POLYMERIC FILMS AND METHODS TO MANUFACTURE SAME

摘要

Polymeric films are provided. The films comprise an ethylene-derived resin that has a density of about 0.905 to about 0.945 g/cm3, a compositional distribution breadth index (CDBI) of at least 50%, a melt index (MI) of about 0.1 to about 5.0 g/10 min and a branching index (g') of greater than about 0.7. The film may further comprise a propylene-derived resin having a density of about 0.86 to about 0.91 g/cm3. The films have excellent mechanical and optical properties and double-bubble extrusion processability.
