  • a glass body comprising a first surface and a second surface opposite the first surface, wherein the glass body is a glass container formed from a Type 1B glass composition and the first surface is an exterior surface of the glass container; and

    a low-friction coating positioned on at least a portion of the first surface of the glass body, the low-friction coating comprising;

    a polymer layer comprising a polymer selected from the group consisting of polyimides, fluoropolymers, silsesquioxane-based polymers, and silicone resins; and

    a coupling agent layer disposed between the polymer layer and the first surface of the glass body, wherein;

    the coated pharmaceutical package is thermally stable at a temperature of at least about 260°
