After years of development, the Sway Polybag is now being used by a suite of apparel and outdoor brands.

Made with seaweed, plants, and home compostable polymers, this bag is designed to protect items in transit. With seaweed as its hero ingredient, every Sway Polybag helps divert petroleum and support healthy ecosystems and communities. Seaweed is an abundant, fast-growing crop that can improve ocean health while providing climate-resilient employment in coastal regions. This renewable marine crop is plentiful in natural polymers, the building blocks of Sway’s material portfolio. When compared to common renewable packaging inputs like corn, potato, or sugarcane, the benefits of seaweed truly go above + beyond! Seaweed thrives off sunlight and sea water, requiring little to no inputs — unlike terrestrial crops, farmed through systems of industrial agriculture. It’s abundant, fast-growing, space-efficient, and available on nearly every coastline in the world. Plus, seaweed creates regenerative impact (giving back more than it takes) as it grows: increasing habitat for marine life, boosting biodiversity, and mitigating climate change impacts like ocean acidification and erosion. New science suggests that seaweed can also sequester substantial amounts of carbon!
