Abstract: A pack of plastic bags which are preferably self-opening are adapted to be mounted on a support rack and leave no residue on the support rack when removed therefrom. The plastic bags include front and rear walls integrally joined at their sides and secured at their bottoms and defining an open mouth portion at the top of the walls. A detaching central tab is formed at the top of each of the walls and each has an aperture therein for mounting the central tabs on a tab retaining device on the rack. The tab of at least the rear wall has a structure to propagate a tear through the tab for detaching the tab from the rack while retaining sufficient strength in the portion of the tab above the mounting aperture to prevent premature tearing of the tab and detaching from the rack.

Abstract: A bag dispensing system is provided which includes a rack for supporting a pack of plastic bags in a generally vertical suspended position for successively removal of the bags by a user and including an elongate central tab retaining device having a predetermined width. Each of the bags in the pack have front and rear walls integrally joined at their sides and secured together at their bottoms and define an open mouth portion at the top of the walls. A detaching central tab is formed at the top of each of the bag walls and each has an aperture therein for mounting the tabs on the rack retaining device.
