Aluminum-sprayed paper with local holographic variable visual angle and lens stereoscope and manufacturing method thereof

Abstract

The invention provides an aluminum-sprayed paper with a local holographic variable visual angle and a lens stereoscope. The aluminum-sprayed paper is characterized by comprising a base paper layer, an adhesive layer, a metal coating, a holographic variable visual angle and lens stereoscope laser information layer and a coating transferring layer which are arranged in sequence. According to the aluminum-sprayed paper with the local holographic variable visual angle and the lens stereoscope in the invention, the lens stereoscope employs a local-focus arc-photoetching manner, so the problems of low success rate and high cost of conventional cat-eye lenses processed with mechanical lathes are overcome.

Description

technical field [0001] The invention relates to a local holographic variable viewing angle and three-dimensional lens aluminum-sprayed paper, and also relates to a manufacturing method of the local holographic variable viewing angle and three-dimensional lens aluminum-sprayed paper, which belongs to the technical field of packaging materials. Background technique [0002] As an environmentally friendly material, paper is widely used in various packaging products. However, with the diversification of products and the continuous improvement of people's aesthetic requirements, simple white cardboard packaging can no longer meet the needs of customers, while plastic packaging, Metal packaging does not conform to the development trend of environmentally friendly packaging, so a new type of packaging material - holographic packaging material has emerged in recent years. Holographic packaging material is a kind of packaging material made by making laser holographic technology into ...

Problems solved by technology

[0005] First, because the cat's eye lens is formed by machining on a stainless steel stone lathe, the processing accuracy is high, and the cat's eye transparency is determined by the radian of the processing curve, and the processing success rate is low and low

[0006] Second, since the cat's eye lens is formed by deep-grain mechanical processing, the combination with the laser holographic pattern needs to be combined with the UV plate method, and the positioning plate accuracy will be deviated, which will affect the positioning accuracy of the final packaging material and bring difficulties to printing overprinting.

[0007] Third, due to the deep texture of the cat's eye lens formed by mechanical processing, reaching about 10 μm, the transfer cannot be achieved by ordinary coating methods, only by UV coating methods. The production speed of ordinary coating can reach 110 m / min, while UV coating Only 30m / min, low production efficiency

[0008] Fourth, ordinary coating transfer coating, the coating amount is only 1 ~ 1.4g, while the cat's eye lens has a deep texture, reaching about 7 ~ 8μm, it can only be applied by UV coating, the coating amount reaches 10g, and the cost is very high

[0009] Fifth, the cat's eye and laser holographic film that is molded by UV coating cannot be transferred because the texture is too deep, so the film and paper can only be pasted together. Since there is a layer of film attached to the surface, it cannot be effectively degraded, so it does not meet the packaging requirements. The development trend of material environmental protection
