Composite transferring technique for card paper for cigarettes

Abstract

The invention belongs to the technical field of packing paper for cigarettes and relates to a production technique of card paper for cigarettes, in particular to a composite transferring technique forcard paper for cigarettes. Firstly, an ordinary full-plate aluminum-plated transferring film is locally coated with an oil protecting agent through an intaglio printing mode, the aluminum-plated transferring film coated with the oil protecting agent is coated with a solid glue layer through a three-roller squeezing mode, and liquid coating is conducted through a heating melting mode; and finallythe aluminum-plated transferring film and the card paper for the cigarettes are subjected to composite stripping. Under the effect of laminating pressure, the aluminum-plated film coated with the gluelayer and the card paper for the cigarettes are composited, the portion, coated with the oil protecting agent, of the glue layer is separated from an oil protecting layer, and after stripping, the aluminum-plated transferring card paper with an information layer is obtained. According to the production technique, through the oil protecting agent coating mode, presenting of different patterns andwords is achieved, the effect is exquisite, and a traditional aluminum-washing technique is substituted; no solvent is volatilized in the adhesive laminating process, high-temperature drying is not needed, the surface of the manufactured card paper for the cigarettes is exquisite in pattern and attractive in effect and meets the environment-friendly packing requirement.

Description

technical field [0001] The invention belongs to the technical field of cigarette wrapping paper, relates to a production process of cigarette cardboard, in particular to a composite transfer process of cigarette cardboard. Background technique [0002] Traditional cigarette cardboard can be divided into three categories according to different production processes: white card printing cardboard, transfer printing cardboard and composite printing cardboard. The white cardboard printing process is made by using ordinary cardboard base paper to print (or coat) with ink (or paint), and then perform subsequent processing such as slitting and embossing; the transfer printing cardboard process uses PET or BOPP The transfer film is coated with the transfer coating, which is compounded with the base paper after vacuum aluminum plating, peeled off the coating (or printing) coating (or coating), and finally processed by cutting, embossing, etc.; the composite printing cardboard is made ...

AI Technical Summary

Problems solved by technology

There are corresponding defects in these three types of paperboard for cigarettes. For example, the decorative effect of white paperboard printing paperboard is average; the decoration effect of transfer printing paperboard and composite printing paperboard is improved, but the production process of the former is complicated, while the latter consumes more resources.
