Abstract

1,003,203. Thermoplastic bags. TRANSATLANTIC PLASTICS Ltd., HANS C. TEPPER, and H. B. DANIELS. June 19, 1964 [March 21, 1963], No. 11236/63. Heading-B8K. [Also in Division B5] A method for making bags from thermoplastic flattened tubular sheet material comprises folding over one of the open ends of the tube, nipping the folded portion so as to leave exposed an area adjacent the fold line and heating this area so as to close the tube by fusion. The bag, which may have pleated sides, has a heat seal 40 along its end adjacent the fold line. A device for making such bags is described (see Division B5).
