Problems solved by technology

[0002] At present, the tipping paper for cigarettes on the market is first printed and then hot-stamped on a small area with anodized aluminum, and mainly the text is hot-stamped. Due to the ultra-thin characteristics of the base paper, the hot-stamped tipping paper brings technical difficulties to the implementation of the direct plating process.
At the same time, the anodized aluminum bronzing coating is currently a solvent-based coating, and its toxic and side effects are relatively large. Because the tipping paper is in direct contact with the smoker's lips, it is not good for human health.

example 1

[0018] Example 1: First, on the biaxially oriented polypropylene film (BOPP) molded with a holographic laser pattern, apply a water-based coating—a phenylacrylic acid emulsion, with a solid content of 35%-55% and a mixture of water-based thickener LD-60; The ratio is 98:2. After fully stirring, let it stand for more than 12 hours; the wet coating amount reaches 8-10 grams per square meter during coating; then stick it with raw water pine paper, and squeeze it through extrusion rollers. The light enters the oven, and the temperature of the oven is controlled in the oven so as to control the moisture content of the tipping paper at 5%-8%. Aluminum plating in the aluminum machine, the winding chamber of the vacuum aluminum plating machine must have a cryogenic trap to remove water vapor, and the vacuum degree of the winding chamber should be kept at 5×10 -2 Below MPa, the vacuum degree in the evaporation chamber should be 6×10 -4 Below MPa, at the same time, the temperature of t...

example 2

[0019] Example 2: Firstly, water-based paint——phenylacrylic acid emulsion is coated on the original tipple paper, with a solid content of 35%-55%; the wet coating amount reaches 8-10 g / square meter during coating; Laser-patterned biaxially oriented polypropylene film (BOPP) is laminated, squeezed and calendered by extrusion rollers and enters the oven, and the temperature of the oven is controlled in the oven so as to control the moisture content of the tipping paper at 5%-8%. Remove the biaxially oriented polypropylene film (BOPP), and then put the treated tipping paper into the vacuum aluminum coating machine for aluminum coating. The vacuum degree should be kept at 5×10 -2 Below MPa, the vacuum degree in the evaporation chamber should be 6×10 -4 Below MPa, at the same time, the temperature of the coating drum is set at -10-2°C, and aluminum plating starts after these conditions are completed. Laser direct coated tipping paper can be obtained after aluminum plating is comp...

Abstract

The invention discloses radium irradiating direct plating Chinese water pine paper manufacturing method. It includes the following steps: mixing cinnamic acid latex with hydrophilic thickening agent in weight percentage of 97%-99% and 1%-3%, standing more then 12 hours to form hydrophilic paint; coating hydrophilic paint on BOPP film with 8-10g / sq m wet coating weight; jointing the base paper with the coating surface; mill finish; drying to make the water content be 5%-8%; peeling off the BOPP film; aluminum plating in vacuum to obtain the finished product. The invention has the advantages of simple, reasonable, scientific select material, good for increasing cigarette grade, reducing its influence for people's health.

Description

technical field [0001] The invention relates to tipping paper for cigarettes, in particular to a method for manufacturing tipping paper directly coated with laser. Background technique [0002] At present, the tipping paper for cigarettes on the market is first printed and then hot-stamped on a small area with anodized aluminum, and mainly the text is hot-stamped. Due to the ultra-thin characteristics of the base paper, the hot-stamped tipping paper brings technical difficulties to the implementation of the direct plating process. . At the same time, the anodized aluminum bronzing coating is currently a solvent-based coating, and its toxic and side effects are relatively large. Because the tipping paper is in direct contact with the smoker's lips, it is unfavorable to human health. Therefore, researching and developing a kind of tipping paper without toxic and side effects is the voice of cigarette enterprises and the majority of smokers, and has important practical signifi...
