Patent ID: 8691373

Claim:
A laminate (C) of a thermoplastic polymer composition comprising: at least one thermoplastic resin composition (A) having an air permeation coefficient of 10×10 −12 cc·cm/cm 2 ·sec·cmHg or less, laminated with at least one thermoplastic polymer composition (B) having a melt viscosity of 500-2000 Pa·s and a Young's modulus at a room temperature of 1-400 MPa, wherein the thickness of a layer of the thermoplastic resin composition (A) is 0.05-10 μm, the thickness of a layer of the thermoplastic polymer composition (B) is 0.1-100 μm and the air permeation coefficient of the laminate (C) of 20×10 −12 cc·cm/cm 2 ·sec·cmHg or less, wherein the thermoplastic polymer composition (B) is composed of a modified polymer composition (E) dispersed in a matrix of a thermoplastic resin composition (D).
