<P>PROBLEM TO BE SOLVED: To solve a problem in which peeling occurs at the interface different from the desired interface and partial peeling occurs at the different interface following peeling at the desired interface when a polyethylene layer of both outer layers and the thermoplastic polyurethane layer are peeled, in a laminate where both the outer layers are layers formed out of polyethylene and an intermediate layer is the thermoplastic polyurethane layer. <P>SOLUTION: In the laminate having at least the thermoplastic polyurethane layer and layers formed out of polyethylene in both the outer layers adjacent to the polyurethane layer, peel strength between the layer formed out of polyethylene and the thermoplastic polyurethane layer can be adjusted and peeling easily occurs only at the desired interface using the layer formed out of polyethylene different in crystallization heating value in both the outer layers. <P>COPYRIGHT: (C)2013,JPO&INPIT |
