Problems solved by technology

The vacuum aluminized paper made by this process method has the following disadvantages: because the nitrocellulose coating on the surface of the aluminized paper becomes rough when the polyester film is peeled off, the surface finish of the aluminized paper is poor and lacks luster; The process makes it difficult to control the color difference of the product; due to the poor ability of nitrocellulose to resist organic solvents, the surface printing adaptability of the aluminum-coated paper made is poor, and large-area printing cannot be carried out

Embodiment 1

[0025] The nitrocellulose was dissolved in a mixed solvent of cyclohexanone, butanone and ethyl acetate to form a nitrocellulose solution with a solid content of 8% by weight.

[0026] According to the weight ratio, 12 parts of polymethyl methacrylate, 3 parts of amino resin, 0.6 part of polydioctyl terephthalate and 1 part of leveling agent were dissolved in 83.4 parts of cyclohexanone to form an acrylic resin solution.

[0027] The nitrocellulose solution and the acrylic resin solution are uniformly mixed at a weight ratio of 1.5:1 to form a release agent.

[0028] Cover the above-mentioned release agent on the polyester film on a gravure printing machine, and then dry it in an oven to form an easy-release coating, and the temperature of the oven is 90-140°C. Repeat the operation to form an easy-peelable coating with a thickness of 1.0-1.8 grams per square meter.

[0029] On the vacuum coating machine, the metal aluminum is heated and melted and then sprayed onto the easy-p...

Embodiment 2

[0035] The nitrocellulose was dissolved in a mixed solvent of ethyl acetate, butyl acetate and cyclohexanone to form a nitrocellulose solution with a solid content of 8% by weight.

[0036] Dissolve 14 parts of polymethyl acrylate, 3 parts of amino resin, 1 part of polydioctyl terephthalate, and 1 part of leveling agent in 81 parts of cyclohexanone to form an acrylic resin solution.

[0037] The above-mentioned nitrocellulose solution and acrylic resin solution are uniformly mixed at a weight ratio of 2.3:1 to form an easy-peelable coating.

[0038] Coat the above release agent on the polyester film on a gravure printing machine, and then dry it in an oven to form an easy-peelable coating. The temperature of the oven is 90-140°C, and the thickness of the formed easy-peelable coating is 0.5-0.7 gram.

[0039] The acrylic resin solution is coated on the surface of the above-mentioned easy-peelable coating on a gravure printing machine, and dried in an oven at 90-140° C. to form...

Abstract

In the present invention, polyester film is painted with easy-to-peel coating, sprayed with aluminium and adhered with paper layer, and the polyester film is then peeled and paint containing pigment is painted to the easy-to-peel coating to obtain the product. The easy-to-peel coating consists of nitro cellulose and acrylic resin. The improved easy-to-peel coating has raised organic solvent resistance, can be colored in great area, and is covered with rougher easy-to-peel layer and thus has high smoothness and mirror effect. The aluminum-plating paper can be printed and colored in controlled color difference.

Description

technical field [0001] The invention relates to a method for manufacturing a vacuum aluminized paper composite material and its product, more specifically, to a method for manufacturing a vacuum aluminized paper packaging material coated with a color layer on the aluminized film and its product. Background technique [0002] Vacuum aluminized paper is a packaging material used in the packaging industry in recent years. It has a good metallic texture and is suitable for processing on embossing machines and high-speed cross-cutting machines. It has the advantages of avoiding light, moisture, and degradability. It can replace Aluminized plastic films and pure aluminum thin composite materials have broad prospects due to their low aluminum consumption, and have been widely used in the packaging and decoration of cigarettes, food, medicine, and trademarks. At present, the vacuum aluminized paper with coloring effect all adopts the pre-coloring method. The process method is to coa...
