摘要：
A monoaxially-oriented polymeric film material formed from an impact copolymer and having increased toughness relative to films that are monoaxially-oriented at conventional temperatures. A process for imparting high cross machine toughness to polymer films comprises forming a film; subjecting the film to monoaxial orientation, drawing the film; tempering the film, and annealing the film.
