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 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. A tenacious inorganic coating may be positioned around at least a portion of the outer surface of the body. The outer surface of the body with the tenacious inorganic coating may have a coefficient of friction less than or equal to 0.7.
