FAQ
Why We Made It
Each year, unthinkable amounts of retail bags cycle through a flawed system, creating waste that burdens landfills and pollutes waterways. Paper is a wonderful solution, but lacks durability. Reusables are ideal, when we remember to bring them (and if we use them enough times to justify their resource intensity). It's time for a solution that provides the best functions of plastic while remaining gentle on our planet.
Sway created this bag to optimize inputs, use, and afterlife. Made with regenerative, renewable, and compostable ingredients – seaweed, plants, and certified home compostable polymers – it's engineered just enough: stronger than paper, but won't last forever like plastic. After its original use, this bag should be reused as many times as possible, then composted via home or industrial systems. Better yet, use it as a compost bin liner for truly circular impact!
How It's Made
STEP #1: FORMULATION
Sway is an ingredient brand. At our lab in the San Francisco Bay Area, we develop breakthrough formulations through continuous prototyping, rigorous testing, and lab-scale production trials. Our team is constantly innovating!
STEP #2: MANUFACTURING
We partner with established domestic manufacturers who utilize standard plastic processing equipment. These partners compound and extrude our biobased formulations into high-performance pellets and flexible films.
STEP #3: DISTRIBUTION
Our network of packaging distributors (EcoEnclose, A New Earth Project, and Atlantic Packaging) transform our finished materials into packaging for brands across industries — from fashion and sports, to cosmetics and personal care, and beyond. We're just getting started!

Formulation
This material (TPSea Flex™) is majority biobased, combining our 100% biobased pellet technology (TPSea™) with certified home compostable polymers.
End of Life
Sway packaging is home and industrial compostable, breaking down cleanly without microplastics or toxic residues. If compost is not available, please dispose of it in the trash. This packaging is not recyclable.
TPSea Flex™, the material used to make this bag, is constantly evolving. Sway certifies commercial-ready materials through the global gold-standard certification, TUV Austria. Formal certification is a time- and resource-intensive process, taking approximately a year to complete. This is why you may see some bags labeled as "certification pending."
TPSea Flex™ 1.0 has achieved TUV Home & Industrial Compost certification. TPSea Flex™ 1.1 and beyond are formulated entirely from certified compostable ingredients. Please inquire with our team for the latest certification status.
