How It's Made
STEP #1: FORMULATION
Think of Sway like an ingredient brand. At our San Francisco Bay Area HQ, 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 manufacturers who scale Sway production using standard plastic processing equipment. These partners compound and extrude our formulations into high-performance pellets and flexible films.

STEP #3: DISTRIBUTION
Our network of packaging partners convert and customize rolls of Sway film into finished bags for brands across industries — from fashion and outdoors, to home goods and personal care, to tech and electronics, and beyond.
Formulation
This material (TPSea Flexâ„¢) is a mixture of seaweed, plants, and compostable ingredients. It is majority biobased, combining Sway's 100% biobased pellet technology (TPSeaâ„¢) with certified home compostable polymers.
End of Life
Sway packaging is designed for home and industrial compost, 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 Flexâ„¢, 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 Flexâ„¢ 1.0 has achieved TUV Home & Industrial Compost certification. TPSea Flexâ„¢ 1.1 and beyond are formulated entirely from certified compostable ingredients, with formal certification underway. Please inquire with our team for the latest certification status.
