Claim:
1. A glass article, comprising: a glass element having a thickness from about 50 μm to about 100 μm, the glass element further comprising: (a) a first primary surface; (b) a second primary surface; (c) a compressive stress region extending from the first primary surface of the glass element to a first depth in the glass element, the region defined by a compressive stress of at least about 150 MPa at the first primary surface of the glass element; (d) a maximum flaw size of less than or equal to 2 microns at the first primary surface of the glass element; and (e) a stress intensity factor (K) of less than or equal to 0.2 MPa wherein the glass element is characterized by: (a) an absence of failure when the glass element is held at a bend radius of about 20 mm for about 60 minutes at about 25° C. and about 50% relative humidity; (b) a puncture resistance of greater than about 3 kgf when the first primary surface of the glass element is loaded with a tungsten carbide ball having a diameter of 1.5 mm.
