Sway Polybags

Seaweed, plants, and home compostable polymers.

Sway Polybags are durable, protective, lightweight, and designed to protect goods in transit from production to your doorstep. While this bag performs like plastic, it lasts only as long as it's needed, returning to nature through home or industrial composting. Currently, the Sway Polybag is best suited to package dry items like apparel, outdoor gear, personal care, accessories, and home goods.

Not yet. The material ingredients are food contact safe, but the material itself is awaiting compliance confirmation to ensure food stays fresh inside.

Seaweed is a regenerative marine crop that contains natural polymers, the building blocks of Sway’s material portfolio. Compared to common renewable packaging inputs like corn, potato, or sugarcane, the benefits of seaweed truly go above and beyond!

Unlike terrestrial crops farmed through conventional agriculture systems, seaweed thrives off sunlight and seawater, requiring low to no inputs. It’s abundant, fast-growing, space-efficient, and available on nearly every coastline. Seaweed can also generate a lot of good as it grows: increasing habitat for marine life, boosting biodiversity, and mitigating climate change impacts like ocean acidification and erosion. Plus, new science suggests that seaweed can sequester substantial amounts of carbon.

Sway works with trusted sourcing partners located all over the world, including in Indonesia, Chile, Puerto Rico, Mexico, Madagascar, and beyond.

Responsibly cultivated macroalgae and extracts. Sway prioritizes diversification in their sourcing to avoid over-reliance on any region or species, and support the positive impacts of expanded seaweed cultivation around the globe.

Sway sources seaweed around the world, from commercial suppliers to small-scale farmers in emerging blue economy zones. While impact looks different with every supplier, depending on the regional context and cultivation methods, their comprehensive seaweed sourcing framework universally commits to:
1. Protect and enhance ecosystem services
2. Employ non-extractive, sustainable harvest techniques
3. Ensure zero introduction of plastic or synthetic substances into natural environments
4. Support cultivation in open, integrated ecosystems
5. Preserve critical habitat integrity
6. Prioritize farmer welfare

The material is over 50% biobased and constantly improving.

EcoEnclose’s current priority is to utilize Sway’s groundbreaking technology to replace LDPE film in polybags and retail bags. If you are interested in applications outside of an LDPE bag replacement, contact the Sway team at team@swaythefuture.com.

Based on our experience to date, these bags have a shelf life of 18 months when stored in cool, dry conditions. With continued shelf-life testing, we will soon have more rigorous testing on this question.

Weather-proof – yes; waterproof – no. This packaging can withstand some moisture (think humidity and exposure to rain in transit), but is not waterproof or suited to package moist/perishable items.

Yes, with certification pending. Sway designs for home and industrial compostability, certifying their products through the global gold-standard certification, TUV Austria. Formal certification is a time and resource intensive process – Sway only pursues this when their formulations are market-ready, which is why we say this material is "certification pending." However, along their product development journey, Sway materials undergo rigorous testing via in-house methods, third party labs, and field composting partners (like Cold Creek Compost) to ensure full breakdown within <180 days (home compost standard) and <90 days (industrial compost standard). This gives us high confidence their materials will pass certification with flying colors!

Per TUV Austria certification standards, Sway materials compost safely into carbon dioxide, water, inorganic compounds, and biomass – no microplastics, distinguishable remnants, or toxic residues behind. Early testing has even shown small amounts of Nitrogen, Phosphorus, and Potassium – the 3 main nutrients plants need to grow!

Nope! These bags are designed to keep items fresh, clean, and seaweed-scent-free.
