Polyester film and method for producing the same, gas barrier laminated film |
| abstract |
To provide a polyester film using a biomass-derived material as a raw material, having excellent pinhole resistance, bag-breaking resistance, and little variation in physical properties in the longitudinal direction. Biaxially oriented polyester film comprising at least 60 to 95% by mass of polybutyleneterephthalate(A) and 5 to 40% by mass of polyethyleneterephthalate(B), wherein 60% by mass or more of raw material of (B) is ethylene glycol derived from biomass and dicarboxylic acid units derived from fossil fuel, and characterized by the following (1) to (4), (1) the piercing strength is 0.6 N / [mu]m or more. (2) the degree of plane orientation of the film is 0.144 to 0.160. (3) the heat shrinkage at 150 DEG C. of 0 to 4% in the longitudinal direction and -1 to 3% in the width direction. (4) the thickness accuracy in the longitudinal and width directions is 15% or less. |
