Preferably, two holes are present, preferably near the bag mouth. The panels are substantially equal in length. The bag can be easily opened by described bag opening means, without the need for vacuum or air to open the bag. The bag can be used in conjunction with otherwise conventional taped bag systems. A method of making the bag, a bag opening system, a method of opening the bag, and a packaging system are also disclosed.
