Problems solved by technology

Moreover, the positioning of this process is very difficult, and the accuracy of accurate positioning of the front, rear, left, and right is required to be about 0.1mm. This positioning accuracy requirement is difficult to achieve stably for the imported printing machines currently used in the industry, and it cannot be truly industrialized.

Embodiment 1

[0028] A production process of partial laser direct coating paper is realized through the following steps:

[0029] (1) The OPP laser base film with a thickness of 22 microns is pre-coated with a layer of direct-plating glue, and laminated with the direct-plating lining base paper with a weight of 52 grams through a squeeze roller. Machine speed 100m / min, temperature 110℃, coating weight 2.1g / m 2 , the OPP laser base film and direct-plating base paper used are commercially available, and the direct-plating glue used is WD-1001F direct-plating paint, purchased from Shanghai Weikai Chemical Co., Ltd.;

[0030] (2) The semi-finished direct-coated paper after drying peels off the laser base film, the machine speed is 120m / min, and the temperature is 60°C. Maintaining a certain temperature during the peeling process is to further reduce the moisture content of the direct-coated paper, so that the subsequent aluminum-plating stage The vacuum degree in the vacuum chamber can be more...

Abstract

Belonging to the field of cigarette supporting materials, the invention relates to a cigarette direct plating lining paper, in particular to a local laser direct plating paper production process. The local laser direct plating paper production process provided by the invention includes: firstly conducting transfer direct plating on direct plating raw paper by a laser transfer base film, carrying out drying and stripping, locally applying fluorocarbon oil in an aluminum plating machine large vacuum chamber, then performing aluminum plating, and finally applying a waterborne top paint to the surface. For the local laser direct plating paper obtained by the production process disclosed in the invention, due to the instantaneous volatilization characteristic of fluorocarbon oil, the surface of the direct plating paper coated with fluorocarbon oil in the vacuum chamber has no aluminum layer, when the surface is coated with the waterborne top paint, the top paint and a direct plating glue are mutual soluble, thus having no laser effect, and realizing fine local laser. The prepared direct plating paper has very fine local laser effect, and the laser edge has a clear boundary, thus overcoming the defect that due to the incapability of aluminum washing of direct plating paper, the laser direct plating paper obtained by local mould pressing has poor effect.

Description

technical field [0001] The invention belongs to the field of supporting materials for cigarettes, and relates to direct-plating lining paper for cigarettes, in particular to a production process for local laser direct-plating paper. Background technique [0002] In the traditional sense, the direct-plating lining paper refers to the direct-plating coating layer coated on the direct-plating lining base paper, which is dried and aluminized. Evaporation boats are commonly used for aluminizing, and the resistance is heated to 1350-1500 in a vacuum. ℃, aluminum atoms evaporate to the surface of the substrate. The outstanding feature of vacuum direct plating lining paper is better environmental friendliness, without using transfer film. The thickness of the aluminum layer of the vacuum direct-plating lining paper is only 0.020-0.040 μm, and the aluminum consumption is only about 1 / 200 of that of the composite aluminum foil paper, which greatly reduces the consumption of metal alu...
