Abstract:
Delamination resistant glass containers with heat-tolerant coatings are disclosed. In one embodiment, a glass container may include a glass body having an interior surface, an exterior surface and a wall thickness extending from the exterior surface to the interior surface. At least the interior surface of the glass body is delamination resistant. The glass container may further include a heat-tolerant coating positioned on at least a portion of the exterior surface of the glass body. The heat-tolerant coating may be thermally stable at temperatures greater than or equal to 260° C. for 30 minutes.
Abstract:
The glass containers described herein have at least two performance attributes selected from resistance to delamination, improved strength, and increased damage resistance. In one embodiment, a glass container with resistance to delamination and improved strength may include a body having an inner surface, an outer surface and a wall thickness extending between the outer surface and the inner surface. At least the inner surface of the body may have a delamination factor less than or equal to 10. The glass container may further include a compressively stressed layer extending from the outer surface of the body into the wall thickness. The compressively stressed layer may have a surface compressive stress greater than or equal to 150 MPa.
Abstract:
Coated pharmaceutical packages are disclosed. In embodiments, a coated pharmaceutical package may include 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. The coated pharmaceutical package may be thermally stable at a temperature of at least about 260° C. for 30 minutes. 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.
