摘要： Down-hole tools, methods of manufacturing the down-hole tools and methods of running the down-hole tools downhole are generally described herein. The down-hole tools generally include a sealing assembly adapted for use down-hole, wherein the sealing assembly includes: a substrate including an elastomeric material; and a heat shrink film adhered to at least a portion of the substrate, wherein the heat shrink film includes a thickness when adhered to the at least a portion of the substrate in a range of about 7.5 mil to about 30 mil and exhibits an Elmendorf tear strength (as measured by ASTM D-1922) in a range of about 1000 g to about 5000 g.
