Abstract:
Disclosed is a method for manufacturing a polyester film with low thermal expansion. 95 wt % to 55 wt % of crystalline polyester and 5 wt % to 45 wt % of amorphous polyester are mixed. The blend is then melt extruded to form a sheet. The sheet is then biaxially stretched to obtain a film. The biaxially stretched film is then treated with a heat-setting procedure.
