Problems solved by technology

However, there are still the following problems: first, the transfer coating not only requires better peelability between the coating and the base film PET film after film formation, but also needs to be matched in the subsequent printing process; second, the manufacturing cost is relatively high. Special requirements, the range of available materials is small, for example, the use of more acrylic water-based emulsion is not suitable for the preparation of water-based transfer coatings
At present, only polyurethane emulsion is more suitable, but the cost of this material is more than 20% higher than that of solvent-based transfer coatings, which is difficult for relevant enterprises in the industry to bear

Abstract

The invention belongs to the technical field of cigarette matching materials and relates to packaging card paper for cigarettes, in particular to a production process for water-based transfer card paper. The production process comprises the following steps: firstly, carrying out corona treatment on a PET basement membrane; secondly, coating the corona surface of the PET membrane with a pretreating agent by a screen roller; coating the surface on which the pretreating agent is coated, of the PET membrane with a water-based transfer coating by using the screen roller; carrying out vacuum aluminum plating on a dried water-based transfer membrane, coating the surface of an aluminum layer with compound glue, compounding the water-based transfer membrane with ordinary card paper, and the stripping off the PET membrane; slitting, grading, packaging and warehousing to obtain the water-based transfer card paper. The pretreated PET membrane has good strippability, so the influence of the strippability when the water-based transfer coating is selected can be neglected, and the material selecting range is widened. According to the production process disclosed by the invention, the limitation that the performance of the water-based transfer coating is only improved when the water-based transfer card paper is researched in prior art is broken, and the problem about performance and cost which exist in the industry and are difficult to solve are solved.

Description

technical field [0001] The invention belongs to the technical field of cigarette supporting materials, relates to cigarette packaging paper, in particular to a production process of water-based transfer paper. Background technique [0002] At present, in the cigarette industry, compared with the composite cardboard used earlier, the transfer cardboard used in large quantities not only saves resources and reduces costs, but also has a better environmental protection effect due to the reduction of the use of a layer of plastic film that is difficult to degrade. Big improvement. However, the environmental protection problem of this type of product still exists, and the main reason is that the transfer coatings used are all solvent-based, and a large amount of organic solvents will be used and discharged during the production process, causing environmental pollution. According to incomplete statistics, the current cigarette accessories industry uses about 20,000 tons of transfe...
