Laminate comprising polyolefin elastic film layer

A trilaminate comprising one polyolefin elastic film layer and two substrate layers;

• the polyolefin elastic film having the following properties:
• (1) an average integrated enthalpy sum of no greater than 17 J/g, according to the Thermal Analysis Method defined herein;
• (2) an average integrated enthalpy ratio of from 0.6 to 300, according to the Thermal Analysis Method defined herein;
• and
• (3) an unload stress at 75% strain of above 0.8 MPa according to the Hysteresis Test defined herein;
• and
• wherein the trilaminate has a normalized load force/normalized unload force ratio at 75% strain of 1 to 2.6 according to the Hysteresis Test defined herein;
• wherein the polyolefin elastic film layer comprises a first polyolefin elastomer, a second polyolefin elastomer, and a third polyolefin elastomer;
• wherein the first polyolefin elastomer comprises a blend of two random propylene-ethylene copolymers and has an overall crystallinity of about 6 wt %;
