摘要:
A coated glass pharmaceutical package includes a glass body having a Type 1 chemical durability according to USP 660, at least a class A2 base resistance or better according to ISO 695, and at least a type HGB2 hydrolytic resistance or better according to ISO 719, the glass body having an interior surface and an exterior surface and a wall extending therebetween. A lubricous coating having a thickness of less than or equal to 90 nm may be positioned on at least a portion of the exterior surface of the glass body but not on any portion of the interior surface. The portion of the coated glass package with the lubricous coating comprises a coefficient of friction that is at least 20% less than an uncoated glass package and the coefficient of friction does not increase by more than 30% after undergoing a depyrogenation cycle including exposure to a temperature of 250° C. for a time period of 30 minutes. A horizontal compression strength of the coated glass package is at least 10% greater than an uncoated glass package and the horizontal compression strength is not reduced by more than 20% after undergoing the depyrogenation cycle including exposure to a temperature of 250° C. for a time period of 30 minutes and then being abraded. The lubricous coating comprises a polymer.
