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 after use.

With seaweed as its hero ingredient, every Sway Polybag helps support healthy ecosystems and communities. Seaweed is an abundant, fast-growing crop that can improve ocean health, boost biodiversity, and support thriving coastal communities.

FAQ

Why We Made It

Each year, 180 billion plastic polybags are used by the fashion industry alone. With low recycling rates, 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 during shipping, ensuring orders arrive to retailers and individuals in pristine condition. Sway Polybags aim to maintain these necessary performance qualities, while generating benefits for ocean health, coastal communities, and soil.
