摘要： Unique blends of metallocene catalyzed polymers are disclosed. The blends of the invention include a first polyethylene having a narrow molecular weight distribution and a narrow composition distribution breadth index (CDBI), and a second polyethylene having a relatively broad molecular weight distribution and a very narrow CDBI. The blend is advantageously used when it includes 50 percent or greater of the first polyethylene and 50 percent or less of the second polyethylene. Blown film made from the blend will have an unexpectedly good set of optical properties.
