Abstract
An improved easy opening pinch bottom or gusset bag is provided. The bag includes opposed front and back panels and opposed pairs of front and rear gusset panels foldably connected to one another. The rear gusset panels and the rear panel are of a sufficient dimension to fold over the front panel to close the bag. A tear strip is secured to the front panel at a location to be overlapped by the rear gusset panels and the rear panel when the bag is closed. The portions of the rear gusset panels and the rear panel that will lie adjacent the tear strip in the closed condition of the bag are provided with short perforation lines to facilitate the initial advancement of the tear strip through the rear gusset panels and the rear panel. These perforation lines extend only a short distance so that the overall strength of the bag is not adversely affected.
