PURPOSE:To obtain a laminated film which is superior in tear property, tear direction stability, cutting resistance and transparency, has favorable low- temperature heat seal properties and is suitable for high-speed automatic packing. CONSTITUTION:The title film possesses three layer structure of layers A, B, C, which is substantially a laminated film stretched laterally uniaxially, the layer B is constituted of a propylene polymer having a low melt index as the intermediate layer B, a propylene polymer having a high melt index is laminated to a cooling roll surface side of the layer B as the layer C and a heat seal layer comprised of an olefin polymer having a low melting point is laminated to its opposite side as the layer A. |
