Abstract

Coated pharmaceutical packages are disclosed. In embodiments, a coated pharmaceutical package includes a glass body comprising a first surface. A low-friction coating may be positioned on at least a portion of the first surface of the glass body. The low-friction coating may include a polymer chemical composition. A light transmission through the coated pharmaceutical package may be greater than or equal to about 55% of a light transmission through an uncoated pharmaceutical package for wavelengths from about 400 nm to about 700 nm. The low-friction coating may have a mass loss of less than about 5% of its mass when heated from a temperature of 150° C. to 350° C. at a ramp rate of about 10° C./minute.

First claim

a polymer selected from the group consisting of polyimides, fluoropolymers, silsesquioxane-based polymers, and silicone resins; and
a coupling agent layer disposed between the polymer and the first surface of the glass body,

wherein the coefficient of friction of the portion of the coated pharmaceutical package with the low-friction coating is at least 20% less than a coefficient of friction of a surface of an uncoated pharmaceutical package formed from the same glass composition.

2. The coated pharmaceutical package of claim 1 , wherein a thickness of the low friction coating is less than or equal to 1 μm.

4. The coated pharmaceutical package of claim 1 , wherein
the coupling agent layer comprises a coupling agent; and
wherein the low-friction coating comprises a polymer layer positioned over the coupling agent layer, the polymer layer comprising the polymer.

5. The coated pharmaceutical package of claim 4 , wherein the coupling agent comprises at least one of:
a first silane, a hydrolysate thereof, or an oligomer thereof; or
a chemical formed from the oligomerization of at least the first silane and a second silane, wherein the first silane and the second silane are different.

6. The coated pharmaceutical package of claim 5 , wherein the first silane is an aromatic silane.

7. The coated pharmaceutical package of claim 1 , wherein the coupling agent layer comprises a silsesquioxane comprising an aromatic moiety and an amine moiety.

8. The coated pharmaceutical package of claim 1 , wherein the coupling agent layer comprises at least one of:
a mixture of a first silane and a second silane; or
a chemical formed from the oligomerization of at least the first silane and the second silane, wherein the first silane and the second silane are different.

9. The coated pharmaceutical package of claim 8 , wherein the first silane is an aromatic silane.

10. The coated pharmaceutical package of claim 1 , wherein the polymer is a polyimide.

11. The coated pharmaceutical package of claim 1 , wherein the coated pharmaceutical package is thermally stable at a temperature of at least about 260° C. for 30 minutes.

12. The coated pharmaceutical package of claim 1 , wherein the glass body comprises ion-exchanged glass.

13. A coated pharmaceutical package comprising:
a glass body comprising a first surface and a second surface opposite the first surface, wherein the glass body is a glass container and the first surface is an exterior surface of the glass container; and
a low-friction coating positioned on at least a portion of the first surface of the glass body, the low-friction coating comprising:
a polymer selected from the group consisting of polyimides, fluoropolymers, silsesquioxane-based polymers, and silicone resins; and
a coupling agent comprising at least one of:
a first silane, a hydrolysate thereof, or an oligomer thereof, wherein the first silane is an aromatic silane; or
a chemical formed from the oligomerization of at least the first silane and a second silane,

wherein:
the first silane and the second silane are different;
