Patent number: 8431232Abstract: Disclosed are hot-melt adhesives prepared from aromatic-aliphatic polyesters containing terephthalic acid in combination with adipic acid, glutaric acid, or a mixture thereof, as diacid components and a diol component containing 1,4-butanediol, 1,6-hexanediol, or a combination thereof. These adhesives set up rapidly within a well-defined temperature window. The hot-melt adhesives can be used in a variety of applications, but are especially suited as seaming adhesives for roll-applied labels. These adhesives have melting temperatures and crystallization properties that allow their application at temperatures cool enough to prevent curling and premature shrinkage of the shrink label during seaming, and yet produce strong label seams that can withstand the elevated temperatures of a shrink tunnel without sacrificing line speed. Also disclosed are labeled containers and a process for applying a roll-on, shrink label to a container using the hot-melt adhesives of the invention.Type: GrantFiled: October 12, 2009Date of Patent: April 30, 2013Assignee: Eastman Chemical CompanyInventors: Marcus David Shelby, Scott Ellery George, Gary Robert Robe, Freddie Wayne Williams, Michael Eugene Donelson, Joshua Seth Cannon, Candace Michele Tanner
