<p>The fruit and vegetable products bag comprises a continuous strip with plastics (2,6) and mesh (4) sectors with hot welds (3,5). The strip (1) is folded to form a tube with transverse weakening lines producing bags closed by hot welding and a string (9) of polyethylene not requiring high-temperature control. The bags can then be opened by minimum force to gain access to their contents.</p> |
