Abstract

Bags incorporating an adhesive strip for sealing the bag after loading are made from continuous lengths, of superimposed or folded sheet by applying an adhesive tape along one edge of a projecting border of the sheet, and then securing an ancillary strip of another sheet along the opposite edge of the adhesive tape, leaving the central third of the adhesive tape exposed. The extra strip is perforated and folded parallel to the tape to cover the central zone of the tape, to prevent anchorage of the adhesive tape while the sheets are transversely welded and cut to produce individual bags. Allows continuous automated conversion of sheet to bags with an adhesive seal, esp. for mfr. of bags from polypropylene sheet ofr film. When ready for use, the ancillary strip is peeled off to expose the adhesive border for sealing the flap of the main bag.
