STRENGTHENED GLASS CONTAINERS RESISTANT TO DELAMINATION AND DAMAGE

摘要

The glass containers described herein are resistant to delamination, have improved strength, and increased damage resistance. In one embodiment, a glass container 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 body may also have 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. A lubricous coating may be positioned around at least a portion of the outer surface of the body, such that the outer surface of the body with the lubricous coating has a coefficient of friction less than or equal to 0.7.
