The search for sustainable alternatives in beauty packaging is driving innovation in materials forward. One of the most promising solutions is biocomposites, which are engineered materials that combine natural fibres, such as wood, hemp or cork, with bio-based or recycled polymers.
The result is a material that offers the mechanical strength of composites while reducing reliance on virgin plastics. For beauty brands, biocomposites offer a means of integrating sustainability directly into product design, creating components that are durable and align with consumers' expectations of eco-conscious beauty products.
A biocomposite is a material created by reinforcing a polymer matrix with natural fibres or fillers. In practice, this involves combining renewable resources, such as wood fibers, cork granules, hemp and flax, with bio-based or recycled polymers to create a new material with enhanced properties.
So, the most important things to remember are:
The appeal of biocomposites lies in their balance. They can reduce weight, increase the strength-to-density ratio and improve sustainability by reducing reliance on virgin plastics. At the same time, they offer unique aesthetic qualities, such as natural textures and visible grain, or even customisable colour effects.

Biocomposites combine the strength of natural fibres with the versatility of polymers, providing brands with a premium-feeling material that reduces environmental impact. They are lighter than many traditional plastics and pleasant to the touch. They can also be finished with unique textures or colours that highlight their natural origin.
However, these materials also present specific challenges. For example, natural fibres absorb moisture, which can affect dimensional stability, and some bio-polymers have a narrower processing window than conventional plastics. Achieving consistent colour and surface finish also requires careful control.
The good news is that these limitations can be overcome through design and engineering. With the right treatments, compatibilizers and production expertise, biocomposites can provide reliable closures and inserts that meet the technical requirements of beauty packaging, offering a distinctive, sustainable character.
In the world of beauty packaging, biocomposites are creating a new space where technical performance meets sustainable storytelling. They are already being used in various ways:
At Minelli, innovation is always rooted in materials. Through mPackting, the division dedicated to sustainable beauty packaging, we have translated the principles of biocomposite technology into solutions tailored for cosmetics.
mBlack™ is the most representative example. This proprietary biocomposite combines biochar derived from wood with a bio-based matrix, creating a material that is OK Biobased and OK Biodegradable (TÜV Austria certified). The result is a surface with a deep matte aesthetic and velvety touch, designed to communicate luxury and responsibility.
Unlike generic biocomposites, which are often developed for industrial or technical uses, Minelli’s biocomposites are engineered for premium applications. With mPackting, beauty brands can rely on materials that combine:
Through this material innovation, mPackting redefines biocomposites as a strategic resource for beauty packaging, turning eco-conscious materials into distinctive brand assets.
At Minelli, we believe that materials shape perception. With mPackting, we transform biocomposites into premium components that combine aesthetics, performance and ecological responsibility.
Whether you are developing a new fragrance, a skincare line or a refillable collection, our integrated expertise enables us to co-design, prototype, and produce with purpose.
