Description

LDPE (Low-Density polyethylene) gold stamping film

Technical Field

The utility model relates to a gilt membrane technical field, concretely relates to LDPE scalds golden membrane.

Background

The traditional gold stamping process is only suitable for paper and high-temperature-resistant films, so that the gold stamping process is not suitable for all packaging schemes. In addition, when the traditional gold stamping process is used for LDPE films, the surface of the LDPE films cannot be transferred well.

Disclosure of Invention

The utility model aims at overcoming the above-mentioned not enough, providing a LDPE gilding film, gilding effect can present at LDPE rete surface perfection, makes the pattern on the wrapping bag that is formed by this LDPE gilding film more high-end pleasing to the eye, promotes the product grade, makes traditional gilding technology be applicable to all packing schemes.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a LDPE scalds gold membrane, includes top-down complex gold foil transfer layer and LDPE rete in proper order, gold foil transfer layer by the PET thin layer and scribble in the coloured aluminum powder layer of PET thin layer lower surface constitutes, LDPE rete upper surface is the corona treatment face, the printing has the printing ink layer on the corona treatment face of LDPE 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.

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

1. the utility model relates to a LDPE scalds golden membrane makes gilt effect present at LDPE rete surface perfection, makes the pattern on the wrapping bag by this LDPE gilt membrane formation more high-end pleasing to the eye, promotes the product grade.

2. The utility model relates to a LDPE scalds gold film 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 LDPE scalds golden membrane and makes packaging scheme display effect have multiple colour to select.

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

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

The correspondence between each mark and the part name is as follows:

1. a gold foil transfer layer; 2. an ink layer; 3. an LDPE film layer.

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 figure 1, a LDPE scalds gold film, includes top-down complex gold foil transfer layer 1 and LDPE rete 3 in proper order, gold foil transfer layer by the PET thin layer and scribble in the coloured aluminum powder layer of PET thin layer lower surface is constituteed, LDPE rete upper surface is the corona treatment face, printing ink layer 2 has on LDPE rete 3's the corona treatment face.

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

Wherein, the thickness of the ink layer 2 is 0.0005 to 0.003 mm.

The gold foil transfer layer 1 in the LDPE bronzing film in the embodiment has good transferability and high brightness, so that the bronzing effect of the composite bronzing film in the embodiment can be perfectly presented on the surface of the LDPE film layer 2, and meanwhile, when the composite bronzing 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 layer in the LDPE hot stamping film can be changed according to the requirement of the packaging scheme, so that the LDPE hot stamping film in this embodiment enables the display effect of the packaging scheme to be selected by a plurality of colors.

The step of performing gold stamping treatment on the LDPE gold stamping film in the embodiment by the gold stamping process is as follows: and installing a zinc laser engraving template on a 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 the gold powder layer of the gold stamping foil is transferred to the printing surface of the LDPE film layer 3 through the gold foil transfer layer 1.

The LDPE bronzing film in the embodiment can be used in the fields of plastic packaging of sanitary products (such as sanitary towels, paper diapers, pet pads and mother and infant products), food packaging, clothing packaging, industrial product packaging and the like.

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