Lines superimposing type packing paper and producing method thereof

Abstract

The invention relates to lineation overlapped-typed tipping paper and a production method thereof, and relates to the packing material technical field, in particular to an environmental protection-typed metallization packing material with a printing pattern. The invention comprises a bottom layer, a binding layer, an aluminum coating and a surface layer which are mutually compounded, wherein, the surface layer is composed of a surface coating and a printing layer, and also comprises at least a layer of color line layer, wherein, the color line layer is bond with the surface layer. The invention comprises the following steps: a. coating; b. molding: the surface of PET plastic optical film basis material of the transparent surface coating is provided after being coated, the transparent surface coating changes micro-deformation through extruding a molding printing plate with a character and a pattern under the pressure of 2 Kg / cm <2> to 4 Kg / cm<2>, the temperature of160 to 180 DEG C, the speed of and 35 to 45m / min, the character and the pattern on the molding printing plate is transferred on the transparent surface coating, thereby generating a printing layer covered on the transparent surface coating, and forming the surface layer; c. aluminum coat; d. transferring. The invention aims at having good anti-counterfeit effect, being easy to be produced, and having good visual effect.

Description

technical field [0001] The invention relates to the technical field of packaging materials, in particular to an environment-friendly metallized packaging material with printed patterns. Background technique [0002] Vacuum aluminum transfer technology is used to produce packaging materials and other types of paper, that is, aluminum with a purity of 99.9% is heated to 1400-1500°C to evaporate it, and then it is coated on the carrier by condensation and then transferred to the paper to make the paper An ultra-thin aluminum film is formed on the surface. The thickness of the aluminum layer through vacuum aluminum plating is 0.02μm-0.04μm, which is only 1 / 200 to 1 / 300 of the thickness of the aluminum foil. This kind of vacuum aluminum-coated transfer paper has a strong metallic luster in appearance, and is widely used in wine, cosmetics, supplements, food, medicines, especially the packaging of cigarette inner linings and shells, which consumes less material and waste less , ...

Problems solved by technology

[0003] However, to print text and patterns on vacuum aluminum-coated transfer paper packaging materials, the production process of laminating and peeling first and then printing is generally used at present. For products that require pattern or text printing on packaging materials, the above process has the defects of time-consuming, laborious and high cost. Not easy to mass produce

In addition, the tipping paper currently produced only prints ordinary text on the packaging material, and the pressure is controlled at 2Kg / cm 2 , the temperature is 160°C, the speed is controlled at 45m / min, and 39g / m is selected 2 The transfer paper obtained in this way has no obvious laser effect, is not easy to identify, is easy to be imitated by others, and has a single visual effect
