<p>The procedure consists of using a film (1) of recyclable high-density polyethylene (HDPE) with mechanical properties that enable it to retain fold lines (1e, 1f, 1g, 1h) to make a sleeve or pack of basic parallelpiped shape that envelops a group of containers (P). The procedure consists of using a film (1) of recyclable high-density polyethylene (HDPE) with mechanical properties that enable it to retain fold lines (1e, 1f, 1g, 1h) to make a sleeve or pack of basic parallelpiped shape that envelops a group of containers (P). The film is between about 100 and 200 Microm thick, with a transverse rigidity of 200-240 daN/cm2> and no elastic memory. It is shaped by a series of folding operations and its overlapping edges (2) are welded or stuck together.</p> |
