Tri-Seal is the inventor of F-217, for coextruded, closure-liner material for a wide variety of containers material types and products. F-217 is available in multiple thickness and densities to enhance sealing performance and torque retention. Tri-Seal also offers F 828 and F 8268 which offer heat resistance for hot-fill applications.
Our liners feature:
- Trouble-free performance. Our closure liners are highly compressible which reduces closure back off and makes up for bottle finish variations.
- Customized liner construction, with several resin options available. Liners can be tailored in thickness, density and resilience.
- Our foam product line also offers enhanced barrier film construction to address specific product requirements
