PTFE Cap Liner Films for Pharmaceutical Packaging
PTFE cap liner films create a chemically inert barrier between closure system and pharmaceutical media, helping to protect sensitive formulations and ensure reliable sealing performance. Our solutions are designed to reduce extractables, prevent contamination and support long-term stability in demanding pharmaceutical environments.
In pharmaceutical packaging, even minimal interaction between drug formulations and closure materials can impact purity and product safety. Cap liner performance therefore becomes critical, especially when working with aggressive media, biologics or highly sensitive formulations.
Why PTFE Cap Liners
Standard cap materials may interact with pharmaceutical media, potentially leading to contamination, degradation or reduced product stability. PTFE cap liners provide a nonreactive, impermeable protection layer that isolates the formulation from the closure and ensures consistent performance over the full product lifecycle. Yet, thermoformability is a big challenge were many materials fail. Our high-end skived PTFE protective films provide excellent thermoformability for secure and reliable performance.
Key Benefits of PTFE Cap Liner Films
When pharmaceutical products require the highest levels of purity, safety and reliability, closure system performance cannot be compromised. Our PTFE films are specifically engineered to protect the formulation while supporting reliable converting and processing performance.
The key benefits of our PTFE films are that they:
- Provide a chemically inert barrier between cap and media
- Provide excellent thermoformability to various shapes and forms
- Reduce extractables, leachables and contamination risk
- Ensure tight and reliable sealing integrity over time
- Resist aggressive solvents and sensitive pharmaceutical media
- Support long-term storage stability of critical formulations
