Description

A kind of flexo picture and text cigarette paper and preparation method thereof
Technical field
The invention belongs to cigarette paper technical field, in particular to a kind of flexo picture and text cigarette paper and preparation method thereof.
Background technique
Auxiliary material of the cigarette paper as cigarette carries volume although its weight only accounts for the 5% of whole branch cigarette weight It is one of essential raw material in the cigarette appearance and cigarette making process of 70% or more cigarette, occupies in tobacco industry More important status.
With the continuous development of cigarette market, consumer to the cigarette appearance of common horizontal, vertical rib-loop form increasingly It is unsatisfactory for, therefore designs novel appearance, have distinctive cigarette paper, can not only attract consumer, enterprise, company can also be carried Industry image and culture, while antiforge function can be had both.Therefore particular appearance cigarette paper is increasingly taken seriously in cigarette industry.
The preparation method of the particular appearance cigarette paper used now is being applied as granted patent ZL200910094465.7 is used Glue workshop section addition prepared opium paste carries out the method dyed to cigarette paper.This method can be prepared into colorized cigarette paper, but use this side Method can not prepare the cigarette paper for having picture and text.
For another example granted patent ZL201310142147.X is used in the marking roll with trellis, in papermaking press portion to cigarette paper The method for carrying out coining trellis picture and text, preparation method may only be applied to the preparation of trellis line cigarette paper, and pattern is simple, and its Processing method is imprinted in squeezing section, is influenced by paper machine dryer pulling force, and pattern can generate a degree of deformation, is used The method of this squeezing section coining, can only prepare the simple cigarette paper of pattern.
For another example 201610668088.3 are applied for a patent using the method imprinted again after cigarette paper forming to realize preparation A kind of cigarette paper with imprinted pattern text, this method cooperate ebonite roller, wool felt using the steel rider with convex pattern, ebonite roller etc. Roller applies pressure to upper and lower two kinds of roll bodies, on convex imprint patterns to cigarette paper, the coining picture and text that are prepared using this method Although cigarette paper clear patterns, air permeance for cigarette paper decline, the air permeability coefficient of variation is increased, and longitudinal tensile energy reduces, Reduce cigarette paper service performance.
Realize that cigarette paper has rich colors, fine pattern under conditions of guaranteeing cigarette paper service performance currently, there is no Report.
Summary of the invention
In view of this, the purpose of the present invention is to provide a kind of preparation methods of flexo picture and text cigarette paper.The present invention provides Preparation method ensure that cigarette paper service performance, and obtained flexo picture and text cigarette paper rich in color, that picture and text are fine.
In order to realize the purpose of foregoing invention, the present invention the following technical schemes are provided:
The present invention provides a kind of preparation methods of flexo picture and text cigarette paper, comprising the following steps:
