20140270598 | Easy Open Apparatus and Method for Multi-Ply Bags - An easy open apparatus for multi-wall bags and a method for making such bags are disclosed. The bag has a closed end and an open end and the rear panel is stepped relative to the upper edge of the front panel. A tear-tape strip is adhered to an inner surface of a flap formed in the outer layer of the front panel and extends partly across the panel with ends of the tear-tape exposed. To open the bag, the user grasps one exposed end of the tear-tape and pulls it outwardly away from the bag, thereby tearing the outer paper layer across the flap to form a “pocket” or “handle” that the user may grasp to tear the bag open. | 09-18-2014 |
