To provide a polyolefin based resin film of high elastic modulus and a composition
for producing a polyolefin based resin film of high elastic modulus. The polyolefin
based resin film is characterized in that a polyolefin [A] having a weight average
molecular chain length of 2850 nm or more and a polyolefin wax [B] having a weight
average molecular weight of 700 to 6000 have been compounded in a ratio of [A]/[B]=90/10
to 50/50 (by weight) as the resin component, and 10 to 300 parts by weight of inorganic
fillers have been added to 100 parts by weight of the resin component.
