The front tab is coplanar with the front wall and either (1) completely unconnected thereto or (2) weakly connected thereto. The rear tab is coplanar with the rear wall and connected thereto through a localized line of film weakening which is comparatively stronger than (2) above. The individual bags may be bonded together through the tabs. The pack has suspension means in association therewith.
