POLYPROPYLENE-BASED FILM WITH IMPROVED MECHANICAL AND SEALING PROPERTIES AND METHOD OF MAKING SAME |
摘要 |
<p>A polypropylene-based film comprising at least three layers characterized by two skin layers and at least one core layer, wherein the at least one core layer and/or at least one skin layer comprises a polymer blend of: (i) a first propylene-based polymer which comprises (A) at least 60 weight percent (wt %) units derived from propylene, and (B) from 5 to 40 wt % units derived from ethylene, and wherein the first propylene-based polymer is characterized by a melting temperature (Tm) of less than or equal to 110° C., and (ii) a second propylene-based polymer selected from the group consisting of rPP and hPP and characterized by certain mechanical and/or sealing properties is provided. Also provided is a method of making the polypropylene-based film.</p> |
