Thermoplastic Seaweed Resin (TPSea™)
Biobased pellets designed to go anywhere plastic goes – with a couple big differences. TPSea™ comes from the ocean, and is designed to return to the soil.
Traditional plastics have been around for more than a century, during which time they’ve become perfectly optimized and heavily subsidized. This industry is primarily fueled by petroleum-based pellets that are melted and formed into finished products through global manufacturing. It’s a huge challenge to shift away from a well-oiled system. And also a huge opportunity.
After years of development, the Sway team is proud to share our breakthrough technology: TPSea™ – an entirely new, patented category of biopolymer resin that is home compostable and 100% derived from renewable sources. The #1 ingredient? Seaweed; a regenerative ocean crop that replenishes ecosystems as it grows.
These pellets are full of golden potential.
✓ Melt Processable
✓ Scalable
✓ 100% Biobased
✓ Majority Seaweed
TPSea™ clears previously unsurpassed hurdles in replacing petroleum-based pellets. With heat, it melts and stretches just like traditional thermoplastics. This enables TPSea™ to work with existing plastic manufacturing systems, unlocking a streamlined path to impact at scale.
With excellent technical performance, our patented biobased resin is an entrypoint to solving the broad array of plastics present in our everyday lives. To start, TPSea™ serves as the base of Sway’s TPSea Flex™ Film.
TPSea Flex™ Film
First-of-its kind seaweed packaging, designed for scale.
While today’s plastics wreak havoc at every stage of the supply chain, the evolution of single-use plastics stemmed from noble intentions: convenience, hygiene, flexibility. We embrace these characteristics with one more addition: What if plastic could heal ecosystems rather than harm?
For the first time, ubiquitous plastic packaging can be replaced with Sway’s patented flexible film made with TPSea™. Produced using globally scaled manufacturing, TPSea Flex™ provides all the technical performance brands require, while adding ecological and societal value along the way.
Pairing the benevolence of seaweed with advanced materials science, our inaugural TPSea Flex™ film is strong and versatile, well suited for a range of packaging applications across industries – from fashion to beauty to food and beyond. Sway’s evolving product portfolio made with TPSea Flex™ includes thin-film packaging applications such as polybags, retail bags, and food wrappers, a category representing approximately 30% of all single-use plastic packaging.
Delivers performance.
Decomposes naturally.
✓ Strong
✓ Versatile
✓ Luxurious Look & Feel
TPSea Flex™ is composed of seaweed, plants and compostable polymers. Strong and versatile, it can withstand a wide array of temperatures and exposure to moisture. The frosted finish is luxurious in both look and feel. Embodying true circularity, this material decomposes naturally in home, backyard, and industrial compost environments.
TPSea Flex™ represents the first big step towards a future we can all get behind – less plastic, more plants, and a healthier planet.
Firstwave™ Film
Made entirely from seaweed and plants, optimized for rapid decomposition back into Earth.
Did you know 5 trillion bags, wrappers, and pouches are made each year? That’s 160,000 bags every second! Many of these single-use plastics will only be used for mere seconds, but less than 3% are recycled – meaning the vast majority go to landfill or flow into nature.
That’s why we are committed to creating completely biobased, home compostable replacements for these pervasive flexible plastics.
Sway Firstwave™ film is our team's first pursuit towards a plastic-free future, using seaweed as our primary ingredient. By using a liquid-based production method, we’re able to honor seaweed’s inherent gelling properties. Ocean-farmed seaweed is harvested, processed, gelled, and cast into rolls of film suited for an array of solutions where flexibility and full transparency are desired. Unlike traditional plastics, Firstwave™ lasts only as long as it needs to before returning to nature as a soil amendment.
