    • Processes for enhancing blown film processability and the blown films formed thereby are described herein. One embodiment of the processes generally includes providing a first propylene based heterophasic copolymer having a first melt flow rate, modifying the first propylene based heterophasic copolymer to form a second heterophasic polymer having a second melt flow rate, wherein the second melt flow rate is greater than the first melt flow rate, contacting the first heterophasic polymer, the second heterophasic copolymer or a combination thereof with a plurality of additives, wherein the plurality of additives include a nucleator, polyethylene and mineral oil to form a modified heterophasic copolymer and blowing the modified heterophasic polymer into a film.

    • It has been discovered that the properties of sheet or film materials of broad molecular weight distribution ethylene/propylene rubber impact-modified heterophasic copolymer (ICP) can be improved by blending the ICP with a second polyolefin. The second polyolefin may be a syndiotactic polypropylene (sPP), a random copolymer (RCP) of propylene and comonomer (e.g. ethylene and/or butene) made using a Ziegler-Natta or metallocene catalyst, medium density polyethylene (MDPE), linear low density polyethylene (LLDPE), or low crystalline copolymer of propylene/α-olefin. Improvements include, but are not necessarily limited to, reduced motor amps, lower secant modulus, increased dart drop strength, increased gloss, reduced haze, increased elongation to yield, elimination of stress whitening, improved puncture resistance, and decreased seal initiation temperature. This sheet of film materials may be co-extruded with other resins or laminated with other materials after extrusion.
    • 已经发现,通过将ICP与第二聚烯烃共混可以提高宽分子量分布乙烯/丙烯橡胶冲击改性多相共聚物(ICP)的片材或薄膜材料的性能。 第二聚烯烃可以是间同立构聚丙烯(sPP),使用齐格勒 - 纳塔或茂金属催化剂制备的丙烯和共聚单体(例如乙烯和/或丁烯)的无规共聚物(RCP),中密度聚乙烯(MDPE),线性低密度 聚乙烯(LLDPE)或丙烯/α-烯烃的低结晶共聚物。 改进包括但不限于减少的电动机放大器,较低的正割模量,较高的飞镖下落强度,增加的光泽度,降低的雾度,增加的屈服伸长率,消除应力增白,改进的抗穿刺性和降低的密封起始温度。 这片薄膜材料可以与其它树脂共挤出,或者在挤压后与其它材料层压。
