| 摘要 |
A gas barrier laminate (10) of the present invention includes a biaxially-oriented polypropylene base (1) and an aluminum oxide thin film (2) formed on one surface of the biaxially-oriented polypropylene base (1). The biaxially-oriented polypropylene base (1) has a plane orientation factor ”P ranging from 0.005 to 0.020 according to phase-contrast measurement. Further, the gas barrier laminate (10) of the present invention includes a biaxially-oriented polypropylene base (1) and an aluminum oxide thin film (2) formed on one surface of the biaxially-oriented polypropylene base (1). The biaxially-oriented polypropylene base (1) has a molecular chain whose orientation angle measured by phase-contrast measurement ranges from 50° to 90° or from -50° to -90° relative to an MD direction. |
