F-217 Liners
Prevent leaks and maintain product integrity
As the inventors of the industry-standard F-217 closure liner, we know what it takes to engineer foam-based liners that deliver on critical performance attributes for any application.
- Wide range of foam densities to meet performance objectives
- Thickness: 20 – 125 mils
- Smoother liner surfaces for improved sealing
- Polyolefin foam options: LDPE, HDPE, LDPE/EVA, and PP
- Available in rolls or die-cut pieces
- Vented liner options
- Compatible with PET, PE, PP, PVC, PS, glass, aluminum, and steel containers
- Standard or custom message printing
- Modest O2 and moisture barrier
- Leak prevention
- Sustainable options
Our three-layer coex construction with solid skins and a foamed core offers smoother contact surfaces for improved sealing compared to mono-layer alternatives.
