ETFE Films for Vial Stoppers and Syringe Plungers
ETFE films provide a high-purity barrier between rubber stopper or plunger components and pharmaceutical media. They help minimise extractables, particulates and the risk of contamination, while supporting complex thermoforming and reliable plunger performance.
This application is particularly important in prefilled syringes and other drug delivery systems where direct contact between rubber and media can impact purity, stability and dose consistency, as seen in biologics, vaccines, smooth plunger movement 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 advantage of our special films is their combination of drug protection with functional performance. Their outstanding thermoformability, wrinkle-free lamination, high chemical resistance, low-friction surfaces and support for automated manufacturing make these films truly exceptional. The ETFE materials offer key benefits for demanding applications, as they:
- Reduce extractables, particulates and contamination risk
- Create high-purity, chemically inert barriers
- Provide exceptional thermoformability for complex geometries
- Create low-friction surfaces for smooth plunger movement and dose delivery
- Support high-speed automation in plunger production
Their strong resistance, excellent chemical and mechanical properties and availability of high-end C-treatment for enhanced bondability make them ideal for quick and easy processing in modern pharmaceutical manufacturing processes.
