Abstract: A polyethylene or polypropylene bag is provided with a two-section flap. The sections are spaced by a gap, but are connected by Scotch tape which bridges the gap. Part of the adhesive on the tape is exposed through the gap and provides an adhesive strip for the sealing, opening and resealing of the flap. The bag is provided with an ink-receptive characteristic, except in correspondence with the adhesive strip, to assure retention of the adhesive on the tape. The bag can be provided with a mouth closed by the flap and with the opposite end open so that goods can be inserted through the open end and later accessed via the mouth when the flap is opened.

Abstract: Apparatus and methods are provided for manufacturing plastic film bags with two-piece flaps. A slitting tool slits the flap portion of a longitudinally displaced film strip arrangement and a spacing tool displaces one of the resulting sections to form a gap. Thereafter, an adhesive hearing tape is applied to bridge the gap and connect the separated sections. After this, a cutting tool cuts notches into the two-piece flap portion which is lifted for this purpose by a Teflon-coated template having a slot to receive the cutting tool. The template has a channel system to enable blowing away the cut out portion. The separate bags are formed by sealing and severing at a position to intersect the notches. The method of the invention involves cutting the notches into the flap section to delineate separate flaps and associated bags in a time frame which follows the folding of the flap section over the main body of the bag.
