<p>A biaxially oriented multilayer film, able to prevent gaps between the film and a package containing a product or wrinkles and to wrap in a predetermined way while preventing smell from being transferred to the product, comprised of a base layer formed by a propylene-based polymer and surface layers formed by a propylene-based resin on the two surfaces of the base layer, wherein a heat shrinkage rate R1 in a length direction and a heat shrinkage rate R2 in a width direction when heating at 120 DEG C for 15 minutes: <DF NUM="(a)">R1 = (L1H-L2H)/L1H </DF> <DF NUM="(b)">R2 = (L1W-L2W)/L1W </DF> <DF NUM="(c)">0.08≤R1≤0.20 </DF> <DF NUM="(d)">0.08≤R2≤0.20 </DF> <DF NUM="(e)">¾R1-R2¾≤0.05 </DF> where, L1H: length before shrinkage in length direction, L2H: length after shrinkage in length direction, L1W: length before shrinkage in width direction, L2W: length after shrinkage in width direction</p> |
