Problems solved by technology

In traditional printing, the amount of ink in offset printing is the least, and it is impossible to realize it from the process. The amount of ink in gravure printing can meet the requirements theoretically, but this time will bring another problem. When such a large amount of The ink is directly printed on the paper. During the drying process, the paper may have been deformed, making it impossible to print the subsequent color group. It is even possible that the paper will be broken due to the serious deformation of the paper when the ink is printed, making it impossible to print.
Even if the paper is relatively thick and can withstand ink penetration without deformation, the use of the paper will be limited. At the same time, thicker ink is directly printed on the surface of the paper, which may cause poor ink leveling

Embodiment 1

[0026] figure 1 It is a structural representation of frosted silver cardboard of the present invention, as figure 1 As shown, the frosted silver cardboard comprises a base paper layer 1, an adhesive layer 2 coated on one side surface of the base paper layer 1, an frosted silver layer 3 coated on the adhesive layer 2, and coated on The surface coating on the frosted silver layer 3, in this embodiment, the surface coating is a transparent acrylic paint layer 4.

[0027] The base paper layer 1 can be coated paper, white cardboard with white core, white cardboard with yellow core or white cardboard with gray background, and the weight ranges from 80 to 350g / m 2 , preferably 200-230g / m 2 White core white cardboard. Base paper layer 1 in the present embodiment adopts 225g / m 2 white cardboard with white core.

[0028] Adhesive layer 2 adopts polymerized styrene-butadiene emulsion.

[0029] The frosted silver layer 3 is formed by coating with frosted silver paste. The frosted si...

Embodiment 2

[0037] In the second embodiment, coated paper is used as the base paper layer.

[0038] The manufacturing method of the frosted silver cardboard of the present embodiment comprises the following steps:

[0039] Step 1: First use a BOPET film with a thickness of 14 μm, and coat a transparent acrylic paint on a coating machine at a speed of 100 m / min, with a dry weight of 1.2 g / m 2 . The acrylic paint is dried and cured at 120° C. to obtain the acrylic paint layer 4 , and the acrylic paint layer 4 and the BOPET film are collectively called a coating film; forming a coating film.

[0040] Step 2, on the coating surface of the coating film obtained in step 1, coat the frosted silver paste at a speed of 50m / min, and the dry coating amount of the frosted silver paste is 12g / m 2 , and then dried and solidified at 90° C. to form a frosted silver layer 3 . The three-layer structure formed in step 2 is called a frosted silver transfer film. The frosted silver paste is made of non-lea...

Embodiment 3

[0045] In Example 3, white cardboard with a yellow core is used as the base paper layer.

[0046] Step 1: first use a BOPET film with a thickness of 16 μm, and coat a transparent acrylic paint on a coating machine at a speed of 120m / min, with a dry weight of 1.4g / m 2. The acrylic paint layer 4 is obtained after the acrylic paint is dried and cured at 150° C., and the acrylic paint layer 4 and the BOPET film are collectively referred to as a coating film.

[0047] Step 2, on the coated surface of the coating film obtained in step 1, coat the frosted silver paste at a speed of 60m / min, and the dry coating amount of the frosted silver paste is 15g / m 2 , and then dried and solidified at 120° C. to form a frosted silver layer 3 . The three-layer structure formed in step 2 is called a frosted silver transfer film. The frosted silver paste is composed of non-leafing aluminum powder with a particle size of 50 μm and a binder for ink; the weight of the aluminum powder accounts for 14...

Abstract

The invention provides matte silver foil. The matte silver foil is characterized by comprising a base paper layer, an adhesive layer coated on the base paper surface, a matte silver layer coated on the adhesive layer and a surface coating coated on the matte silver layer. The matte silver foil has the advantages that the adhesive layer is provided and coated with the matte silver layer, and accordingly, matte silver paste does not contact with the paper directly, and deformation of the paper can be avoided during drying; additionally, a BOPET (bi-axially oriented polyester film) used during production can be used repeatedly, so that a production process is more environment friendly.

Description

technical field [0001] The invention relates to a frosted silver cardboard, and also relates to a method for manufacturing the frosted silver cardboard, which belongs to the field of packaging materials. Background technique [0002] Commodity packaging is paying more and more attention to aesthetics. At the same time, in order to obtain better anti-counterfeiting effects, merchants also consider using relatively high-end paper when selecting printing base paper, such as aluminum-sprayed transfer paper and colored fiber paper. In order to obtain a metallic texture on the paper packaging box, you can usually use aluminum-sprayed transfer paper or use metallic ink during printing. The metallic texture of aluminum-sprayed transfer paper is almost mirror effect, and the metallic texture of metallic ink is not strong enough in some occasions. . In order to make the wrapping paper have a relatively strong metallic effect, and its metallic effect has no mirror effect, the matte ef...
