Abstract (en)
A bag (10) includes a first panel (12) with at least one access hole (30) in it, and a second panel (14) without a hole corresponding to the at least one hole of the first panel. Preferably, two holes are present, more preferably near the bag mouth. The panels are substantially equal in length. The bag can be easily opened by bag opening means, without the need for vacuum or air to open the bag. According to the invention, a method for making such a bag includes the steps of: a) providing the lay-flat tubing (40) in a first lay-flat orientation; b) advancing the lay-flat tubing such that at least a portion of the lay-flat tubing is reoriented to a position at a right angle to its first lay-flat orientation; c) making the hole (30) in the reoriented tubing; d) further advancing the tubing (40) while reorienting the tubing back to its first lay-flat orientation; and e) sealing and cutting the reoriented tubing to make a bag (10) having a hole (30a) in a panel of the bag. <IMAGE>
