Abstract: A method of wrapping an object with a heat-shrinkable material. A sheet of the heat-shrinkable material is heated to its frosting temperature and then fitted around the object like a sleeve so that leading and trailing ends of the sheet overlap and are welded together. The object and the sleeve are allowed to cool to shrink the sleeve onto the object.

Abstract: A sleeve-type half package is closed by applying two beads of glue on each of two flaps on each end of the sleeve, folding those flaps inwardly by engagement with a nonglued strip between the beads and then folding the other two flaps at each end inwardly to engage a bead of glue on each of the two first-folded flaps at each end. The folding is done by thrust members as the half package is displaced linearly along a transport path.
