METALLOCENE-PRODUCED VERY LOW DENSITY POLYETHYLENE AND LOW DENSITY POLYETHYLENE BLENDS |
摘要 |
The present invention provides a polymer blend suitable for use as a film or a coating, the polymer blend including from 1 to 99% by weight of a metallocen e- produced VLDPE polymer having a density less than 0.916 g/cm3, and from 1 to 99% by weight of an LDPE polymer having a density of from 0.916 to 0.928 g/c m3 wherein the sum of (a) and (b) is 100%. The VLDPE polymer can have a melt index of from 6 to 15 dg/min, or from 9 to 12 dg/min. The present invention further provides polymeric films extrusion cast from such polymer blends, an d articles having a flexible substrate and a polymeric film extrusion-coated o n the substrate.
