A quasi-dynamic bubble glass anti-counterfeiting label with random three-dimensional graphics and its preparation method

Abstract

The invention discloses a quasi dynamic bubble glass random stereo graph anti-counterfeiting label and a preparation method thereof. The preparation method comprises the steps of preparing a light guide plate layer, and randomly cutting the layer into a weak mechanical connection structure; preparing a bubble glass layer, and randomly cutting the layer into a weak mechanical connection structure; fabricating a random graphic information enhancement layer; bonding the random graphic information enhancement layer to the bubble glass layer with adhesive; printing a graph layer on the surface of the random graphic information enhancement layer; bonding the light guide plate layer to the lower surface of the bubble glass layer; installing light-emitting elements to the side faces of the light guide plate layer; connecting the light-emitting elements with power lines, and connecting the power lines with a battery; arranging the light guide plate layer, the bubble glass layer, the random graphic information enhancement layer and the graph layer in sequence from bottom to top. The quasi dynamic bubble glass random stereo graph anti-counterfeiting label is high in anti-counterfeiting intensity and has wide application prospect in multiple commodity anti-counterfeiting fields such as tobacco and wine, food, medicine, health care products, cosmetics, clothes, pesticide, fertilizers, automobile components and parts and seeds.

Description

technical field [0001] The invention belongs to the technical field of anti-counterfeiting, and in particular relates to an anti-counterfeiting label with random three-dimensional graphics of quasi-dynamic bubble glass and a preparation method thereof. Background technique [0002] With the rapid development of the market economy, the market is flooded with all kinds of counterfeit products and brand-name products. In order to protect their own rights and interests of consumers, merchants are becoming more and more aware of the protection of brands and intellectual property rights, and have put forward higher and higher requirements for anti-counterfeiting technology. There are many kinds of anti-counterfeiting technologies, such as laser holography, watermarking, code technology, digital coding, bar code, two-dimensional code and RFID. [0003] These anti-counterfeiting technologies and anti-counterfeiting labels generally have the following problems: (1) Although dynamic ...
