Very interesting! Until now, the low melting temperature of DCF has been a problem for heat sealing, but it looks like they have formulated a type of TPU that is weldable at a lower temperature – very cool. Unfortunately the price will be prohibitive for many people, but if someone manages to get a sample of several meters and wants to try making a packraft out of it, contact me and I will be happy to help! I am very curious to see how it performs.
