A continuous bag strip, particularly applicable for use in bag dispensing machines, of the type consisting of a flat, continuous, conventional tubular strip of a flexible plastic material, fitted in each of the longitudinal edges with an inward longitudinal fold and which has several groups of equidistantly separated transverse lines at a distance equal to the length of the bag, and consisting of a welding line which makes up the bottom of each bag and a perforation line near the welding line, so as to be able to separate each bag from the others is disclosed. On each inward fold line for each longitudinal fold, an oblong, longitudinal opening is made by die cutting. This opening is parallel to the longitudinal edge of the strip, so the longitudinal edges of each oblong opening are located in such a way that there is one on each side of the inward fold line. One of the transverse edges of the oblong opening is on the perforation line or between this line and the corresponding, adjacent welding line which makes up the bottom of the bag, while the other transverse edge is generally semi-circular. |
