<p>An extruded plastics material net bag, formed by a tubular body which in the flattened state defines two superimposed sheets, in each of which there are two reinforced longitudinal lateral web portions close to the lateral edges of the bag and a reinforced longitudinal central web portion substantially equidistant between the other two; the bag handles are extensions of the lateral web portions and are provided with a weld line at the end thereof while a weld line defines the bottom of the bag. The bag is closed either by way of a filiform member capable of throttling the mouth of the bag or by two closing appendices, one on each sheet and which extend beyond the bag mouth, being joined together by knotting, stapling or any other means. The special location of the lateral web portions and the existence of the central web portion provide more strength and a greater dimensional stability to the full bag.</p> |
