Claim 11:
12. A coated glass pharmaceutical package comprising:
a glass body having a Type 1 Class glass composition according to ASTM Standard E438-92 wherein the glass composition has at least a class A2 base resistance or better according to ISO 695, at least a type HGB2 hydrolytic resistance or better according to ISO 719 and a Type 1 chemical durability according to USP <660>,
the glass body having and an interior surface and an exterior surface and a wall extending therebetween; and
a lubricous coating having a thickness of less than or equal to 90 nm positioned on at least a portion of the exterior surface but not on any portion of the interior surface, wherein:
the portion of the exterior surface of the coated glass pharmaceutical package with the lubricous coating has a coefficient of friction that is at least 20% less than an uncoated glass pharmaceutical package formed from the same glass composition;
a horizontal compression strength of the coated glass pharmaceutical package is at least 10% greater than an uncoated glass pharmaceutical package formed from the same glass composition; and
the coefficient of friction of the coated glass pharmaceutical package is a maximum coefficient of friction measured relative to a second coated glass pharmaceutical package in a vial-on-vial testing jig under a normal load of 30 N, the second coated glass pharmaceutical package formed from the same glass composition and comprising the lubricous coating on at least a portion of a second exterior outer surface of the second coated glass pharmaceutical package and subjected to the same environmental conditions prior to measurement,
wherein the lubricous coating is a polymer.
