Extrusion Lamination

Extrusion lamination is common in the medical and aeronautical industries, but Sea to Summit pioneered its use in outdoor products. Liquid Thermoplastic Urethane is applied to the face fabric through an extrusion head, where it bonds permanently. The common process for creating an airproof barrier, where a film is rolled onto a fabric, is prone to delamination. The result: Sea to Summit sleeping mats are more reliable and longer-lasting.
