1. A coated glass pharmaceutical package comprising:
a glass body formed from one of a borosilicate glass composition that meets Type 1 criteria according to USP <660> or an alkali aluminosilicate glass having a Class HGA 1 hydrolytic resistance when tested according to the ISO 720-1985 testing standard;
the glass body having an interior surface and an exterior surface and a wall extending therebetween; and
a low-friction coating bonded to 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 low-friction coating has a coefficient of friction of less than or equal to 0.7, the coefficient of friction 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 low-friction 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 of the coefficient of friction;
the portion of the exterior surface of the coated glass pharmaceutical package with the low-friction coating contains less than 6 glass checks per 5 mm length when abraded along a length of about 20 mm with the second coated glass pharmaceutical package in the vial-on-vial testing jig under a second normal load of 10 N and after exposing the coated glass pharmaceutical package and the second coated glass pharmaceutical package to a temperature of at least about 260° C. for 30 minutes; and
the low-friction coating comprises:
a polymer; and
a coupling agent.
