A pouch-like container with faces made of materials having different consistencies and/or characteristics, particularly for solid, granular or fluid products. Conveniently, one of the two faces is produced from a scarcely flexible sheet (11), while the other face is produced from a much lighter and preferably transparent sheet in order to show the contained product. The low-flexibility face has ribs (17) to preset a deformability and set the final shape that the container will assume. The container is manufactured by coupling, along longitudinal lines (13, 14) (lateral borders) and transverse lines (15, 16), two sheets which are unwound continuously from two rolls. The tougher sheet (11) is pre-ribbed along lines (17) which force a controlled deformation, forming the container when it is filled with the product.
