Abstract
A reinforced shrink wrap has been developed for use in all types of environments and products or applications. The shrink wrap is tear resistant and can be prepared to withstand exposure from the sun and corrosive elements. The wrap is multilayered with reinforcing filamentous grids in adhesive layers on either side of a shrink film with outer layers of olefin film.
