PERMEABLE POLYMERIC FILMS AND METHODS OF MAKING SAME
摘要
<p>A method of making a film and the resulting film are disclosed. A matrix polymer comprising at least 20 wt. % nylon-6 is combined with moisture-absorbing particles and mixed in an extensional flow mixer to disperse the moisture-absorbing particles in the matrix polymer. The mixed composition is formed into a film comprising at least 20 wt. % matrix polymer and 1 wt. % moisture-absorbing particles. The film is oriented in at least one direction by a ratio of at least 1.2:1 to provide an unperforated, oriented film having a thickness of at least 20 microns and a water transmission rate of at least 24 g/m2/hr. The film is useful in food casing applications.</p>
