Embodiment 2

[0036] Such as figure 2 As shown, the disposable laser anti-counterfeiting label 2 of the present embodiment includes a base film 22, an anti-counterfeiting code 12 printed on the base film 22, a laser holographic layer 32 coated on one surface of the base film 22, and a The aluminum layer 42 on the laser information layer 32, the pressure-sensitive adhesive layer 52, and the substrate layer coated with silicon paper 62. in:

[0037] The anti-counterfeit code layer 12 is a variable anti-counterfeit code such as a one-dimensional code, a two-dimensional code or a three-dimensional code.

[0038] The base film 22 is a 30-50um thick PVC / PET film;

[0039] The laser holographic information layer 32 adopts water-based or solvent-based transfer coating, the solid content of the transfer coating is 20-25%, the softening point is 120-135°C, the acid value is 15-30mg KOH / g, and the dry coating amount is 1.5-2.5 g / m 2 .

[0040] The aluminum layer 42 has a thickness of 300, 350, 4...

Embodiment 3

[0043] Embodiment three, the manufacture of disposable laser anti-counterfeit label 1 and 2:

[0044] Such as image 3 As shown, the specific process steps for manufacturing disposable laser anti-counterfeiting labels 1 and 2 are as follows:

[0045] Step 1: First, use PVC / PET film (1 or 12) to coat the holographic laser coating layer (2 or 22) on the coating machine, and then use infrared drying and curing to form a coating film;

[0046] Step 2: Carry out holographic molding on the coating film on a laser molding machine to form a laser holographic film;

[0047] Step 3, using a vacuum aluminum coating machine to plate an aluminum layer (3 or 32) on the coating surface of the laser film, the thickness of the aluminum layer is 300 to 500 angstroms, forming an aluminum-coated laser film;

[0048] Step 4, using a code jet printing machine to print variable anti-counterfeit codes (4 or 42) on the aluminum-plated surface (3a) or the PVC / PET film surface (12b);

[0049] Step 5, c...

Abstract

The invention provides a disposable laser anti-counterfeiting label. The disposable laser anti-counterfeiting label is characterized by comprising a base film layer, a laser holographic transferring coating, a metal plating layer, an anti-counterfeiting code layer, a pressure-sensitive adhesive layer and a lining layer, wherein the base film layer, the laser holographic transferring coating, the metal plating layer, the pressure-sensitive adhesive layer and the lining layer are arranged in sequence from inside to outside; the anti-counterfeiting code layer is arranged on the inner side of the base film layer; or the anti-counterfeiting code layer is arranged between the metal plating layer and the pressure-sensitive adhesive layer. The anti-counterfeiting label provided by the invention is adhered to a commodity or an outer package and a laser anti-counterfeiting pattern and an anti-counterfeiting code are damaged when the label is uncovered; the label cannot be repeatedly utilized and is not easy to counterfeit; the high anti-counterfeiting property of commodity anti-counterfeiting identification and the reality of the commodity can be met.

Description

technical field [0001] The invention relates to a one-time application anti-counterfeiting technology of a laser anti-counterfeiting label, in particular to a one-off laser anti-counterfeiting label and a manufacturing method thereof. Background technique [0002] In order to improve the authenticity of various commodities, manufacturers often use a variety of anti-counterfeiting means to carry out anti-counterfeiting marks on commodities, and anti-counterfeiting labels are one of the types. However, the current anti-counterfeiting labels are easy to copy or can be reused, and cannot fully achieve the anti-counterfeiting identification effect of commodity authenticity verification. There is an urgent need for a non-reproducible or non-reusable high-anti-counterfeit label to carry out anti-counterfeiting identification of commodities. Contents of the invention [0003] The present invention aims to overcome the defects in the prior art and provide a disposable laser anti-c...
