Abstract

An improved shrinkable covering made of a shrinkable plastic compound having an inlay of non-recoverable threads and recoverable threads has the recoverable threads arranged with excess length, preferably in helical form, and extending in the stretching and shrinking direction of the covering. As a consequence of this excess length, the recoverable threads are not subjected to any additional stretching during the stretching process of the covering. The recoverable threads act as 'swelling agents' in the shrinking process and seal off any longitudinal capillary cavities which may be produced during the production process of the shrinkable covering.
