Sway Seaweed Packaging
Flexible film made with a regenerative resource
Materials that replenish the planet
FROM SEA TO SOIL
Created with Sway’s TPSea™ technology: a first-of-its-kind resin made entirely from seaweed and plants. It can be blended with other compostable polymers through various manufacturing techniques to create a wide variety of end products.
OPTIMIZED FOR EXISTING INFRASTUCTURE
Replicates the essential performance characteristics of plastic packaging and seamlessly integrates with existing infrastructure.
PLASTIC FILM REPLACEMENT
Replaces traditional LDPE plastic with a translucent, durable, moisture-resistant alternative that is majority biobased and responsibly sourced.
SWAY POLYBAG
Made from seaweed, plants, and compostable polymers
This polybag solution is made with a planet-replenishing resource: seaweed. Sway Polybags are durable, protective, lightweight, and designed to protect goods in transit from your factories to your customers.
Currently, the Sway Polybag is best suited to package dry items like apparel, outdoor gear, personal care, accessories, and home goods.
Are you searching for an eco-friendly option to replace thin film plastic?
Sway’s regenerative seaweed packaging replicates the essential performance characteristics of plastic packaging and integrate with existing infrastructure, allowing for scale and competitive pricing.
Sway’s materials aim to replenish life from sea to soil. They partner with a global network of ocean farms, from commercial suppliers to small-scale farmers, supporting coastal communities and healthy ecosystems.
WHAT WE OFFER
A Sustainable Alternative to Thin Film Plastic
FROM SEA TO SOIL
|
Sway’s supply chain is designed to generate holistic value, from sea to soil. They source responsibly farmed seaweed from around the world. Farmers harvest and dry the seaweed, then sell to biorefineries who treat the seaweed and extract the natural polymers. Sway then creates proprietary formulations at Sway Labs in the SF Bay Area. All of their products are designed for compatibility with traditional plastic manufacturing processes. Using this equipment, Sway’s compounding partners transform their formulation into a melt-processable pellet that they call TPSea™. TPSea™ can be extruded on its own, or combined with other compostable polymers to create a variety of products. In the case of the Sway Polybag, a TPSea™ blend is extruded into rolls of flexible film. Atlantic then transforms these rolls of film into their final format and add print customization in the process, if desired. |

OPTIMIZED FOR INFRASTRUCTURE
|
TPSea™, or thermoplastic seaweed resin, is a first-of-its-kind pellet made entirely from seaweed and plants. TPSea™ is Sway’s core technology, and the heart of their product portfolio. This resin can be blended with other compostable polymers through various manufacturing techniques to create a wide variety of end products. TPSea Flex™ is a translucent, durable, moisture-resistant flexible film — and is the first of many products created with Sway’s TPSea™ resin. |

PLASTIC FILM REPLACEMENT
|
Created from a blend of TPSea™ and home compostable polymers, TPSea Flex™, or thermoplastic seaweed film, is designed to meet the technical performance of traditional thin film plastics — while adding value at every step of the supply chain, from sea to soil. This film is durable, moisture resistant, and is well suited for high volume accounts across verticals. Key features of the film are that it’s lightweight, durable, and translucent. Use cases include conversion into polybags, poly mailers, and retail bags. |

BUILDING A FUTURE TOGETHER
This is just the beginning!
Sway is a material innovation company on a mission to bring materials made from abundant, planet-replenishing resources into the mainstream. Their first product – the Sway Polybag – is an entirely new technology that Atlantic Packaging has adopted to showcase a next-generation solution that could viably replace the 180 billion polybags used annually in the fashion industry alone. While that is an enormous amount of plastic to offset by itself, this packaging format is just the first step in a much more ambitious vision.
Together, Sway and Atlantic Packaging are working toward a myriad of solutions to reduce and replace plastics. From flexibles to rigids, food-grade to waterproof, we are actively exploring the technical boundaries of what Sway technology can do, now and in the future. Right now, we are focusing on scaling this technology for a relatively straightforward application: polybags. But we’re eager to develop Sway films that are food-grade, because we agree that the most promising applications for compostable packaging are in food-contact items. It’s going to take refining our first products like Sway Polybags to get us to a place where we can really bring food-contact films to life.
It’s also going to take radical collaboration with experts across policy, the compost industry, and science to design solutions that leave a legacy, not waste. Unlike many compostable packaging solutions on the market today, we believe that Sway products are themselves beneficial to compost, enriching it with nutrients not found in other biomaterials. That said, we know that the compost landscape is complex, and we’re committed to working with composters to increase acceptance of regenerative materials like ours. The Sway Polybag as we know it today represents an entry point to solving the broad array of plastics present in our everyday lives.
By scaling seaweed-based next-generation materials, we can transform entire supply chains, reducing demand for harmful petrochemicals while actively healing natural systems.
“Atlantic’s partnership with Sway presents an incredibly exciting opportunity to introduce the market to a thin film made from regenerative materials as an alternative to uniquitous plastic film.”
