<p>Disclosed is an easily tearable laminated film (1) suitable as a sealed pouch or a lid of a sealed container, which can be easily and reliably torn along a direction of any specific shape such as a linear shape, an annular shape, or a V shape in opening the pouch or the lid. This easily tearable laminated film (1) includes a porous organic resin film (2), a heat-fusible resin film (3), and an adhesive layer (4) interposed between these films (2, 3). The porous organic resin film (2) consists of a rigid organic resin film (5) whose entire surface has a large number of fine through and/or non-through pores (6), and has a higher tearability than that of an organic resin film (5) having no pores. The porous organic resin film (2) and the heat-fusible resin film (3) are bonded with a higher strength than the tear strength of the porous organic resin film (2) in a tear region (7) and with a strength not higher than the tear strength of the porous organic resin film (2) in an adjoining region (8a, 8b) adjacent to the tear region (7). <IMAGE></p> |
