Film, laminated film and laminated structure

A laminated film (LF-1) comprising:

• (i) a layer containing a propylene resin having a modulus of elasticity in bending at 23°C. of from about 1300 to 2800 Mpa;
• and
• (ii) a layer containing a propylene block copolymer having (A) and (B) components;
• wherein the propylene block copolymer is prepared by a process comprising the steps of:
• (I) carrying out copolymerization of propylene with ethylene until the content of the component(A) reaches from about 40 to 85% by weight based on the total weight of the component(A) and the component(B) defined below, said component(A) being a propylene-ethylene copolymer component having an ethylene content (EA) of from about 1.5 to 6.0% by weight:
• (II) carrying out copolymerization of propylene with ethylene in the presence of the component(A) prepared in step (I) until the content of the component(B) reaches from about 15 to 60% by weight based on the total weight of the components (A) and (B), said component(B) being a propylene-ethylene copolymer component having an ethylene content (EB) of from about 7 to 17% by weight;
• provided that the intrinsic viscosity, (η)B, of the component (B) is from about 2 to 5 dl/g, and the ratio of (η)B to the intrinsic viscosity, (η)A, of the component(A), namely, (η)B/(η)A, is from about 0.5 to 1.8;
• and further provided that said propylene resin excludes a propylene block copolymer which has a modulus of elasticity in bending at 23° C. of not lower than about 1300 Mpa.
