Problems solved by technology

In this way, the anti-counterfeiting trademark of the enterprise will lose its anti-counterfeiting effect and significance, causing huge economic losses and immeasurable serious consequences to the enterprise, and also seriously damaging the interests of consumers and affecting the market order.
2. Use embedded anti-counterfeiting materials (ultraviolet ink anti-counterfeiting materials, laser holographic anti-counterfeiting materials, precision printing anti-counterfeiting materials, pattern anti-counterfeiting materials, light angle color-changing anti-counterfeiting materials or polymer holographic anti-counterfeiting materials, etc.) for anti-counterfeiting, due to the high penetration rate of all anti-counterfeiting materials , low market exclusivity, simple manufacturing process greatly reduces its anti-counterfeiting strength
3. Using printed QR codes for anti-counterfeiting, the disadvantage is that because the printed QR codes are fixed, it is easy for counterfeiters to carry out counterfeit printing, so that consumers cannot distinguish the authenticity and bring losses to consumers.

Abstract

The invention belongs to the technical field of anti-counterfeiting packages and particularly relates to a digital holographic anti-counterfeiting glue cap and a preparation method thereof. The digital holographic anti-counterfeiting glue cap comprises a glue cap and a thermally-printed foil layer, wherein the glue cap, a printing layer, an aqueous priming coat and the thermally-printed foil layer are sequentially connected, and the thermally-printed foil layer is transferred to the glue cap in a cramping manner. The preparation method comprises the steps of material selection, designing, plate-making, mold pressing, printing, aluminum washing, printing layer coating, code printing, coating transfer, slitting, forming. According to the preparation method, digital holographicanti-counterfeiting thermally-printed foil is transferred to a fixed position of the glue cap by virtue of a cramping transfer technique, so that the holographic and digital anti-counterfeiting techniques are integrated; as the number of anti-counterfeiting characteristics is large, the anti-counterfeiting capability is improved; an anti-counterfeiting mark is replaced by virtue of the digital holographic anti-counterfeiting glue cap so as to achieve an untransferable purpose, and a positioning transfer method of the thermally-printed foil on a PVC (Polyvinyl Chloride) material is realized.

Description

technical field [0001] The invention belongs to the technical field of anti-counterfeiting packaging, in particular to a digital holographic anti-counterfeiting rubber cap and a preparation method thereof. Background technique [0002] At present, all kinds of bottled wines on the market usually use heat-shrinkable plastic caps that prevent secondary use to play an anti-counterfeiting role. Heat shrinkage makes the rubber cap fit closely with the shape of the bottle body. In order to suppress counterfeiting, the following anti-counterfeiting methods are now taken: 1. The method of pasting anti-counterfeiting trademarks is used for anti-counterfeiting. An opportunity to take advantage of. Consumers often only destroy the plastic cap when opening the wine bottle, leaving the anti-counterfeiting trademark intact on the waste rubber cap. Counterfeiters recycle these waste rubber caps with anti-counterfeiting trademarks at high prices, and then cut off the anti-counterfeiting t...
