Abstract

A shrinkable composite section is formed from a shrinkable composite foil composed of at least two shrinkable planar foils adhering firmly to one another. Each of the two shrinkable foils has a shrink direction proceeding at a suitable offset angle relative to the shrink direction of the other individual planar foil so that the resulting overall shrink direction occurring for the composite foil extends between the shrink directions of the two individual foils. The tendency toward tearing or, respectively, continued tearing of the shrinkable composite foil section is, thus, diminished.
