Description

TECHNICAL FIELD

[0001] The utility model relates to printing packaging material technical field, concretely relates to a kind of electrochemical aluminum stamping foil, and it is especially applicable to the anti-gold flying electrochemical aluminum stamping foil for reducing gold flying phenomenon in high-speed stamping process. BACKGROUND

[0002] The electrochemical aluminum stamping foil is generally composed of a base film layer, a release layer, a coloring layer, an aluminum plating layer and an adhesive layer. Under the action of heat pressing, the adhesive layer melts and adheres to the surface of the printing material. After peeling, the coating layer is separated from the base film. Finally, the coating layer is transferred to the printing material by the stamping die to form a stamping layer with metallic texture.

[0003] However, during the stamping process, the edge of the heated stamping die will have an effect on the coating layer of the electrochemical aluminum stamping foil, causing the edge of the electrochemical aluminum stamping foil coating layer to become loose. When the coating layer is separated from the base film, it is transferred to the surface of the printing material, becoming a burr at the edge of the stamping layer. The burr at the edge of the stamping layer is not firmly bonded and can be easily removed by slight external force. This is known as the gold flying phenomenon, which is a common quality problem during the electrochemical aluminum stamping process. It can produce a large amount of waste products. SUMMARY

The composite release layer 2 and the coloring layer 3 are fully coated with a transparent anti-gold flying functional layer 6.

[0006] Preferably, the upper surface of the aluminum plating layer 4 is provided with an anti-aluminum stripping functional layer 7, and the other side of the anti-aluminum stripping functional layer 7 is attached to the adhesive layer 5. The anti-aluminum stripping functional layer 7 is a coupling agent layer, which can form a strong bonding force with the aluminum plating layer 4 and the adhesive layer 5, thereby having good adhesion.

[0007] Preferably, the upper surface of the composite release layer 2 is provided with a high-gloss wear-resistant layer 8, and the other side of the high-gloss wear-resistant layer 8 is attached to the transparent anti-gold flying functional layer 6.

[0008] The BOPET film layer 1 has a thickness of 12 μm, which supports other coating layers and has properties such as high temperature resistance, transparency, solvent resistance, etc.

[0009] The composite release layer 2 is a wax release material mixed with a water-based resin layer, mainly playing a peeling role, so that each coating layer on the aluminum foil can be transferred to the surface of the material to be printed, and the wet coating amount is 3.8-4.0g / m 2 .

[0010] The transparent anti-flying gold functional layer 6 is a transparent acrylic resin layer, and the dry coating amount is 0.2-0.5g / m2, which plays a protective role on the coloring layer 3.

[0011] The coloring layer 3 is a thermosetting coloring layer composed of polyurethane resin, curing agent resin and colorant, which is a layer determining the main performance of the aluminum color, brightness, cutting property and wear resistance, and the dry coating amount is 1.0-1.2g / m 2 .

[0012] The aluminum plating layer 4 is a vacuum aluminum plating layer, which plays a role in making the film emit a shiny metallic luster, which is the effect pursued by gold stamping, and the optical density value of the vacuum aluminum plating is 1.40-1.60.

[0013] The adhesive layer 5 is composed of hot melt adhesive, and the dry coating amount is 1.0-1.15g / m 2 , which plays a role in bonding each coating layer of the aluminum foil to the material to be printed.

[0014] The electric aluminum foil has the advantages that: the transparent anti-flying gold functional layer is adopted, the acrylic resin is transparent, the coloring layer is protected, and the anti-flying gold effect is achieved.

[0015] The aluminum plating layer 4 and the adhesive layer 5 are provided with the anti-aluminum peeling functional layer 7, the anti-aluminum peeling functional layer 7 can form strong bonding force with the aluminum plating layer 4 and the adhesive layer 5, the high light wear-resistant layer 8 improves the transparency and gloss of the electric aluminum foil.

[0016] The thermosetting coloring layer contains acrylic resin and adhesion promoting resin similar to the structure of the transparent anti-flying gold functional layer, and effectively improves the adhesion of the coloring layer to the base film layer, the transparent anti-flying gold functional layer and the vacuum aluminum plating layer.
