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.
