Soon California will be banning most petroleum-based plastic packaging from being shipped with products into the state. Five other states have EPR or packaging laws. More information here and here. This will require alternatives to most plastic packaging and foams. I’ve begun covering some bio-based plastic alternatives. See here.
In this context, meet Sway, a startup making bioplastic packaging from seaweed. First they convert the seaweed to resin pellets that they call TPSea resin. Then they create film packaging from the resin, called TPSea Flex Film. After that, they create polybags and clear bioplastic “windows” for packaging.
All of these seaweed-based bioplastics are 100% biobased, majority seaweed, and home compostable. Sway now has some customers using the products, and are seeking to pilot the products with other manufacturers. More on Sway here
