Laminated films

A laminated film having two outermost layers, the laminated film comprising,

• a layer A containing a resin composition comprising (i) 20-100% by weight of an amorphous polyolefin containing at least one component, of an amount of at least 50% by weight in said amorphous polyolefin, selected from the group consisting of propylene and butene-1, the amorphous polyolefin having a boiling-n-heptane insoluble of 70% by weight or less and a number-average molecular weight of 1,000-200,000, and (ii) 80-0% by weight of a crystalline polypropylene, and
• a layer B.sub.1 containing a crystalline polypropylene,
• wherein the two outermost layers are constituted each by the layer B.sub.1.

A laminated film having two outermost layers, the laminated film comprising,

• a layer A consisting essentially of a resin composition comprising (i) 20-100% by weight of an amorphous polyolefin containing at least one component, of an amount of at least 50% by weight in said amorphous polyolefin, selected from the group consisting of propylene and butene-1 and (ii) 80-0% by weight of a crystalline polypropylene, and
• a layer B.sub.2 containing an ethylene (co)polymer resin,
• wherein at least one of the two outermost layers is the layer B.sub.2.
