Abstract

Disclosed herein are glass containers which may include a glass body comprising an alkali aluminosilicate glass composition having a Class HGA1 hydrolytic resistance when tested according to the ISO 720:1985 testing standard. The glass body may have an interior surface and an exterior surface. A heat-tolerant coating may be bonded to at least a portion of the exterior surface of the glass body. The heat-tolerant coating may have a coefficient of friction of less than about 0.7 and is thermally stable at a temperature of at least 260° C. for 30 minutes. The heat-tolerant coating may comprise a polymer, and the heat-tolerant coating may have a thickness of less than or equal to 100 nm.
