LAMINATE AND FUSED OBJECT

摘要

PROBLEM TO BE SOLVED: To provide a laminate fusible to polypropylene by a high frequency welder of which the surface is provided with a layer comprising polypropylene having heat resistance and flexibility and not containing a resin having a polar functional group and the polar functional group, and a fused object wherein the laminate and polypropylene are fused by the high frequency welder. SOLUTION: The laminate is constituted of at least a three-layered structure wherein a B-layer, an A-layer and a C-layer are laminated in this order. The A-layer and the B-layer are directly laminated so that the B-layer becomes an outer surface and the B-layer of the laminate and the D-layer of the following film are arranged so as to be superposed one upon another in opposed relationship. The superposed part of the B-layer and the D-layer can be fused within a temperature range from 40 deg.C to a temperature lower than a lower melting point among the melting point of polypropylene (1) containing no functional group of the B-layer and the melting point of polypropylene (2) of the D-layer by 10 deg.C by the high frequency welder. The fused object is also disclosed.
