Abstract
A completely openable fluidtight packing wrapper for pasty products and in particular food products such as processed cheese. This wrapper comprises a shell having a bottom (2) of triangular shape bordered by two lateral walls (6, 7) and a wall forming a heel (8). A tearing element (24) comprises two tearing strips (25, 26) each extending in a first portion (27, 32) along one of the lateral edges (22, 23) of the heel (8) and in a direction parallel to this edge and, in a second portion (28, 33) along one of the lateral edges (4, 3) of the bottom (2) and in a direction parallel to this edge, these two strips (25, 26) being at least partly superposed in a third portion (29, 34) in the vicinity of the point (30) of the triangular bottom (2) so as to constitute a single pulling tongue (31) which extends beyond the sheet (1) forming the shell.
