Abstract: The biaxially oriented multilayered films include a stack (A-B)n of n layer units A-B, where n is greater than or equal to 32 each layer unit A-B having individual layers comprising a first layer A and a second layer B overlying the first layer A. The biaxially oriented multilayer films include intralayer voids within a portion of the individual layers in the stack. The intralayer voids have width-to-height aspect ratios from 20:1 to 500:1. The first layers of the layer units have a first composition, and the second layers of the layer units have a second composition. The first composition includes a first thermoplastic and a first polymer immiscible with the first thermoplastic. The second composition includes a second thermoplastic that may be the same as or different from that of the first thermoplastic.

Abstract: Embodiments of multilayer articles and methods of producing multilayer articles are disclosed. The multilayer articles include a stack (A-B)n of n layer units A-B, where n is greater than or equal to 64, each layer unit A-B comprising a first nanolayer A and a second nanolayer B overlying the first nanolayer A. The first nanolayer A of the layer units comprises a heterogeneous blend. The second nanolayer B of the layer units comprising a homogeneous material.

Abstract: Formable films are provided that include one or more biaxially-oriented polyethylene terephthalate layers. The formable films include a metaphase with a metaphase transition of about 180° C. to 200° C. as measured by differential scanning calorimetry (DSC). The formable films further include a molded volume of greater than 200%. Laminate structures including the formable films and processes for producing and using the formable films and laminate structures are also provided.
