1. A coated glass container comprising:
a glass body formed from an alkali aluminosilicate glass having a Class HGA 1 hydrolytic resistance when tested according to the ISO 720-1985 testing standard or a borosilicate glass that meets the Type 1 criteria according to USP <660>, the glass body having a first surface and a second surface opposite the first surface, wherein the first surface is an exterior surface of the glass body; and
a coating disposed on at least a portion of the exterior surface of the glass body, the coating comprising a polymer and a coupling agent, wherein the polymer comprises a polyimide, the coupling agent comprises a silsesquioxane, and the coated glass container reduces particle generation when the coated glass container undergoes processing,
wherein the coated glass container demonstrates at least a 50% reduction in average glass particle count for generated glass particles compared to an average particle count of generated glass particles by an uncoated glass container that undergoes the processing, wherein the average glass particle count is computed for glass particles equal to or greater than 10 μm and glass particles equal to or greater than 25 μm using light obscuration according to United States Pharmacopoeia Standard 788 and the % reduction is determined for the sum of the average glass particle count for glass particles equal to or greater than 10 μm and the average glass particle count for glass particles equal to or greater than 25 μm.
