High final shrinkage

Like Styrolux HS 70, Styrolux T/S films are particularly well-suited for the technology of transverse stretching (transverse direction or TD). TD films allow shapes having widely varying radii or unusual designs to be shrink-labeled by sleeve technology.

The new product formulation has succeeded in retaining the well-balanced shrinkage curve of Styrolux HS 70, along with a very high final shrinkage of more than 70 percent at 90°C [194°F]. The uniform, moderate rise of the shrinkage curve permits well-controlled shrink-labeling over a very broad processing range, whereas the high final shrinkage makes it possible to decorate even the most complex of shapes.
