MD films

The new Styrolux T/S films not only are suitable for transverse stretching processes but, as so-called MD films, they also yield high-quality products. Stretching films in the extrusion direction (machine direction, or MD) as is done in band labeling technology is simpler from the standpoint of the machinery employed, and thus correspondingly cheaper. With the roll-on-shrink-on (ROSO) method the film label is wrapped around the bottle in the form of a band, fixed by glue, and then shrunk onto the bottle under the effect of heat.
