Production method of embossing form packing paper

Abstract

An embossing type tipping paper production method relates to the packaging material technical field. The invention comprises the following procedures that: a. coating: PET plastic light film is adopted as base material; a layer of macromolecule resin material is uniformly coated on the base material in advance; after drying and solidification, a layer of transparent surface coat with strippable performance is formed; b. mould pressing: after the coating, under the conditions of the pressure of 2Kg / cm<2> to 4Kg / cm<2>, the temperature of 160 to 180 DEG C and the speed of 35 to 45 m / min, characters or patterns on a mould pressing plate are transferred on the transparent surface coat of the PET plastic light film; a printing layer stuck on the transparent surface coat is produced to form a surface layer; c. aluminium plating; d. transferring; e. embossing: aluminum transferring paper achieved by the procedures is sleeved between a reverse rotating knaggy patterned roller and an elastic roller which are tangential. The invention has good anti-fake effect and suboptical effect and is easy to mass production.

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, the surface of the vacuum aluminized transfer paper packaging material produced by the above-mentioned process is very smooth, especially the cigarette holder wrapping paper produced by the above-mentioned transfer paper is easy to slip from the mouth during use, which brings inconvenience to the user.

In addition, the smooth surface produces total reflection, but the local luminous effect is the best. In order to have a matte effect and produce diffuse reflection, matting powder is generally added to the ink during the printing process, but the packaging material produced by this method is sub-light The light effect is not uniform, and it is not easy to grasp the proportion of the added matting powder, which increases the production cost. At present, when producing tipping paper with a matte effect, 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 and is not easy to identify, which is not convenient for mass production
