Claim 32:
33. A method of making a coated pharmaceutical container, the method comprising the steps of:
applying a coating to an exterior surface of a pharmaceutical container but not on any portion of an interior surface of the pharmaceutical container, wherein the coating comprises a polymer, and wherein the pharmaceutical container comprises a glass composition that has Class HGA1 hydrolytic resistance when tested according to the ISO 720 testing standard; and
curing the coating by heating;
wherein:
the coating has a coefficient of friction less than or equal to 0.7, wherein the coefficient of friction is a maximum coefficient of friction measured relative to a second pharmaceutical container in a vial-on-vial testing jig under a normal load of 30 N, the second pharmaceutical container formed from the same glass composition and comprising the same coating and subjected to the same environmental conditions prior to measurement of the coefficient of friction;
the pharmaceutical container is thermally stable after heating to a temperature at least 260° C. for a time period of 30 minutes; and
the applying the coating comprises a dipping process, a spraying process, or both.
