Digital holographic anti-counterfeiting glue cap and preparation method thereof

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...
