A kind of laser anti-counterfeiting material and its processing technology for medicine packaging

Abstract

The invention discloses a laser anti-counterfeiting material used for medicine packaging. The laser anti-counterfeiting material comprises an outer protective layer, a laser anti-counterfeiting layer, an aluminum foil layer, a lining paper layer, a paper board layer and a shading material layer. The laser anti-counterfeiting layer is attached to the glaze surface of the aluminum foil layer; the outer protective layer is a transparent layer and is attached to the surface of the laser anti-counterfeiting layer in a laminating mode; the lining paper layer is attached to the matte surface of the aluminum foil layer; the paper board layer is attached to the outer surface of the lining paper layer; and the shading material layer is applied to the outer surface of the paper board layer in a coating mode. According to the laser anti-counterfeiting material used for medicine packaging, aqueous laser transfer coating is adopted, volatilization of toxic gases of oily transfer coating in the drying process is avoided, the obtained packaging material is suitable for packaging products which people can directly eat, and the requirement of green production is met. A processing method of the laser anti-counterfeiting material is high in finished product rate and suitable for market promotion. The laser anti-counterfeiting material has the shading property, thereby being suitable for packaging medicine products needing to be kept in a dark place.

Description

technical field [0001] The invention belongs to the technical field of packaging materials, and in particular relates to a laser anti-counterfeiting material used for medicine packaging and a processing technology thereof. Background technique [0002] Laser anti-counterfeiting technology is to use laser light source to record the light wave amplitude information and corresponding information at the same time in a very short time, and use the interference principle of light to reflect each particle that constitutes the image, and make a unique anti-counterfeiting plate, so as to achieve the purpose of anti-counterfeiting . [0003] At present, in order to ensure product quality, various manufacturers apply laser anti-counterfeiting technology to product packaging or directly to products to prevent counterfeit products from destroying corporate image. Especially for the high-end tobacco, wine and pharmaceutical packaging industries, the appearance of counterfeit cigarettes, ...

AI Technical Summary

Problems solved by technology

The application of laser anti-counterfeiting technology to packaging materials is mainly based on the working principle of film transfer. The whole work process includes plate making, film formation, film transfer and peeling. There are still problems such as incomplete film transfer and unclean peeling in the whole process; With the intensification of environmental pollution, people's awareness of environmental protection is getting stronger and stronger, and the requirements for green packaging materials are getting higher and higher. Therefore, while ensuring that packaging materials have anti-counterfeiting properties, they are also required to be naturally degradable. Maintain the sustainable development of the earth; in addition, in the packaging of medicines, because most medicines need to be stored in the dark, the use of ordinary packaging paper cannot achieve the ideal effect of light-proof storage, so an anti-counterfeiting packaging material with good light-shielding effect is needed
