Abstract
A strip of adhesive tape is relatively permanently attached at one end to a bag near the open end thereof and is strippably attached to the bag in the remaining portions of the tape. To close the bag, the strippable portion of the tape is stripped away from the bag, which is then puckered and desirably twisted near the tape. The free end of the tape is then looped around the puckered end of the bag and is fastened by its adhesive to the puckered portion of the bag and/or to the anchored end of the tape, thus to close the bag.
