ABSTRACT:
Thermoplastic film bags or like packaging sections with or without hanger holes are stacked and welded into pads from which individual bags are easily hand-torn for use. Bag sections, each with a hanger portion and having an arched cut in one wall, are produced three at a time from a continuously longitudinally sub-divided and side seam welded, wide flattened film tube stock web, after incising the cuts at three transversely spaced places in one layer; the sections are stacked and at the hanger parts welded into a pad, and the pad is transversely perforated through the incised arched cuts and hanger holes punched in the hanger part.
