Patent number: 6426128Abstract: Co-processable multi-layer laminates having a high Tg layer and at least one low Tg layer with layers having properties of high strength, lo- or no-haze, and transparency after processing into various multi-layer forms are useful for packaging and container applications. The multi-layer laminate has at least one low Tg layer of a first thermoplastic polyester having at least one crystallization rate inhibitor. The total amount of crystallization rate inhibitor is effective to prevent substantial haze in the low Tg layer upon heating. In most applications, the total amount of crystallization rate inhibitor also does not substantially inhibit strain-induced crystallization of the at least one low Tg layer when the laminate is stretched during processing. The multi-layer laminates of the invention have improved properties such as reduced shrinkage and/or high barrier properties, with a very small amount of high Tg material used to impart these improved properties to the laminate.Type: GrantFiled: January 6, 1998Date of Patent: July 30, 2002Assignee: HNA Holdings, Inc.Inventors: Robert M. Kimmel, Arno Ewald Wolf, John Arthur Penoyer, Douglas Duane Roth

Patent number: 6007898Abstract: Three dimensional fiber networks which are semi-rigid and dimensionally stable are made from textile fabrics that have projections and optional depressions which are compressible and return to their original shape after being compressed. The fiber networks are made by the thermo-mechanical deformation of textile fabrics that are in turn made from thermoplastic fibers. The fiber networks have particular utility as cushioning and impact absorbing materials.Type: GrantFiled: March 23, 1998Date of Patent: December 28, 1999Assignee: HNA Holdings, Inc.Inventors: Dai W.
