Sway-Thermoplastic-Seaweed-Polybag_Vertical-2

The first truly scalable polybag solution made with a planet-replenishing resource: seaweed.

Sway Polybags are strong, protective, and lightweight. While this bag performs like plastic, it lasts only as long as it's needed, returning to nature through home or industrial composting.

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.

FAQ

Why We Made It
Each year, 180 billion plastic polybags are used by the fashion industry alone. Less than 3% of plastic bags are recycled meaning the vast majority end up in landfill, or as pollution in our waterways, wildlife, and even human bodies.
 
Many polybags can and should be eliminated, but have become a staple in supply chains worldwide due to their ability to protect products from dust and damage during shipping, ensuring orders arrive to retailers and individuals in pristine condition. Sway Polybag aim to maintain these necessary performance qualities, while generating benefits for climate, ocean health, and coastal communities.
