Embodiment 1

[0068] The laser encryption anti-counterfeiting transfer film includes a PET base film layer, a transfer coating layer, a laser encryption information layer, an aluminum layer, an alkali-resistant varnish layer and a surface coating layer arranged in sequence from top to bottom, and the laser encryption information layer Contains hidden information, which is revealed under point light sources.

[0069] The transfer coating is a transferable thermoplastic acrylic resin layer, and the dry coating weight is 1.2g / m 2 . The transfer coating and the PET base film are peeled off with 3M adhesive tape, and can be separated at any speed.

[0070] The digital coding information is hidden in the laser encryption information layer.

[0071] The thickness of the aluminum layer is

[0072] The alkali-resistant varnish layer has a dry coating weight of 0.6g / m 2 , Effectively protect the covered aluminum layer from being washed off by lye.

[0073] The surface coating, the dry coating ...

Abstract

The invention belongs to the field of anti-counterfeiting technology products, and particularly relates to a laser encryption anti-counterfeiting transfer film and a preparation method of the laser encryption anti-counterfeiting transfer film. The anti-counterfeiting transfer film comprises a PET base film layer, a transfer coating, a laser encryption information layer, an aluminum layer, an alkali-resistant gloss oil layer and a surface coating which are sequentially arranged from top to bottom, wherein the laser encryption information layer comprises hidden information, and the hidden information appears under a point light source. The laser encryption anti-counterfeiting transfer film is provided with the laser encryption information layer, a digital coding information grating structureis hidden in the laser encryption information layer, under the natural light, the encryption information is hidden, handheld spot light source equipment is used to irradiate the transfer film, the hidden information is presented, consumers judge the authenticity of the products by identifying the hidden information, and the consumers can inquire the authenticity conveniently; a mathematical algorithm is used for encryption, the anti-counterfeiting strength is high, the counterfeiting is not easily cracked, and the imitation difficulty is increased; and the preparation method is scientific andreasonable and is simple and easy to implement.

Description

technical field [0001] The invention belongs to the field of anti-counterfeiting technical products, and in particular relates to a laser-encrypted anti-counterfeiting transfer film and a preparation method thereof. Background technique [0002] The anti-counterfeiting transfer film can directly transfer holographic information to the packaging substrate, and is often used in the packaging of cigarette packs, wine packs, cosmetics, medicine, and high-end gifts. The transfer film currently on the market has a simple structure and a single function, and is easy to forge. [0003] Laser embossed holographic anti-counterfeiting technology was introduced into my country in the late 1980s and early 1990s. Especially from 1990 to 1994, hundreds of production lines were introduced all over the country, accounting for more than half of the world's manufacturers at that time. At the beginning of the introduction, this anti-counterfeiting technology did play a certain role in anti-cou...
