As companies look for ways to reduce conventional plastic packaging and introduce more sustainable materials, protective packaging is becoming an important area for improvement.
EPS foam, EPE foam, EVA cushioning, and other plastic-based protective materials have been widely used for decades because they are lightweight, cost-effective, and provide reliable protection. However, they can also create challenges for businesses working toward plastic reduction, ESG targets, and more sustainable packaging strategies.
For suitable applications, mycelium packaging provides a bio-based alternative.
YiTo Pack develops custom mycelium packaging made from fungal mycelium and natural plant fibers. It can be molded into inserts, trays, holders, corner protectors, end caps, and other protective structures according to different product requirements.
From structural development and rapid prototyping to testing support and batch production, YiTo Pack helps customers turn sustainable packaging concepts into practical packaging solutions.
What Is Mycelium Packaging?
Mycelium is the root-like network of fungi. In mycelium packaging production, this natural network acts as a binder that connects plant-based materials such as:
- · Agricultural residues
- · Wood particles or sawdust
- · Forestry by-products
- · Other natural fibers
These materials are placed into a mold and grown under controlled conditions. As the mycelium develops, it binds the fibers together and forms a three-dimensional structure.
After the required shape has formed, the material is dried and stabilized to create the finished packaging component.
Plant Fibers + Mycelium → Molded Bio-Based Protective Packaging
This production method allows packaging manufacturers to create custom structures without relying entirely on conventional fossil-based foam materials.
Why Are Companies Exploring Mycelium Packaging?
1. Reducing Conventional Plastic Foam
One of the main reasons companies explore mycelium packaging is to reduce their dependence on fossil-based protective materials.
Traditional EPS foam performs well in many applications, but collection and recycling infrastructure varies significantly between markets.
For brands with plastic-reduction, sustainable procurement, or ESG goals, replacing selected foam components with bio-based materials can become part of a broader packaging strategy.
Mycelium packaging provides an alternative based primarily on fungal mycelium and natural plant fibers.
Depending on the complete formulation, treatment, and disposal conditions, the finished product may also offer biodegradation benefits. Environmental claims should always be supported by testing applicable to the specific finished product.
2. Providing Protective Performance
Sustainable packaging still needs to perform its most important function: protecting the product.
The naturally porous three-dimensional structure of mycelium materials can be designed to provide:
· Cushioning protection
· Impact absorption
· Product positioning and retention
· Compression resistance
· Structural support
Density, thickness, geometry, cavities, and supporting points can all be adjusted according to the product and transportation requirements.
Because packaging requirements vary, final performance should be evaluated based on the actual application.
Depending on the project, testing may include:
· Drop testing
· Vibration testing
· Compression testing
· Product-fit testing
· Moisture evaluation
· Storage testing
Mycelium packaging should therefore be considered a project-specific protective packaging solution rather than a universal replacement for every type of foam packaging.
3. Creating Custom Packaging Structures
-
Standard foam inserts often fail to fit unusual shapes, fragile areas, or premium presentation needs. That's why custom mycelium packaging can be designed around:Product dimensions, weight, and shape
- ·Fragile areas and support points
- ·Outer-box dimensions and transport needs
- ·Target market and required protection
Available formats include molded inserts, protective trays, bottle holders, corner protectors, cushioning end caps, product holders, packaging boxes, and irregular protective structures.
This lets the packaging fit the actual product—no more piecing together generic cushioning materials.

FAQ
Q1：Is mycelium packaging biodegradable?
Mycelium packaging may biodegrade under specified conditions depending on its complete formulation and treatment. Any biodegradability claim should be supported by relevant finished-product testing.
Q2：Can mycelium packaging completely replace EPS foam?
Not in every application. Its suitability depends on product weight, fragility, packaging design, transportation conditions, moisture exposure, and required protective performance.
Q3:Can the shape and size be customized?
Yes. Inserts, trays, holders, corner protectors, end caps, and other molded structures can be developed according to specific product requirements.
Q4:Is mycelium packaging suitable for food contact?
Food-contact suitability should not be assumed simply because the material is naturally derived. The finished product should be evaluated according to the applicable food-contact requirements of the intended market.
