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.

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&deg; C. and at high total draw ratios without fractures or tears. Containers suitable for food or beverage products may be produced from the laminates.
