Abstract
A packing wrapper for packaging pasty products of parallelepipedic form. The wrapper comprises a foldable foil forming five faces (12) with dimensions substantially equal to the faces of the parallelepiped, and an opening device (18) for opening the packing wrapper by tearing it. The device consists in a foil of foldable material having an active portion (22) consisting in a single strip of a constant width substantially equal to that of one face (12) with parallel longitudinal outer edges arranged substantially along the sides of at least one face (12) to be torn; a tongue (20) of reduced width, defined by two parallel longitudinal edges, integral with the active portion (22), disposed at one end of the single strip and forming a grasping portion extending beyond the wrapper; and a central cutout (24), the profile of which matches that of the tongue, disposed at the other end of the active portion.
