PROBLEM TO BE SOLVED: To provide an oriented film excellent in appearance, inside visibility, designability or the like, including less fish-eyes with forming stability obtained by using a polybutylene terephthalate-based resin made by continuous polymerization method, and to provide a multi-layered oriented film and a bag-like packaging material with the same. SOLUTION: This oriented film is obtained by using a polybutylene terephthalate-based resin made by continuous polymerization method and contains <=20 pieces/100 cm<2> fish-eyes of >=20μm size in a film of the resin with 50μm thickness. The multi-layered oriented film is made by laminating the oriented film with other resin layer. The bag-like packaging material is made by heat-sealing the bottom and/or more than two sides of these oriented films. |
