographic anti-counterfeiting label has been reduced due to the expansion of the market. It needs to be combined with other technologies to meet the needs of the market. At the same time, the traditional holographic anti-counterfeiting The laser holographic anti-counterfeiting mark is mainly made of gold anodized aluminum, which has defects in texture and brightness, and cannot meet the requirements of high-end products

[0004] On the other hand, the current process of aluminized film includes the following steps in sequence: coating a release layer on the substrate layer, coating a holographic layer on the release layer, plating aluminum on the holographic layer, embossing, coating the aluminum layer Printing protective layer, aluminum washing, aluminum washing generally adopts alkali washing, which is not only costly, but also the solution after washing aluminum is alkaline, which is not easy to handle and easily causes secondary pollution
