Description

Technical Field

[0001] The utility model relates to the technical field of packaging, in particular to an anti-counterfeiting laser draw line. Background Art

[0002] Anti-counterfeiting laser wires are widely used in making various promotional materials, billboards, labels, packaging boxes, etc. The structure of the anti-counterfeiting laser wires on the market is relatively complex, usually composed of an anti-adhesive layer, an original film layer, a first aluminum layer, an information layer, a laser layer, a second aluminum layer and an adhesive layer arranged in sequence. The first aluminum layer is coated with ink to form an information layer with anti-counterfeiting graphics. The brightness of the anti-counterfeiting laser wires with this structure is not high, and the anti-counterfeiting effect is poor.

[0003] Therefore, it is very necessary to improve the structure of the existing anti-counterfeiting laser pull line and design an anti-counterfeiting laser pull line with higher brightness and better anti-counterfeiting effect. Utility Model Content

The colors of the first anti-counterfeiting graphics, the second anti-counterfeiting graphics, and the third anti-counterfeiting graphics are different.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The anti-counterfeiting laser pull line of the utility model comprises an original film layer, an aluminum-plated layer, a laser information layer and a glue layer which are arranged in sequence, and does not need to be arranged with a printing color ink layer, so the cost is low, the structure is simple, the brightness is high, and the anti-counterfeiting effect is good; the utility model arranges the laser information layer on the aluminum-plated layer, so as to avoid directly performing a molding process on the original film layer to form the laser information layer and deforming the original film layer; the glue layer is directly arranged on the laser information layer, so as to well protect the laser information layer and the aluminum-plated layer.

[0017] In order to better illustrate the purpose, technical solutions and advantages of the present invention, the present invention will be further described below in conjunction with specific embodiments.

[0018] See also Figure 1 The utility model provides an anti-counterfeiting laser pull wire, comprising an original film layer 1, an aluminum-plated layer 2, a laser information layer 3 and an adhesive layer 4 which are arranged in sequence, the aluminum-plated layer 2 covers one side of the original film layer 1, the laser information layer 3 covers the side of the aluminum-plated layer 2 away from the original film layer 1, and the adhesive layer 4 covers the side of the laser information layer 3 away from the aluminum-plated layer 2.

[0019] In one embodiment, the thickness of the original film layer 1 is 12-36 μm.

[0020] The original film layer 1 is a polyethylene terephthalate (PET) film, which has high transparency, high tensile strength and small deformation.

[0021] In one embodiment, the thickness of the aluminum plating layer 2 is 300-400 angstroms.

[0022] In one embodiment, the adhesive layer 4 is a pressure-sensitive adhesive layer.

[0023] The thickness of the adhesive layer 4 is 3-10 μm.

[0024] This pressure-sensitive adhesive layer of a specific thickness not only has good adhesion, but the anti-counterfeiting laser pull line of the utility model can be self-adhesive to the surface of various packaging products through the pressure-sensitive adhesive, and can also play a good protective role on the laser information layer 3.

[0025] In one embodiment, a release layer 5 is provided on the side of the original film layer 1 away from the aluminum-plated layer 2. The release layer 5 is a silicone oil release layer. The thickness of the release layer 5 is 0.5-2 μm. The silicone oil release layer has a good release effect and is convenient for unwinding the anti-counterfeiting laser wire.

[0026] In one embodiment, the laser information layer 3 is inlaid with anti-counterfeiting graphics, which include a first anti-counterfeiting graphics, a second anti-counterfeiting graphics, and a third anti-counterfeiting graphics. The color of the first anti-counterfeiting graphics, the color of the second anti-counterfeiting graphics, and the color of the third anti-counterfeiting graphics are different. For example, the color of the first anti-counterfeiting graphics is red, the color of the second anti-counterfeiting graphics is gold, and the color of the third anti-counterfeiting graphics is blue.

[0027] Compared with the prior art, the anti-counterfeiting laser pull line of the utility model is composed of an anti-sticking layer 5, an original film layer 1, an aluminum-plated layer 2, a laser information layer 3 and an adhesive layer 4 which are arranged in sequence. The laser holographic special edition image and text are printed on the aluminum-plated layer 2 through the existing hard pressing molding process to form a laser information layer 3 inlaid with anti-counterfeiting images and texts. There is no need to set a printing color ink layer, so the cost is low, the structure is simple, the brightness is high, and the anti-counterfeiting effect is good.

[0028] The utility model arranges the laser information layer 3 on the aluminum-plated layer 2 to avoid directly performing molding processing on the original film layer 1 to form the laser information layer 3 and deforming the original film layer 1; and arranges the adhesive layer 4 directly on the laser information layer 3 to well protect the laser information layer 3 and the aluminum-plated layer 2.

[0029] In an actual application scenario, the utility model uses a polyethylene terephthalate (PET) film with a thickness of 25 μm as the original film layer 1, forms an aluminum-plated layer 2 with a thickness of 400 angstroms on the original film layer 1 through the existing vacuum aluminum plating process, and then forms a laser holographic special edition by hard pressing, and forms a laser information layer 3 with anti-counterfeiting graphics on the aluminum-plated layer 2. The anti-counterfeiting graphics include a first anti-counterfeiting graphics in red, a second anti-counterfeiting graphics in gold, and a third anti-counterfeiting graphics in blue. A pressure-sensitive adhesive layer with a thickness of 6 μm is superimposed on the laser information layer 3, and anti-sticking silicone oil is coated on the side of the original film layer 1 away from the aluminum-plated layer 3. After the anti-sticking is cured, an anti-sticking layer 5 with a thickness of 0.5 μm is formed. Finally, the anti-counterfeiting laser wire with a width of 2.5 mm and a length of 10,000 m is obtained by slitting and cutting. Under light irradiation, the anti-counterfeiting graphics of the anti-counterfeiting laser wire are clear, the laser effect is good, and the anti-counterfeiting effect is good.

Therefore, the features defined as "first", "second", and "third" may explicitly or implicitly include one or more of the features.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
