Flexible, durable, lightweight bags for shipping and shopping.

It’s time for a material revolution. At Sway, we believe the ocean can be a hero in this future. We use abundant, fast-growing seaweed to create compostable replacements for the most hard-to-recycle, single-use plastics.
Sway technology scales through legacy manufacturing systems, uplifting green jobs and the blue economy in the process.

"This is one of the coolest things we've ever done. Everyone I've shown, from friends to people in the industry, have been so stoked on it."
- JOHN JOHN FLORENCE,
FOUNDER & 3x WORLD SURF CHAMPION

"Where most brands think of packaging as trash, we are reframing packaging as an innovation initiative."

"Using Sway bags is like an embedded give-back program. It’s such an easy solution to implement — should be a no-brainer for brands, since we all need packaging."

"What a hopeful thought to envision the outdoor industry living their values with the adoption of circular, biobased packaging."



"What’s been most exciting is hearing from customers who love the look and feel of the packaging."
"It felt AMAZING. The package felt incredibly durable, yet soft and protective. Very surprised about how nice the bag was."

“Our operations team has been impressed with the durability of the bags and has not seen any difference in usability compared to traditional LDPE polybags.”


Sway was born from a love of the ocean, and a core belief that plastic’s gotta go. We’re a team of material scientists, designers, and sustainability experts — who double as surfers, sailors, hikers, and all-around-nature-lovers — driven to usher in a new age of materials.
Our community is building the movement for a thriving future — through material innovation, ocean health, and regenerative design.
