To help narrow down the right partner for your project, let me know:
Are you looking for rigid protective inserts (mushrooms) or flexible films/pouches (algae)?
What is your estimated order volume or application?
Yes. There are several credible suppliers using mycelium (mushroom roots) or algae/seaweed to replace petroleum-based plastic packaging.
Strongest suppliers to investigate
Ecovative / Mushroom Packaging — Probably the strongest option if you need protective molded packaging such as inserts, trays, corner protection, or foam replacements. Their Mushroom® Packaging uses mycelium plus agricultural material (hemp hurd), is plastic-free, and is designed to be home compostable. They currently accept custom packaging opportunities at 10,000+ units/year.
EcoEnclose — Interesting if you're looking for flexible packaging rather than molded protective foam. Their portfolio includes seaweed-based packaging alongside paper packaging and other alternatives.
AlgaEarth — A St. Louis-based company developing algae-based packaging, including flexible packaging, wraps and trays. Their site describes the materials as biodegradable and customizable for food, retail and industrial applications.
OXO Packaging — Offers seaweed-based films, foams and molded packaging, including custom packaging. This could be worth investigating if you need something closer to conventional plastic film or flexible packaging.
My recommendation
If your goal is to replace Styrofoam/EPS or molded plastic inserts, I'd start with Mushroom Packaging/Ecovative. They have the most established commercial track record of the options I found, and their material is specifically engineered as a protective packaging replacement.
If your goal is to replace plastic bags, pouches, films, or food packaging, I'd investigate the algae/seaweed suppliers instead.
If you tell me what you're packaging, approximate dimensions, annual quantity, and whether it's food-contact, I can narrow this down to 3–5 suppliers that can actually manufacture your specific packaging, including U.S. suppliers and estimated MOQ/cost ranges.
Absolutely. There are several suppliers worth looking at, but mushroom/mycelium packaging is currently much more commercially mature than algae/seaweed packaging.
Mycelium / mushroom packaging
mushroompackaging.com — Probably the strongest place to start. They make molded protective packaging from mycelium + agricultural byproducts, specifically as an alternative to Styrofoam and petroleum-based protective foams. Their material is designed to be home-compostable. They offer custom packaging and work with brands on prototyping and production.
grown.bio — Netherlands-based manufacturer and Ecovative technology licensee, focused on custom mycelium packaging.
magicalmushroom.com — UK/EU manufacturer of molded mycelium packaging and an Ecovative licensee.
biofab.nz — New Zealand-based mycelium packaging company serving the Australia/New Zealand region.
One important point: Ecovative says it is currently not actively reviewing applications for additional MycoComposite licensees, so if you're looking to buy packaging, I'd approach the existing manufacturers rather than trying to license the technology yourself.
Algae / seaweed packaging
seasoltec.com — Particularly interesting if you're looking for food-service packaging. They're developing a plastic-free seaweed coating for paper used in sandwich wraps, pizza boxes, donuts, etc. As of 2026, they're in pilot/field testing, with commercial launch targeted for Q4 2026.
Seaweed is a little different from mycelium: today's commercially available solutions tend to be films, coatings, sachets, or food-service packaging, rather than rigid molded protective inserts.
What I'd recommend
If you tell me what you're packaging (e.g. cosmetics, electronics, food, bottles, clothing, medical products) and roughly how many units per month, I can narrow this down to 3–5 suppliers that can actually manufacture it at your volume, including U.S. suppliers and approximate pricing/MOQs.
