Title:
BIAXIALLY ORIENTED POLYESTER FILM FOR IN-MOLD MOLDING
Document Type and Number:
Japanese Patent JP2013063650
Kind Code:
A
Abstract:
To provide a polyester film that can perform in-mold molding accompanied by large transformation even if orientation is performed to attain a sufficient thickness precision.
This biaxially oriented polyester film for in-mold molding is characterized in that breaking ductility at 120°C is 350-500%, rupture stress is 10-30 MPa, and thickness unevenness is 5% or less. The biaxially oriented polyester film for in-mold molding has a polyester film composed of a laminated film of polyethylene terephthalate (A) which contains 4-15 mol% of diethylene glycol residues with respect to all glycol components and amorphous polyester (B).
