Patent number: 10086557Abstract: Disclosed is a method for manufacturing a film. 50 wt % to 85 wt % of a first polyester and 50 wt % to 15 wt % of a second polyester are dried and mixed to form a mixture. The first polyester is polyethylene terephthalate (PET), polyethylene naphthalate (PEN), or combinations thereof. The second polyester is copolymerized of 1 part by mole of terephthalic acid, m parts by mole of 1,4-cyclohexanedimethanol (1,4-CHDM), n parts by mole of 1,3-cyclohexanedimethanol (1,3-CHDM), and o parts by mole of ethylene glycol (EG). m+n+o=1, 0?o?0.4, 0.6?m+n?1, and 0.06?n/m?1.31. The mixture is melted and blended to form a polyester composition, which is extruded to form a sheet. The sheet is then biaxially stretched to obtain a film. The biaxially stretched film is then treated with a thermal setting.Type: GrantFiled: December 23, 2013Date of Patent: October 2, 2018Assignee: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Cheng-Hsing Fan, Chun-Yen Chen, Ming-Tsong Leu, Chien-Pang Wu
