摘要:
A polyester film is described, including a first polyester and a second polyester. The weight ratio of the first polyester to the second polyester ranges from 1:1 to 1:3. The glass transition temperature of the first polyester is higher than 140° C. and that of the second polyester is lower than 140° C.

摘要:
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.
