Disposable laser holographic false proof seal

Abstract

A one-off laser holographic anti-fake seal pertains to the field of fabrication technology of laser holographic anti-fake packing materials, and mainly comprises a base film layer (8), a local release layer (7) compounded on the front of the base film layer (8) sequentially from down to up, an imaging layer (6), a laser holographic information layer (5), an anti-fake ink layer (4), an aluminized layer (3), an engraved local protecting layer (1), a glue-coating layer (2), an anti-sticking layer (9) compounded on the back of the base film layer (8), etc. The design of the integral structure is reasonable, the laser holographic anti-fake technology and means are used, the specific patterns are presented after engraved by the engraved local protecting layer, and the technical difficulty is increased; the present invention is characterized in aesthetic appearance, direct and easy identification, and widely application in sealing chamber, sealing storage and sealing open based on paper, wood, plastic and metal materials, thus providing reliable products and technology guarantee for the seal pasting of product forgery prevention, administrative enforcement and transportation.

Description

technical field [0001] The invention relates to a disposable laser holographic anti-counterfeit seal, which belongs to the technical field of manufacturing laser holographic anti-counterfeit packaging materials. Background technique [0002] As we all know, in addition to the fixing function, the seal is also required to have the function of anti-sealing and detection of whether it has been sealed in special occasions. However, the existing commonly used seals have low technical requirements, are easy to make, and are easy to replace and restore after unsealing, which brings many difficulties to anti-counterfeiting and anti-counterfeiting. There are also integral transfer types, but counterfeiters can often cover them with fully transparent adhesive film or scotch tape, which is similar to restoration, and is also easy to be counterfeited. Contents of the invention [0003] The object of the present invention is to provide a disposable laser holographic anti-counterfeit s...
