The invention relates to a bag (1) in the form of a double bag, consisting of at least two layers (E1 et E2) of material. Said layers are the same shape and have the same dimensions, are superposed and interconnected along the periphery (2-5) thereof in such a way that they define two pockets (P1 et P2) which are accessible by an opening (7) made in the longitudinal direction of the bag (1). Furthermore, the material forming at least one of the layers (E1 et E2) is extensible in the machine direction and/or in the cross-machine direction. |
