Abstract

PURPOSE:To obtain the titled film having excellent dimensional stability with heat and useful for the bonding of substrate for packaging material, by forming a polymer mixture composed of a propylene (co)polymer and a styrene (co)polymer at a specific ratio. CONSTITUTION:The objective film is produced by forming a polymer mixture composed of (A) 50-95wt.% of at least one kind of propylene (co)polymer and (B) 5-50wt.% of at least one kind of styrene (co)polymer e.g. by casting, inflation, T-die extrusion or calendering.
