Abstract

The invention provides a tamper-evident label with functions of a laser holography label and a two-dimensional bar code and a preparation method of the tamper-evident label. The tamper-evident label comprises a base film layer, an embossed information layer, a metal reflecting layer, a hollowed-out print layer, a protective layer, a digital printing layer and an adhesive sticker layer in the sequence from top to bottom. The preparation method comprises the following steps: coating the base film layer with the embossed information layer, and carrying out drying and curing; carrying out embossing by an embossing machine, so that holographic patterns are copied to the embossed information layer; plating the metal reflecting layer in a winding-type vacuum coating machine; printing the specially-made hollowed-out print layer on the metal reflecting layer; coating the whole hollowed-out print layer with the protective layer; printing the two-dimensional bar code containing various information; coating an adhesive sticker; compounding with semitransparent silicone oil paper; carrying out die cutting; carrying out slitting; carrying out inspection; and putting into storage. For the tamper-evident label, the laser holography anti-counterfeiting function and various variable data information extraction functions are simultaneously obtained, in addition, the function of preventing the label from being torn through an improper means so as to further avoid the malicious bar code scanning is also provided, and the label has the advantages of anti-counterfeiting property, tamper-evident property and disposable use property.

Description

technical field [0001] The invention relates to a preparation process of a holographic anti-counterfeit label, more specifically, an anti-tampering label having both a laser holographic label and a two-dimensional code and a preparation method thereof, belonging to the technical field of anti-counterfeiting devices. Background technique [0002] In the era of big data, two-dimensional codes are the key means to realize the tracking of the Internet of Things, and laser holography, as an important means of anti-counterfeiting, has been widely used in various fields. Combining laser holographic anti-counterfeiting and two-dimensional codes, an anti-counterfeiting mark with both laser holographic marks and two-dimensional codes is prepared. Realize product information management. The holographic two-dimensional code product has created a precedent in the industry and has become a new navigation mark in the industry. [0003] However, as an early anti-counterfeiting label, the ...
