[0044] 10000 products.

[0045] (1) Coating release imaging layer: choose double-sided corona-free PET with a thickness of 16 μm as the base material, and use a coating machine to coat the BH-1001C coating produced by Shanghai Weikai Chemical Co., Ltd. on it, and the coating viscosity is 19s , dry coating amount 1.1g / m 2 . The coating temperature was 90°C. The vehicle speed is 70 m / min. The 90-degree peel strength (flexibility to flexibility) between the release layer and the PET layer was 0.003 N / mm.

[0046] (2) Design: Design gravure and holographic plates according to customer needs and product specifications and models. In order to improve its anti-counterfeiting strength, during the design process, plate-making anti-counterfeiting means are properly embedded in it according to the design pattern, so that the authenticity can be identified later. At the same time set the positioning cursor. Ready for post-printing and transfer work. Holographic version production: u...

Abstract

The invention belongs to the technical field of packaging materials and particularly relates to a multiple metal color anti-counterfeiting aluminum foil sealing gasket and a preparation method thereof. The multiple metal color anti-counterfeiting aluminum foil sealing gasket is formed by sequentially connecting a mold imaging layer, a color printing layer, a holographic information layer, an aluminizing layer, a medium layer, an induction layer, an EVA adhesive layer and a sealing layer from outside to inside. The preparation method comprises the steps of mold imaging layer coating, designing, gravure mold pressing, aluminizing, composite transferring and sealing layer compositing, so that the sealing gasket is obtained. A gravure and mold pressing integrated method is adopted so that a multiple metal color holographic graphic anti-counterfeiting technology is realized on a same layer, and the visual impact and the anti-counterfeiting intensity are enhanced; a consumer can check and distinguish the sealing gasket easily, all anti-counterfeiting characteristics can be implemented and checked, a site inspection function can be realized, and simultaneously the unfulfillable non-transferability of an anti-counterfeiting mark is realized; an environment-friendly material is composited for manufacturing the anti-counterfeiting aluminum foil sealing gasket, so that the environment protection function is improved.

Description

technical field [0001] The invention belongs to the technical field of packaging materials, and in particular relates to a multi-metal color anti-counterfeiting aluminum foil sealing gasket and a preparation method thereof. Background technique [0002] In the filling or bottle packaging of food or medicine, electromagnetic induction aluminum foil gaskets are usually used to seal the seal to block air and moisture and achieve the purpose of extending the shelf life of food or medicine. Drugs are directly related to human health, so the anti-counterfeiting of food and drugs has become a top priority. [0003] The current multi-color anodized aluminum is composed of layers, that is, the aluminized film of one color is compounded on the aluminized film of another color. Low, material waste is serious, and production cost is high. Contents of the invention [0004] The purpose of the present invention is to provide a multi-metal color anti-counterfeiting aluminum foil sealin...
