Paper honeycomb cushioning pad

In a double faced expanded paper honeycomb cushioning pad adapted for preventing blowouts through the ends of said double faced expanded paper honeycomb cushioning pad upon impact, said double faced expanded paper honeycomb cushioning pad comprising a plurality of sheets of Kraft paper adhered together along parallel spaced apart glue lines, expanded to form air cells hexagonally shaped in cross section and bounded by portions of said sheets of Kraft paper, and double faced by facing sheets of Kraft paper adhered over the top and bottom of the expanded paper honeycomb cushioning pad, thereby forming in said double faced expanded paper honeycomb cushioning pad a plurality of adjacent closed air cells hexagonally shaped in cross section, said double faced expanded paper honeycomb cushioning pad having a pair of ends each comprising a row of vertically sliced air cells, the glue lines of said vertically sliced air cells being normal to said ends, the improvement which comprises means for preventing blowouts through said ends of said double faced expanded paper honeycomb cushioning pad, said blowout preventing means comprising two end caps, each of said two end caps being adhered to the exterior surfaces of said double faced expanded paper honeycomb cushioning pad adjacent to one of said two ends so as to close and seal each of said two ends, said end caps being constructed of 70 to 80 lb. Kraft paper tape, said Kraft paper tape being folded over said facing sheets and over the side surfaces of said double faced expanded paper honeycomb cushioning pad to a sufficient extent and adhered sufficiently tightly to said facing sheets and said side surfaces to prevent a blowout from occurring through either of said two ends of said double faced expanded paper honeycomb cushioning pad upon impact.
