    摘要: Provided are polymeric films that include a polyolefin and at least one cavitating agent including a poly(alkylene terephthalate) of formula (I); wherein n, representing the number of methylene segments in the repeating unit, is 3 or an integer greater than or equal to 5; p, representing the degree of polymerization, is an integer greater than 1. The polymeric film may be an opaque polymeric film. A preferred cavitating agent is poly(trimethylene terephthalate). Also provided are methods for making such polymeric films.
