Foil For Tobacco And Ink Encounter To Create A Unique Art Aug 25, 2017

Foil for Tobacco and ink encounter to create a unique art
 Foil for Tobaccos are composite materials of aluminum and paper. When the operating or the use of environmental temperature and humidity changes so that it is too late to reach the internal balance, the double layer structure connected by the inner coating or the adhesive will produce internal stress, which will not only cause expansion or contraction , And because of changes in moisture content, but also make the paper local size changes, the formation of curl, wrinkles, waves or even permanent deformation, seriously affecting the printing and post-processing quality. Therefore, in order to ensure the normal printing of Foil for Tobacco, we must control the printing and dyeing temperature and humidity, so that the workshop temperature maintained at (25 +2) ℃, relative humidity remained at 50% to 60%.
Printing and dyeing before the temperature and humidity balance and its important, temperature and humidity does not reach the balance will produce static electricity, resulting in difficult feeding. The actual production, the original packaging of Foil for Tobacco in the workshop at least 16h to open the cut white material, 8-12 hours after the printing. In addition, in addition to dry paper drying rack, the printing process in the processing period should also cover the plastic film moisture or reduce the telescopic deformation.
 Foil for Tobacco placed in the air, the surface will immediately generate a layer of very thin layer of dense oxide, if the oxide layer is not dirty, the ink has a good adhesion. But the actual production of Foil for Tobacco by the lubricant and environmental dust pollution, the formation of a layer of thin film affect the adhesion of ink. Therefore, the printing of Foil for Tobacco must be pre-press the erosion of the coating treatment to eliminate the lubricant class of dirt, and enhance the ink and foil surface of the adhesion. The same time as
Foil for Tobacco etchability coating treatment, also known as the bottom surface treatment, is the use of shellac coating or nitrocellulose coating on the surface of the Foil for Tobacco primer coating. After coating, the printing surface is no longer a Foil for Tobacco but a coating material. These coating materials have good affinity with the ink, thereby increasing the adhesion of the ink to the foil surface.
Foil for Tobacco is a very popular packaging materials, not only has excellent thermal conductivity and shading performance, but also moisture, airtight, fresh. Moreover, Foil for Tobacco can also be used for printing. So when the Foil for Tobacco encountered in the printing, how should it be printed on it?
 Foil for Tobacco printing requirements are relatively high, can be offset, gravure, flexographic printing.
      Gravure printing: suitable for printing large quantities of roll material. The surface of the impression cylinder is wrapped with a layer of thick rubber blanket having a certain elasticity so that the ink at the printing plate pocket is smoothly transferred to the surface of the Foil for Tobacco.
 Flexible printing: more advantages than gravure, plate speed, low cost, high efficiency, not only for large quantities of printed copies, the bulk of small, more varieties of printed the same applies to be promoted.
     Offset: Because of its easy plate making, network clear, printing speed.
See the Foil for Tobacco we should think of is the barbecue or cigarettes it, it wrapped in the outer food, so cooked quickly and rich flavor, not easy to cool.
And it has a good finish and heat reflex, with the protection of Foil for Tobacco, the taste of cigarettes will not be subject to external stimuli and taste, more importantly, it will not be humid and humid environment and taste, cigarettes The tobacco will not degenerate, so that their shelf life longer!
Only in this way, it has a lot of small features. But also to do ironing board, in the paper sprinkle some water, with iron ironing plate Qi, stick to the smooth board, it formed a Foil for Tobacco ironing board. Foil for Tobacco has a good finish and hot reaction, in the ironing clothes not only save time and time. Moreover, the pots wrapped with Foil for Tobacco not only prevent long moss, but also anti-borers.
