Transparent label has three layers, namely printed layer, adhesive layer and the backing sheet. Beer material BOPP is often used because it has a certain degree of stiffness for high-speed labeling.

BOPP good printability, letterpress, gravure, flexo, screen printing, and so on, and can also be used for gold and silver. Glue can be emulsified base can also be water-based. But if after labeling the bottle in the filling into the sterilizer, emulsion-based adhesive with heat turns white, undermined the transparency effect. Of course, no matter which kind of gluing must be chilled and soaked in water to maintain transparent and sticky relay. End of paper usually PET or PP film, PET 30 μ m thick PP film is better than the corresponding fixed wheel on the label.

In order to achieve the best effect of labeling, labels and bottles cannot be more than o.3mm and concave, or bubbles and wrinkles. Labeling bottles shall be dry, dust-free of dirt, temperature not less than 18 ° c equipment in addition to the static is much better.

Transparent label technology face the problem now is to work with the beverage production speed. Because current paper labels the label speed up to 60,000 per hour can be aligned with the production speed, clear labeling of the pressure-sensitive label also needs to achieve the same speed. Looking for speed the solution at the same time, the clear pressure sensitive new materials but also brought a lot of printing and processing technology, these are from traditional paper labels to transparent labels beer labels must be considered before.
