The first ever polybag made with TPSea Flex™, a groundbreaking film developed by Sway that sets the stage for a future in which packaging is derived from seaweed and not fossil fuels.

Unlike many other bio-based inputs on the market, responsibly farmed seaweed has the potential to be truly restorative to our planet by helping clean our seas, boost biodiversity, and build thriving coastal communities.

The Sway Polybag is a perfect solution for cutting-edge brands committed to circularity who pride themselves on adopting the world's most forward-thinking mater

This film is made with at least 50% TPSea™: a game-changing resin developed by Sway that is certified 100% bio-based and predominantly made with responsibly sourced seaweed. The remaining balance of the film is made with PBAT, a home compostable polymer.

This bag is already breaking boundaries, but it is just the beginning as Sway continuously works to increase seaweed and bio-based content.

Seaweed is an emerging packaging input with big regenerative potential. Most biobased packaging inputs (such as corn, sugarcane, potatoes, or wood chips) degrade soils, threaten biodiversity, require high volumes of freshwater, result in nitrogen and phosphorus runoff, or rely heavily on fossil fuels for production.

Seaweed is different. Seaweed cultivation requires no land, fresh water, or fertilizers to grow, while actually improving ocean health, strengthening marine life and biodiversity, and improving the livelihoods of the coastal communities.

Seaweed holds incredible promise, and Sway is paving the path towards making this material widely available long-term.

The polybag you’re holding is an early step in achieving this vision!
