Abstract

A formable biaxially-oriented film includes a first layer. The first layer includes from about 10 to about 90 wt. % crystalline polyester and from about 10 to about 90 wt. % of a formability enhancer to assist in increasing the polymeric chain flexibility. The formability enhancer has a melting point less than about 230° C. The film has a MD and a TD Young's Modulus of at least 10% lower than a crystalline polyester film in the absence of the formability enhancer. The film may further include a second layer, which includes an amorphous copolyester. The second layer may be adjacent to or attached to the first layer.
