I am looking for a plastic alternative supplier that uses algae or mushrooms for packaging.

Innovative suppliers are using fungi (mycelium) and algae (seaweed) to create true, biodegradable alternatives to traditional plastics.

Mushroom (Mycelium) Packaging Suppliers

Mycelium packaging utilizes the root structure of mushrooms combined with agricultural waste to grow custom-molded, highly protective, home-compostable cushioning (the premier replacement for expanded polystyrene/Styrofoam).

• Mogu / Biohm: European-based innovators focusing on mycelium-based acoustic panels, insulation, and circular packaging components.
• The Packaging Tree / Custom Packaging Lane: Custom-molded structural organic packaging grown from agricultural byproducts. Check out options directly via The Packaging Tree Mushroom Packaging.
• Global licensing: While Ecovative Design originally pioneered much of the foundational "Mushroom Packaging" technology, they now license their platform globally to regional manufacturers who grow the material locally to cut down on shipping footprints.

Algae & Seaweed Packaging Suppliers

Algae-based packaging utilizes rapidly renewable seaweed to create flexible films, transparent wrappers, sachets, and rigid paper coatings that break down naturally in weeks.

• Notpla: Famous for their Earthshot Prize-winning seaweed-based materials. They produce flexible films, pipettes, and bubble-like liquid packaging ("Ooho"), as well as takeaway boxes lined with a 100% natural seaweed coating that biodegrades like a piece of fruit. Explore their capabilities on the Notpla Official Website.
• Kelpi: Based in the UK, they engineer high-performance bioplastics and ultra-thin barrier coatings derived from sustainably farmed seaweed. Their materials are designed to coat paper, card, or molded fiber to replace single-use plastics in food, drink, and cosmetics. Learn more at Kelpi Seaweed Packaging.
• Zerocircle: Creates marine-safe, bio-based alternatives from seaweed, specializing in soluble films, grease-proof wrappers, and tree-free paper coatings.

To help narrow down the right supplier, could you tell me:

• What specific type of packaging you need (e.g., molded inserts for shipping boxes, flexible film wrappers, or food containers)?
• What is your estimated volume or order scale?

Yes. There are several commercial suppliers using mycelium (mushroom roots) or algae/seaweed to replace conventional plastic packaging.

Mushroom / mycelium packaging

• Ecovative / Mushroom® Packaging — One of the strongest options if you need custom molded protective packaging. Their material uses mycelium and hemp hurd and is designed to replace EPS/foam packaging. They offer custom design, prototyping, and regional licensees.
• Magical Mushroom Company — Industrial-scale manufacturer serving Europe/UK. They make molded mycelium packaging from agricultural byproducts and position it as a replacement for expanded polystyrene.
• GROWN bio — Particularly interesting for custom industrial protective packaging. They offer custom molding, prototyping, and production, with standard and custom options depending on volume.
• Hyphae Packaging — A smaller U.S. supplier producing custom mycelium inserts from mycelium, water, flour, and sawdust. They specifically target cosmetics, electronics, automotive components, and other products requiring protective inserts.

Algae / seaweed packaging

• Notpla — One of the better-known commercial seaweed packaging companies. Its seaweed-coated packaging is aimed particularly at food and takeaway packaging, replacing plastic-lined paper and plastic containers.
• Origin by Ocean — Uses brown algae/seaweed as a raw material for bio-based materials and says its products can be made into biodegradable packaging solutions and fibers. This is more of a materials supplier/technology platform than an off-the-shelf packaging manufacturer.
• SeaSol Technologies — Developing seaweed-based packaging intended to replace plastic-lined papers, with an emphasis on food packaging.

My recommendation

If you're looking for a supplier you can actually approach for a packaging project, I'd start with:

1. Mushroom® Packaging/Ecovative — best for molded protective inserts, shipping protection, foam replacement.
2. GROWN bio — good option for European/industrial custom packaging.
3. Magical Mushroom Company — strong choice for larger-scale European manufacturing.
4. Notpla — best fit if you're talking about food containers, trays, takeaway packaging, or plastic-coated paper replacement.
5. Origin by Ocean — worth contacting if you're looking for the raw algae-based material/technology rather than finished packaging.

If you tell me what you're packaging (food, cosmetics, electronics, bottles, shipping products, etc.), approximate annual quantity, and whether you need the supplier in the U.S., I can narrow this down to 3–5 suppliers that are actually suitable for your application and compare MOQ, material, compostability, customization, and likely cost.

Exploring bio-based packaging alternatives to plastic reveals several pioneering suppliers specializing in algae (seaweed) and mushroom mycelium.

Algae & Seaweed-Based Packaging Suppliers

• Notpla: A prominent innovator specializing in natural, seaweed-derived materials. Their portfolio includes flexible films, takeaway food boxes coated with seaweed-based barriers (replacing traditional plastic linings), seaweed paper, and Ooho (edible/biodegradable liquid bubbles). You can explore their offerings directly on the Notpla Official Website.
• Sway: Known for creating seaweed-based, thin-film polybags that function like traditional plastic packaging but are entirely compostable. Their materials are integrated by various sustainable distributors, and their product lines can be found via partners like EcoEnclose Sway Polybag.

Mushroom (Mycelium) Packaging Suppliers

• Mushroom Packaging (by Ecovative): Utilizing mycelium (the root structure of mushrooms) combined with agricultural byproducts like hemp or corn stover, they grow custom-molded, heavy-duty protective packaging. It serves as a direct, home-compostable replacement for expanded polystyrene (Styrofoam) and rigid plastics. You can review their design parameters and inquiry process at Mushroom Packaging.

To help narrow down the ideal supplier, could you share:

• What type of product you are packaging (e.g., liquids, dry goods, fragile electronics, apparel)?
• Whether you need flexible film/wraps or rigid molded/protective inserts?

Yes. There are several credible suppliers in this space, but algae/seaweed and mushroom/mycelium tend to serve different packaging needs.

Strong suppliers to investigate

A particularly interesting option is Mushroom® Packaging. Its material uses mycelium—the root-like structure of mushrooms—to bind agricultural feedstock, and it is intended as a replacement for petroleum-based protective foams. The company offers custom design and prototyping.

For algae, Origin by Ocean is worth contacting if you're looking for a material supplier rather than finished packaging. It produces materials from brown algae that can be incorporated into biodegradable packaging solutions. Origin by Ocean SargasFoam is also interesting because it supplies engineered sargassum-derived foams, pellets, binders and coating additives directly to packaging manufacturers.

One important distinction

If you're trying to replace a plastic bag, pouch, film, bottle, or food package, I'd concentrate on algae/seaweed suppliers.

If you're trying to replace Styrofoam/EPS, molded plastic inserts, cushioning, corner protection, or shipping foam, I'd concentrate on mycelium suppliers.

If you tell me what you're packaging, approximate dimensions, annual quantity/MOQ, and whether it needs to be food-contact safe, I can narrow this to 5–10 suppliers that are actually suitable and commercially available, including U.S. suppliers and estimated pricing/MOQs.

Ecovative (Mushroom Packaging) and Notpla (Algae/Seaweed Packaging) are leading suppliers of bio-based plastic alternatives.
