Problems solved by technology

However, the production and use of oil-based paints are harmful to the environment and the human body, and do not meet the requirements of environmental protection. The process of producing inner lining paper by transfer method is complicated and difficult to control
The aluminum foil composite process is relatively simple, but the thickness of the aluminum foil is generally 6-7 microns, while the thickness of the aluminum layer in the transfer film is only 300-400 angstroms, and the thickness of the aluminum foil is about 200 times the aluminum thickness of the transfer film. From the perspective of energy saving, aluminum foil Composite is no longer used

Embodiment Construction

[0006] Embodiment: During production, because the process has few steps and relatively low requirements on adaptability and friction resistance, the water-based paint is selected as the top coat. Water-based coatings can use polyurethane, acrylic, and cellulose-based water-based coatings. While topcoating, control the moisture content of the cardboard at 2.5%-3.2%. The laser molding process can be completed by using the existing soft pressing method. The base paper is molded with holograms and texts through a high-temperature nickel plate at 180°C, and the information on the nickel plate is transferred to the base paper. The rubber roller for pressing is required to be non-deformed and uniform in hardness, generally 80-90 degrees, with good temperature resistance and a smooth surface. High finish.

[0007] The aluminum plating process utilizes the existing vacuum drum aluminum plating method. Under vacuum conditions, the aluminum is heated and melted first, so that the alumi...

Abstract

A method for manufacturing a direct plating lined laser paper of cigarettes is disclosed, which main technological process comprises the steps of coating the base paper surface with a coating layer, laser molding the base paper after the coating, then aluminum plating the base paper, and then brushing and coating a layer to obtain said direct plating lined laser paper of cigarettes. The present invention simplifies the technological process by taking out adhesive and thin film in a metastasis process, and then saves the using amount of metal aluminum in contrast to aluminum foil compound, and lowers the energy consumption and manufacturing cost; furthermore, eliminates the potential harm of residual additive of the original paint to environment and human, by utilizing waterborne coatings.

Description

technical field [0001] The invention relates to a method for producing cigarette lining paper, in particular to a method for producing cigarette lining paper by direct plating, and belongs to the technical field of aluminized paper production. technical background [0002] At present, transfer paper and aluminum foil composite paper are mainly used for cigarette lining paper. The technological process of lining transfer paper is mainly: film coating-aluminum plating-composite-peeling-top coating. In production, the process is still relatively complicated, and the loss is relatively large. The transfer method is used to coat a layer of bonding material with a hot-melt resin on the film, such as PET and BOPP, and then carry out aluminum plating under the condition of a vacuum of 0.008-0.08 Pa, and then use the adhesive to bond the base paper and the aluminum-plated film. After compounding, after a period of curing, the film substrate is dealuminated and peeled off, and the al...
