The bag of the invention is of the type constituted by means of a continuous band that is closed on itself by means of a longitudinal weld line, thereby defining a tubular body that can be divided up into modules corresponding to respective bags, in which, in said continuous band, there are longitudinal strips of non-mesh plastic alternating with longitudinal mesh strips, which are superposed in the edge regions thereof for joining to one another. The invention focuses on the fact that whilst the non-mesh strips are made from polyethylene the mesh strips are made from bioriented polypropylene, the continuous band incorporating, in correspondence with each line of superposition between the aforesaid strips, a narrow strip that is likewise made from polyethylene, adapted to the polypropylene mesh, which welds with the aforesaid longitudinal, wider strips of polyethylene via the holes in the mesh, fixing the latter. In this way, construction of the bag requires less raw material. |
