Abstract
A preformed bag-like enclosure formed of heat shrink plastic film for shrink wrapping pallet loads or the like, the enclosure being generally tubular or sleeve-like in shape and provided with a reduced size opening at the top to prevent the enclosure from slipping down over the load to be wrapped prior to the application of heat for shrinking. In one embodiment the top opening is reduced in size by tapering same using upwardly and inwardly extending heat seals, in another by providing transversely extending heat seals and in further ones by providing inwardly spaced spot welds. Methods of fabrication of the latter type are also disclosed.
