ETFE Films for Vial Stoppers and Syringe Plungers
ETFE films create a high-purity barrier between rubber stopper or plunger components and pharmaceutical media. They help reduce extractables, particulates and contamination risk while supporting complex thermoforming and reliable plunger functionality.
This application is especially relevant in prefilled syringes and other drug delivery systems where direct rubber-to-media contact can affect purity, stability and dose consistency like in biologics, vaccines, smooth plunger glide and high-speed automation.
Why ETFE for Syringe Plungers and Vial Stoppers
Our ETFE films provide a high-purity, chemically inert barrier between the rubber plunger and the drug formulation. This eliminates direct rubber-to-media contact and helps create a cleaner, more stable environment than uncoated rubber for sensitive pharmaceutical applications.
Key Benefits of ETFE Barrier Films
The main benefit of our special films is their combination of drug protection with functional performance. Their excellent thermoformability, wrinkle-free lamination, high chemical resistance, low-friction surfaces and support for automated manufacturing make these films truly special. The ETFE materials provide key benefits for demanding applications, as they:
- Reduce extractables, particulates and contamination risk
- Create high-purity, chemically inert barriers
- Provide excellent thermoformability for complex geometries
- Create low-friction surface for smooth plunger movement and dose delivery
- Support high-speed automation in plunger manufacturing
Their strong resistance, excellent chemical and mechanical properties and high-end C-treatment availability for increased bondability make them ideal for fast and easy processing in modern pharmaceutical manufacturing processes.
