FILM PREPARED FROM PLASTICIZED POLYESTER
PROBLEM TO BE SOLVED: To provide a method of producing a soft and flexible film or sheet having Tg of lower than 23°C and Tm of more than 120°C, wherein the method can prevent the blocking of the film or sheet and the sticking to the roll in a step of processing the film or sheet.SOLUTION: A film or...

| description | PROBLEM TO BE SOLVED: To provide a method of producing a soft and flexible film or sheet having Tg of lower than 23°C and Tm of more than 120°C, wherein the method can prevent the blocking of the film or sheet and the sticking to the roll in a step of processing the film or sheet.SOLUTION: A film or sheet having a glass transition temperature below about 23°C and a melting temperature greater than about 120°C is prepared by first preparing a polyester composition of: about 50 to about 95 wt.% of a base copolyester having a melting temperature of less than about 220°C and exhibiting more than about 1% crystallinity after annealing for 2,000 minutes at a temperature at which the base copolyester has a maximum crystallization rate; and about 5 to about 50 wt.% of a plasticizer suitable for use with the base copolyester. The polyester composition is formed into a film or sheet. During formation of the film or sheet or afterwards, crystallization is induced to provide the soft and flexible film or sheet. |
