Glass articles with low-friction coatings
First Claim
1. A pharmaceutical package comprising:
- a glass body enclosing an inner volume and having an exterior surface, wherein the glass body is formed from a borosilicate glass that meets the Type 1 criteria according to USP <
660>
; and
a low-friction coating on the exterior surface of the glass body, the low-friction coating comprising;
a coupling agent layer having a first thickness less than or equal to 100 nm disposed on the exterior surface of the glass body; and
a polymer layer having a second thickness of less than 50 nm positioned over the coupling agent layer, wherein the exterior surface of the glass body with the low-friction coating has a coefficient of friction less than or equal to 0.7.

Abstract
A pharmaceutical package may include a glass body enclosing an inner volume and having an exterior surface. The glass body may be formed from a borosilicate glass that meets the 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. A coupling agent layer having a first thickness less than or equal to 100 nm may be disposed on the exterior surface of the glass body. A polymer layer having a second thickness of less than 50 nm may be positioned over the coupling agent layer. The exterior surface of the glass body with the coupling agent layer and the polymer layer may have a coefficient of friction less than or equal to 0.7.
