Publication number: 20250011533Abstract: The polyester compositions of the invention are useful in the manufacture of shrinkable films. The shrinkable films of the invention are comprised of polyester compositions comprising certain combinations of glycols and dicarboxylic acids in particular proportions which provide a lower level of shrinkage while having a melting temperature to accommodate modern sorting and recycling technologies.Type: ApplicationFiled: April 5, 2022Publication date: January 9, 2025Applicant: Eastman Chemical CompanyInventors: Mark Allen Peters, Huamin Hu, Marc Alan Strand, Jacob E. Napierala

Patent number: 12116452Abstract: A blend composition comprising a first polyester and a second polyester. The first and second polyesters each comprises residues of terephthalic acid, neopentyl glycol (NPG), 1,4-cyclohexanedimethanol (CHDM), ethylene glycol (EG), and/or diethylene glycol (DEG). The first polyester comprises NPG, CHDM, and DEG in a combined amount that is less than the second polyester. The blend composition can be useful for producing a shrink film exhibiting high ultimate shrinkage (e.g., >65% at 95° C. for 10 seconds) and a high strain induced crystalline melting point (e.g., greater than 190° C.).Type: GrantFiled: October 8, 2019Date of Patent: October 15, 2024Assignee: Eastman Chemical CompanyInventors: Mark Allen Peters, Jacob E. Napierala, Rondell Paul Little, Jr., James Carl Williams, James Wesley Peer
