& have spent   BOPP film and tactility is called 'shooting film, matte film, a special surface tactility velvet, cortex matte film. With similar velvet texture of peach skin comfortable strongly, is an ideal choice, you seek different touch with strong ability, wear-resistant and scratch-resistant surface soft delicate and dumb low luminosity.

BOPP touch membrane when using the two main aspects, that is a fold, the second is, the phenomenon of the bubble, in order to prevent undesirable phenomena, we need to pay attention to when using the details below.  


  A, BOPP film and tactility EVA ( Colloid for hot melt glue) , in use is associated with draping quality of colloid heat melt, flow ping. The key to grasp well in the operating temperature, pressure, speed of three key parameters, the rule is: in the guarantee colloid under the premise of fully melting on the surface and the production speed when the temperature and pressure to increase relatively.  


  2, the amount of ink in print, different versions of completely different, the same version also has certain change, and touch the membrane of colloid quantitative is fixed, as a result of ink in printing when most of the mixture is the solvent, the solvent most of colloid and base membrane has a role in melt up, so the print in the effect of the solvent residue control is important to the whole effect of the quality control is a link.  


  Three, many use of solvent-based glue labeling ( The coating) Manufacturers often appear after draping products binding foaming phenomenon, some even though no blisters but can not bend stamping, the reason and the use of coated technology and colloid is directly related to print before they can have a certain effect of solvent residue, and the type of coated coating the glue is not completely volatile solvent after baked road, residual amount is larger, so the draping within products after double solvent is more, from the adhesive solid content analysis, the type of coated coating the solid content of only 5 - per square metre 7 grams, but more difficult to control, and touch the membrane of colloid content in more than 10 grams per square meter, which is why solvent the coating effect of the causes of blister products more easily.
