Abstract

See full text

A pack of self-opening serially-arranged plastic bags of the 'star-seal' type defining eight superimposed wall layers in the bag. Mounting tabs form a part of top portions of each of the eight layers and are positioned in superimposed positions and each includes an aperture for mounting the tabs on a tab retaining device of a rack in a non-front-side-free manner. Each of the tabs includes a mechanism for rendering the tab detachable and providing a predetermined detaching strength. In one embodiment, each of the tabs are detachable from the rack and in another embodiment, each of the tabs are detachable from the bag. A frangible bond is formed between the rear layer and the front layer of each successive bag in the pack. This frangible bond has a predetermined strength (1) which is greater than the predetermined detaching strength of two of the tabs and (2) is weaker than the predetermined detaching strength of the remaining six tabs to allow the leading bag of the pack (when pulled by a user for removal) to disengage from the pack, while (before disengagement) pulling the succeeding bag in the pack to cause detaching of the two leading of the tabs for self-opening of the succeeding bag.
