The invention relates to seals for rotary devices and methods of producing the same. In one aspect, a seal for a turbine engine (10) includes a seal body (38) disposed at a base of a turbine engine blade (22) and a wing portion (46) extending axially from said seal body. The wing portion has a first portion (52, 54) substantially parallel with a centerline (C) of the engine and an angled upturn portion (48). The first portion extends between the seal body and the angled upturn portion (48). An angle (A) between the engine centerline and the angled upturn portion (48) is between about 0 degrees and about 90 degrees.
