Novel package wrappers made of humidity resistant plastic, utilizing a teartape disposed proximate to, but spaced inward from, one edge of the package, extending substantially linearly continuously about three adjacent sides. The teartape in one form of the invention is a separate tape adhered to the package wrapper, and in another form of the invention is integral with and formed from the package wrapper itself. The package is completely sealed but does not require the use of any tool to open it. After the teartape has been removed, fingers or a thumb may be inserted beneath the revealed torn edge of the wrapper and the wrapper torn downward through slits in the then exposed portions of the ends of the package wrapper which had been previously overlaid by the teartape ends, such slits being concealingly disposed and sealed beneath the overlying ends of the intact wrapper before removal of the teartape. By locating the teartape fairly closely to one edge of the package and providing the underlying tear down slits in the package wrapper ends, the intact upper corners of the opened package are able to slide smoothly over and down around the corners of the contained product without exerting any substantial pressure thereon, so that no corner curling force is exerted on the sheets sufficient to cause corner distortion. The wrapper is quickly and easily removable from the contents, so that the dry undistorted paper may be quickly loaded into a copy machine.
