Appl. No.:

09/795800

Inventors:

Eric Jon Moskala - Kingsport TN
Kevin Douglas Horton - Surgoinsville TN

Assignee:

Eastman Chemical Company - Kingsport TN

International Classification:

B32B 310

US Classification:

428141, 528298, 528302, 528307, 528308, 5283086, 524186, 524270, 524275, 524284, 524277, 524773, 2642884, 264292, 264200, 264300, 428143, 428147, 428148

Abstract:

A calendered film or sheet of a polyester resin composition has a haze value of less than 5 percent. The polyester resin composition comprises a polyester having a crystallization half-time from a molten state of at least 5 minutes and an additive comprising (i) a fatty acid or a salt of a fatty acid containing more than 18 carbon atoms and (ii) an ester wax comprising a fatty acid containing more than 18 carbon atoms with an alcohol containing from 2 to 28 carbon atoms, wherein the ratio of the fatty acid or salt of the fatty acid to the ester wax is 1:1 or greater. Also, the present invention is a process for producing such calendered film or sheet having a haze value of less than 5 percent. The steps of the process comprise (1) calendering such polyester resin composition, (2) forming on a calendering roll a film or sheet from such polyester resin composition, and (3) removing the film or sheet from the calendering roll at an angle of less than 90Â to form a film or sheet having a haze value of less than 5 percent.

US Classification:

525444, 525448, 428 349, 428 351, 428910

Abstract:

A compositional blend of from about 50 to about 99 weight percent of a polyester and from about 1 to about 50 weight percent of an essentially, linear, random aliphatic-aromatic copolyester or branched and/or chain extended copolyester thereof is useful as a heat-shrinkable film.

US Classification:

702130, 702 30, 264535, 425522

Abstract:

A method for determining the temperature distribution throughout the thickness of a preform used in a container reheat stretch blow molding process by measuring the outside surface temperature of a preform or series of preforms at least two times during the period the preform is cooling down after exiting the heat station and before entering the blow molding station in the blow molding machine and calculating the temperature distribution throughout the thickness of the preform based upon the measured outside surface temperatures using a novel algorithm.

US Classification:

524287, 524289, 524293, 264175, 2641761, 264212, 264291

Abstract:

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 weight percent of a base copolyester having a melting temperature of less than about 220 C. and exhibiting more than about 1 percent crystallinity after annealing for 2000 minutes at a temperature of which the base copolyester has a maximum crystallization rate; and about 5 to about 50 weight percent 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 a soft and flexible film or sheet.
