Glass laminates with improved flatness and methods for forming the same

A glass laminate comprising:

• a non-glass substrate comprising a first surface and a second surface opposite the first surface;
• a glass sheet laminated to the first surface of the non-glass substrate;
• and
• a barrier film laminated to the second surface of the non-glass substrate and comprising a first surface adjacent to the non-glass substrate, a second surface opposite the first surface, and a thickness of at most about 0.5 mm,
• wherein the second surface of the barrier film defines an outer surface of the glass laminate, wherein the glass sheet has a thickness of at most about 0.5 mm;
• wherein an absolute value of a flatness of the glass laminate determined according to European Standard EN 438 after exposure to 23 C and 90% relative humidity for 7 days is at most about 3 mm/m.

A glass laminate comprising:

• a non-glass substrate comprising a first surface and a second surface opposite the first surface;
• a glass sheet laminated to the first surface of the non-glass substrate;
• and
• a multi-layer barrier film laminated to the second surface of the non-glass substrate and comprising a metal layer and a polymer layer;
• wherein an absolute value of a flatness of the glass laminate determined according to European Standard EN 438 after exposure to 23° C. and 90% relative humidity for 7 days is at most about 3 mm/m.
