Heat-recoverable sheet for use as protective closure |
摘要 |
A heat-recoverable sheet is provided having two opposing exterior transverse edges and interior edges transverse to the direction of recovery of the sheet extending from one of said exterior edges. When the heat-recoverable sheet is coated on one face thereof with a hot-melt adhesive and used as a wrap-around protective closure with the interior edges and the hot-melt adhesive enveloped within the closure, the movement of the enclosed exterior edge during recovery is retarded to minimize the formation of any void spaces in the hot-melt adhesive.
