Abstract
Description
Technical Field

[0002] With the rapid development of solvent-free composite adhesives, processes and equipment, the application fields of solvent-free compounding are becoming wider and wider.
[0003] Cigarette packaging boxes are mainly used to protect cigarette sticks and facilitate the storage and transportation of cigarettes. Currently, the papers used for making cigarette packaging boxes are mainly white cardboard for hard packs and coated paper for soft packs. These papers belong to high-grade packaging papers. In order to increase the decoration and anti-counterfeiting properties of cigarette packaging boxes, transfer cardboard obtained by laminating white cardboard or coated paper with a transfer film and then peeling off the base film is usually used as the material for making the box body.
[0004] Traditional coating compounding machines can only meet the requirement of coating and gluing one side of the paper before compounding. If both sides of the paper need to be coated, after coating and gluing one side of the paper, the paper needs to be unwound again and the other side needs to be coated and glued. This form is rather cumbersome and inconvenient.
