A perforation blade is used for cutting a perforated tear line in a bag to form an easy-open corner portion. The perforation blade includes a base formed to span the corner portion of the bag. The base has a first end adapted to extend to the end edge of the bag proximate a seal line, and a second end adapted to extend to one side edge of the bag. A series of closely spaced perforation teeth are formed with the base, and are adapted to penetrate the first and second walls of the bag to form a corresponding series of perforations at the corner portion of the bag. A starter tooth is formed at the first end of the base, and is adapted to cut a starter nick in a skirt of the bag between the end edge and the proximate seal line. A burst protection gap is formed between the starter tooth and a first of the series of perforation teeth. The burst protection gap is adapted for safely receiving the seal line of the bag to prevent severing the seal line when cutting the perforations.
