ABSTRACT:
Disclosed is a wraparound protective closure in sheet form having a specially profiled transverse-edge which is enveloped when the closure is overlappingly wrapped around an elongate substrate and a method of protecting an elongate substrate using said closure. Repeating structural units along the profiled transverse-edge comprise spoiler-edges which run at right angles to the transverse direction of the profiled transverse-edge and cause air trapped along the enveloped, profiled transverse-edge to form into discrete pockets away from the spoiler-edges when the closure is overlappingly wrapped around the elongate substrate instead of forming a continuous channel along the enveloped edge. The wraparound closure is preferably a dimensionally-recoverable wraparound closure, most preferably a heat-shrinkable wraparound closure, and especially a closure comprised of a polymeric composition.
