PROBLEM TO BE SOLVED: To provide a cleaning cover having high transparency, excellent in tensile strength, tear strength and glossy feeling and further having similar level of mechanical physical property even thicker than conventional monolayer film.SOLUTION: There is provided a cleaning cover or the like consisting of an air cooling inflation molded multilayer film by laminating a propylene-based resin layer (Z) mainly containing a component (B') inside a propylene-based resin layer (Y) mainly containing a component (B) outside an ethylenic resin layer (X) consisting of a component (A). Component (A): a copolymer of ethylene having property of MFR of 0.1 to 20 g/10 min ad density of 0.860 to 0.925 g/cmand α-olefin having 3 to 12 carbon atoms. Component (B), (B'): a propylene α-olefin random copolymer copolymerized by using a metallocene catalyst and having properties such as MFR of 1 to 10 g/10 min., melting peak temperature of 135 to 150°C and load deflection temperature of 85 to 105°C.SELECTED DRAWING: None |
