International Classification:

B32B 2708

US Classification:

428 16, 428 11, 428 357, 428 366, 428 367, 428212, 428213, 428332, 428412, 428480, 428483, 4285428

Abstract:

Co-processable multi-layer laminates having a high T layer and at least one low T 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 T 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 T 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 T 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 T material used to impart these improved properties to the laminate.

International Classification:

C09K 1900
B32B 2734
B32B 108

US Classification:

428 15

Abstract:

Multilayer laminates including films, sheets, preforms, containers and other articles having at least one wholly aromatic, amorphous, stretchable liquid crystalline polymer layer with at least one non-polyester thermoplastic polymer layer are provided as well as methods for producing and stretching the multilayer articles. The laminates are suitable for thermoforming and stretch blow molding applications and may be stretched at temperatures lower than the molten state of the liquid crystal polymer and at high total draw ratios without fractures or tears. Containers suitable for food or beverage products may be produced from the laminates.

Abstract:

Multilayer laminates including films, sheets, preforms, containers and other articles having at least one wholly aromatic, amorphous, stretchable liquid crystalline polymer layer with at least one non-liquid crystalline thermoplastic polyester layer are provided as well as methods for producing and stretching the multilayer articles. The laminates are suitable for thermoforming and stretch blow molding applications and may be stretched to at least 100 percent elongation at temperatures below 200. degree. C. and at high total draw ratios without fractures or tears. Containers suitable for food or beverage products may be produced from the laminates.
