In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a compound gold stamping film, includes top-down complex gold foil transfer layer, extinction PE rete, opal PE rete in proper order, the gold foil transfer layer by the PET thin layer and scribble in the coloured aluminium powder layer of PET thin layer lower surface is constituteed, extinction PE rete lower surface is the corona treatment face, the printing has the printing ink layer on the corona treatment face of extinction PE rete, the printing ink layer with it has the gluing layer to fill between the opal PE rete.

Further, the thickness of the colored aluminum powder layer is 0.002 mm.

Further, the thickness of the ink layer is 0.0005 to 0.003 mm.

Further, the thickness of the adhesive layer is 0.0005 to 0.003 mm.

Compared with the prior art, the beneficial effects of the utility model reside in that:

1. the utility model relates to a compound gilt membrane makes gilt effect present at extinction PE rete and opal PE rete surface perfection.

2. The utility model relates to a compound gilt membrane is applicable to all packing schemes, consequently makes traditional gilt technology also be applicable to all packing schemes, has satisfied all packing schemes and has satisfied the pleasing to the eye requirement of high-end.

3. The utility model relates to a compound gilding membrane makes packing scheme display effect have multiple colour to select.

4. The utility model relates to a compound gilding membrane accords with national environmental protection requirement, and recycle is convenient.

5. The utility model relates to a compound bronzing film is used for the wrapping bag preparation to improve wrapping bag packing feel.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

As shown in fig. 1, a composite gold stamping film comprises a gold foil transfer layer 1, an extinction PE film layer 2 and a milky-white PE film layer 3 which are sequentially compounded from top to bottom, wherein the gold foil transfer layer 1 comprises a PET film layer and a colored aluminum powder layer coated on the lower surface of the PET film layer, the lower surface of the extinction PE film layer 2 is a corona treatment surface, an ink layer 4 is printed on the corona treatment surface of the extinction PE film layer 2, and an adhesive layer 5 is filled between the ink layer 4 and the milky-white PE film layer 3.

Wherein the thickness of the colored aluminum powder layer is 0.002 mm.

Wherein, the thickness of the ink layer 4 is 0.0005 to 0.003 mm.

Wherein the thickness of the adhesive layer 5 is 0.0005 to 0.003 mm.

The gold foil transfer layer 1 in the composite gold stamping film in the embodiment has good transferability and high brightness, so that the gold stamping effect of the composite gold stamping film in the embodiment can be perfectly presented on the surfaces of the extinction PE film layer 2 and the milky PE film layer 3, and meanwhile, when the composite gold stamping film is used for a packaging bag, the surface of the packaging bag can have a high-texture metal effect, and the packaging texture of the packaging bag is improved.

In this embodiment, the color of the colored aluminum powder in the colored aluminum powder layer in the composite bronzing film can be changed according to the requirements of the packaging scheme, so that the display effect of the packaging scheme can be selected by the composite bronzing film in this embodiment.

The processing and preparation steps of the composite bronzing film in the embodiment are as follows:

s1, printing an ink layer 4 on the corona treatment surface of the extinction PE film layer 2;

s2, connecting the printing ink layer 4 on the corona treatment surface of the delustering PE film layer 2 with the milky PE film layer 3 through an adhesive layer 5;

s3, compounding the gold foil transfer layer 1 on the upper surface of the extinction PE film layer 2;

s4, placing the composite gold stamping film compounded in the step S3 in a curing chamber at 35 ℃ for curing, and after the curing reaction of the adhesive in the adhesive layer 5 is over 5 percent (about 72-84 hours), finishing the processing and manufacturing after the inspection of the composite curing requirement.

The steps of performing gold stamping treatment on the composite gold stamping film in the embodiment by the gold stamping process are as follows: and installing a zinc laser engraving template on a gold stamping machine, heating the zinc laser engraving template to 140 ℃, and then heating the gold stamping foil by using the zinc laser engraving template, so that a gold powder layer of the gold stamping foil is transferred to a non-printing layer of the extinction PE film layer 2 through the gold foil transfer layer 1.

The composite gold stamping film in the embodiment can be used in the field of plastic packaging of sanitary products (such as sanitary towels, paper diapers, pet pads and mother and baby products), food packaging, clothing packaging, industrial product packaging and the like.

When the composite bronzing film in the embodiment is used for a sanitary towel packaging bag, the printed patterns are high in brightness and metallic color, the softness of single-film PE packaging is kept, and the bronzing film can also be used for a fused edge bottom sealing folded edge bag of the sanitary towel packaging bag.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
