Patent ID: 7498086

Claim:
A film comprising (A-i) a polyetherimide resin having repeating units of the following structural formula (1), (A-2) a polyetherimide resin having repeating units of the structural formula (2), (B) a polyarylketone resin having a melting peak temperature of 260 degrees C. or higher, and a filler in an amount of from 5 to 50 parts by weight, based on total 100 parts by weight of (A-1), (A-2) and (B), wherein a weight ratio of the resin components, [(A-1)+(A-2)]/(B)], ranges from 65/35 to 45/55 and a weight ratio, (A-1)/(A-2), ranges from 70/30 to 50/50; wherein, the film has a heat bonding property at a temperature of 260 degrees C. or lower and an edge tearing resistance of at least 50 MPa in both a longitudinal direction and a transversal direction.
