The blank of a flexible packaging envelope comprises a sheet folded on itself and forming two panels (22) linked by a transverse folding line (24), the longitudinal edges (26) of the two panels (22) being mutually secured along linking lines (28) provided on either side of the transverse folding line (24). End zones (30) of the two panels (22) bordering said transverse folding line (24) are folded down against the main part of one of the panels (22), links being provided at the edges (34) of said end zones (30), on either side of the transverse folding line (24), between said end zones (30) and the longitudinal edges (26) of the two panels (22). The packaging envelope is obtained by turning the blank inside out. The invention is useful for packaging ground coffee. |
