<p>A wrapper forming a bag especially for loose products consists of a thin sheet with folds (3, 34, 49) folded vertically to a lower folded wrapper which forms two walls connected with one another by at least one of their edges (4, 5) and a bottom (8), whilst an orifice (10) with edges is arranged opposite to said bottom (8). The folds (3, 34, 49), which form a folded part (13), comprise-closeby an edge (35) formed by folding a border before folding over the folds (3, 34, 49)-another temporary connection of walls (44, 45) of the folds (3, 34, 49) that are formed by connecting the first wall (44) with the second wall (45) of the fold (3, 34, 49) respectively. The third wall (43) of the fold (3, 34, 49) is arranged loosely against the second wall (44) of the fold (3, 34, 49) so as to allow extending of the folds (3, 34, 49) actuated by a traction originating in angles (9) of the bag and by retreating the first and second wall (44, 45) of the fold (3, 34, 49).</p> |
