| titleOfInvention | Multilayer elastic film structures |
| abstract | An air-cooled multilayer elastic blown film structure, the film comprising: A. A first layer comprising 40 to 80 percent by weight of the film structure, the first layer comprising: (1) 50 to 85% by weight of a propylene-based copolymer having substantially isotactic propylene sequences, the propylene-based copolymer comprising 84 to 91 percent by weight of units derived from propylene and 9 to 16 percent by weight of units derived from ethylene, having the propylene-based copolymer a melt flow rate (MFR) of 0.1 to 10 g / 10 min according to ASTM D-1238 (230 ° C / 2.16 kg), a heat of fusion of 2 to 50 Joules / gram , a molecular weight distribution (Mw / Mn) less than 4, and a density of 0.855 to 0.876 g / ml; and (2) from 50 to 15 percent by weight of a linear low-density polyethylene copolymer having a melt index (MI) of 0.1 to 10 g / 10 minutes according to ASTM D-1238 (190 ° C / 2 , 16 kg) and a density of 0.900 to 0.923 g / ml; and B. a second layer comprising from 10 to 30 percent by weight of the film structure, the second layer comprising: (1) from 55 to 85 percent by weight of a linear low-density polyethylene copolymer having a density of 0.918 to 0.928 g / ml and having a melt index (MI) of 0.1 to 9 according to ASTM D-1238 (190 ° C / 2.16 kg); and (2) 15 to 45 percent by weight of a linear low-density polyethylene copolymer having a density of 0.900 to 0.923 g / ml and a melt index (MI) of 0.1 to 10 g / 10 minutes. according to ASTM D-1238 (190 ° C / 2.16 kg); and (3) optionally, 1,000 to 20,000 ppm of antiblock additive, the film structure exhibiting: (a) a dart impact value of at least 8.66 g / μm (220 g / mil) per ISO 7765-1 , (b) an Elmendorf tear strength of at least 4.53 g / μm (115 g / mil) in the machine direction per ASTM D-1922, (c) an Elmendorf tear strength of at least 10 , 6 g / μm (270 g / mil) in the transverse direction per ASTM D-1922, (d) an elastic recovery of at least 78 percent in the transverse direction after being extended to a strain of 200 percent of its original length, and (e) a final holding force in a roof stretch test of at least 4.83 MPa (700 psi) (after a high stretch test (200% -175%)), |
