Patent ID: 7741408

Claim:
A polymer blend consisting of the following: A) an elastomer selected from a homogeneously- or a heterogeneously-branched ethylene/alpha-olefin interpolymer having a density of less than, or equal to, 0.905 g/cm 3 ; B) a random propylene/ethylene copolymer having a melting point (Tm) by Differential Scanning Calorimetry (as measured by ASTM D-3417) of less than 160° C.; C) from 200 ppm to 1300 ppm, based on the weight of the composition, of a peroxide crosslinking agent; and D) a melt strength enhancing polymer which is a is low density polyethylene (LDPE) with a melt strength of greater than 3 cN; and E) at least one additive selected from the group consisting of antioxidants, phosphites, U.V. stabilizers, cling additives, slip agents, antiblock additives, plasticizers, colorants, pigments, carbon black masterbatch, organic fillers, inorganic fillers, silicon polymer, and combinations thereof; and wherein the blend has an Embossability Index (EI) greater than 0.48, at thermoforming temperatures from 144° C. to 156° C., and wherein the blend does not contain a free radical coagent.
