AbstractA method is provided of making a bag including the steps of:Expanding tubular plastic netting in continuous rope form into an elongated sleeve with an open end;Positioning a first bottom closure strip across a first part of such sleeve;Positioning a second bottom closure strip across a second part of such sleeve and aligned with such first strip;At least one of the strips having an adhesive coating on its inner surface and such strips being arranged to extend substantially from one edge of the sleeve to the other edge; and,Adhering the first and second strips together through open meshes of such netting thereby to form a bag having a closed end and an open end.In forming a closure for such a bag the method preferably includes the steps of:Expanding such tubular netting in the cross-machine direction;Gathering such expanded netting in rucked form;Expanding a portion of such rucked netting in the machine direction into an elongated sleeve; andApplying closure members across such sleeve thereby forming a closure for the bag.A method also is provided of making a package using a bag as described above including the further steps of:Severing the sleeve adjacent to the closure to make a bag;Inserting an article or articles into the open end of the bag; andClosing the open end of the open end of such bag to form such package.
