ABSTRACT:
A hot-melt adhesive line and an article of manufacture including the same are made up of one or more bundles of fibrous strands (49% by weight) and hot-melt adhesive to effect interfibrous adhesion after heated dispersion throughout the fibers of the strands. The line has an extruded outer layer of compacted adhesive to enclose the strands of the bundle and to adhere by uniform spreading of the entire strand onto a container surface. Typically, 1000 strands of man-made material are included in a hot-melt adhesive line that is 0.024 inch in diameter. Adjoined, side-by-side strands provide tape one-half inch in width.
