Abstract
A heat shrinkable wrap-around sleeve comprises a heat shrinkable sheet with a heat stable strip welded on one end. The free end of the heat stable strip is overlapped on the outer side of the opposite end of the sheet and welded thereto by heating applied directly on the outer side. This allows the material of the strip to differ in its properties from the material of the sheet, so that the nature of welded closure can be tailored to particular applications. It also allows manufacture of sleeves having hold-down adhesives applied on them to be conducted with greater ease and economy. The sleeve can be manufactured using continuous welding, for example by heated wedge welding.
