PTFE Cap Liner Films for Pharmaceutical Packaging
PTFE cap liner films form a chemically inert barrier between the closure system and pharmaceutical media, helping to safeguard sensitive formulations and ensure dependable sealing performance. Our solutions are developed to minimise extractables, prevent contamination and support long-term stability in demanding pharmaceutical settings.
In pharmaceutical packaging, even the slightest interaction between drug formulations and closure materials can affect purity and product safety. Cap liner performance is therefore crucial, particularly when handling aggressive media, biologics or highly sensitive formulations.
Why PTFE Cap Liners
Standard cap materials may interact with pharmaceutical media, potentially resulting in contamination, degradation or diminished product stability. PTFE cap liners offer a non-reactive, impermeable protective layer that separates the formulation from the closure, guaranteeing consistent performance throughout the entire product lifecycle. However, thermoformability is a significant challenge where many materials fall short. Our premium skived PTFE protective films deliver outstanding thermoformability for dependable and secure performance.
Key Benefits of PTFE Cap Liner Films
When pharmaceutical products demand the highest standards of purity, safety and reliability, closure system performance cannot be compromised. Our PTFE films are expertly engineered to protect the formulation whilst ensuring reliable converting and processing performance.
The main advantages of our PTFE films are that they:
- Provide a chemically inert barrier between cap and media
- Offer excellent thermoformability to various shapes and forms
- Reduce extractables, leachables and contamination risk
- Guarantee tight and reliable sealing integrity over time
- Resist aggressive solvents and sensitive pharmaceutical media
- Support long-term storage stability of critical formulations
