An easy opening plastic bag includes a plastic front panel (12), a plastic rear panel (14), and plastic left and right end panels (16, 18) coupled to the front and rear panels. A plastic gusset (22) is formed at the top of the bag and is joined to the front, rear, left, and right panels. A first frangible portion (30) is disposed near a top of the front panel, and a second frangible portion (34) is disposed near a top of the rear panel. Tearing the first and second frangible portions allows a portion of the bag to rotate away from the remainder of the bag about an axis parallel to the tap wall of the bag. A third frangible portion (36) is provided in the bag and extends substantially perpendicular to the top wall.
