ABSTRACT:
A pack of articles (2) packaged using a plastic material film (3) having a preferred direction of tearing (D), a plurality of articles (2) being disposed side by side in one or more superposed layers, the film being folded over along a winding direction (E) around the articles which it retains, opening means being provided on the film to facilitate the tearing thereof. The means for opening the film (3) comprise a continuous zone of weakening (A), which zone is oriented transversely to the preferred direction of tearing (D), and forming a band (6) which surrounds the pack, this zone of weakening (A) having a mechanical strength which is sufficiently high to bear the traction stresses exerted on the film to retain the articles, but sufficiently low to permit opening of the film, without a tool, at any point whatsoever of the zone.
