<P>PROBLEM TO BE SOLVED: To provide a polymer article such as a laminate, a film, a fabric and fiber including a low crystallinity layer and a high crystallinity layer. <P>SOLUTION: The article includes at least two layers of a low crystallinity layer and a high crystallinity layer. One or both the layers can be elongated so that a pre-stretched article can be formed, and includes at least an ethylene/α-olefin copolymer where the ethylene/α-olefin copolymer has Mw/Mn of 1.7-3.5, and has a particular melting point, fusion heat, elastic recovery, molecular fraction and a storage modulus. <P>COPYRIGHT: (C)2013,JPO&INPIT |
