摘要：
A drug capsule and a method for making a drug capsule for a drug delivery device, such as an auto injector or needle-free injector, with improved stability and container closure integrity. The injector comprises a drug capsule sealed by a piston fabricated from PTFE modified by the inclusion of a co-polymer of PPVE, preferably in an amount less than 1% by weight, resulting in better performance while the device is stored and subjected to temperature cycling.
