The objective of the present invention is to create: an easily releasable multilayer film which exhibits easy releasability even if the thermal fusion bonding temperature is increased, and which has a seal strength that is capable of withstanding a pressure from the outside (an external pressure) and a pressure from the inside (an internal pressure) even at temperatures higher than room temperature; and a package which is obtained using this easily releasable multilayer film. The present invention relates to an easily releasable multilayer film which is characterized by being composed of: a laminate layer which contains a linear low-density polyethylene (A); an intermediate layer which contains an ethylene polymer (B); and a thermal fusion bonding layer which is formed from an olefin polymer composition (C) that contains 71-97% by weight of a propylene polymer (C1), 3-21% by weight of a medium-density polyethylene (C2) having a density of 0.930-0.945 g/cm3 and 0-8% by weight of an ethylene·α,&bgr;-unsaturated carboxylic acid copolymer (C3) (provided that (C1) + (C2) + (C3) = 100% by weight). |
