Heat-sealable polypropylene blends and methods for their preparation |
摘要 |
This invention relates to blends of polypropylene and styrene-terpene copolymers which provide biaxially oriented, corona discharge treated, heat-sealable films useful in the packaging art. Preferably the compositions also contain a saturated fatty amide, e.g., stearamide slip agent and/or a Fischer-Tropsch wax. A process is described when the films after biaxial orientation, are treated by a corona discharge and in some cases heat aged prior to use in the packaging art.
