Detailed Description

The present invention is further described in detail below with reference to examples so that those skilled in the art can implement the invention with reference to the description.

As shown in fig. 1, the present embodiment provides a color laser composite film for personalized printing, which includes a transparent mechanical strength layer 1, a laser printing layer 2, an adhesive layer 3, and a light shielding layer 4, which are sequentially disposed from top to bottom;

the laser printing layer 2 includes a base layer 21 having opposite first and second surfaces; a plurality of first bulges 22 are arranged on the first surface at intervals, and a plurality of second bulges 23 are arranged on the second surface at intervals;

the second protrusions 23 correspond to the first protrusions 22 in interval, that is, the first protrusions 22 and the second protrusions 23 are alternately and complementarily arranged; the first bulge 22 is provided with a first printing layer, the second bulge 23 is provided with a second printing layer, the first printing layer is printed with a first image 24, the second printing layer is printed with a second image 25, and the first image 24 and the mirror image of the second image 25 form a complete image.

The base layer 21, the first protrusions 22 thereon, and the second protrusions 23 thereon are made of a transparent material, and the transparent material may be a transparent PC film.

Further, the first protrusion 22 and the second protrusion 23 are both in a strip shape, and the first protrusion 22 and the second protrusion 23 are respectively provided with a first printing layer and a second printing layer.

In this embodiment, the first printing layer and the second printing layer are both UV paint layers, and the first image and the second image are both color laser images. Wherein, the color laser image is printed on the UV paint layer by adopting a laser pattern imprinting transfer technology.

Wherein, first printing layer and second printing layer adopt laser pattern impression transfer technique to form, and its technical principle is: and (3) coating UV gloss oil on the surface of a printed matter, compounding the UV gloss oil with a prefabricated laser pattern transfer film under the pressure action of a laser pattern imprinting transfer machine, and peeling the laser pattern transfer film from a product after the UV gloss oil is quickly cured and qualified under the irradiation of ultraviolet light. Thus, a glittering pattern corresponding to the laser pattern transfer film is formed on the surface of the product where the UV varnish is coated. This technique achieves a variety of different color laser printing effects without damaging the composite film.

In this embodiment, the first print layer is printed with a first image 24, and the second print layer is printed with a second image 25; wherein the mirror image of the first image 24 and the second image 25 constitute a complete image, i.e. the first image 24 is normally printed and the second image 25 is printed in mirror image with respect to the first image 24, such that viewing the first image 24 and the second image 25 simultaneously is arranged to see a complete image consistent with the design.

In addition, the first protrusions 22 and the second protrusions 23 are arranged on the opposite surfaces and are arranged in an alternating and complementary manner, so that the pattern can be completely seen only when the pattern is vertically viewed, and only a part of the pattern can be seen when the pattern is obliquely viewed, thereby providing an anti-counterfeiting function.

Further, the complete pattern is formed by the first image 24 and the second image 25, so that the pattern is not good for reproduction, further improving the anti-counterfeiting function.

The transparent mechanical strength layer 1 is a biaxially oriented polyester film, the thickness of the transparent mechanical strength layer is 12-15 microns, the transparent mechanical strength layer has good heat resistance and excellent tensile strength, deformation is avoided in the processing process, and the temperature of a heat sealing ironing knife can be increased during high-speed packaging so as to increase the packaging speed.

The adhesive layer 3 is a two-component polyurethane adhesive, which can provide good adhesion to the composite film layer.

The light shielding layer 4 is a polyester aluminized film or an aluminum foil or polyethylene or polypropylene, and has the functions of shielding light and preventing ultraviolet radiation.
