Metsä Group commits €25 million to scale direct-to-shape molded fiber packaging in Finland

Moving from demonstration to commercial scale

Metsä Group has committed €25 million to scale its Muoto molded fiber packaging technology, moving decisively from the demonstration phase to full commercial production. The new manufacturing line will be integrated into the company’s Äänekoski bioproduct mill in Finland, with commercial operations slated to begin in 2028.

This capital expenditure by @MetsäGroup represents a critical step in the commercialization of next-generation fiber products. The planned facility will boast a nominal capacity of over 100 million units annually. The primary target for this output is the demanding food packaging sector, specifically applications like takeaway trays, fresh produce containers, and ready-meal packaging—segments that have historically relied heavily on thermoformed plastics.

The technical advantage of direct-to-shape manufacturing

What makes the Muoto process technically significant is its direct-to-shape manufacturing methodology. Developed through a strategic partnership with Valmet, the technology bypasses traditional intermediate steps. Instead of drying the pulp into market bales and re-pulping it at a converting facility, the Muoto process molds the packaging directly from wet wood pulp on-site.

This integrated approach not only reduces energy consumption and water usage but also yields a product that offers an exceptional strength-to-weight ratio. The resulting material provides the high rigidity required for food-contact applications without unnecessary bulk, solving one of the main structural challenges of traditional molded pulp.

Capex optimization and regulatory tailwinds

Interestingly, Metsä pivoted on the final location for this investment. While pre-engineering studies conducted in 2024 initially pointed to the Rauma mill as the likely site, the company ultimately opted for Äänekoski. This decision is a classic example of capex optimization. By co-locating the commercial line with the existing Muoto demonstration plant and the broader Äänekoski bioproduct infrastructure, Metsä minimizes logistical friction, leverages existing technical expertise, and significantly lowers the overall investment threshold.

The regulatory tailwinds driving this investment are undeniable in the current 2026 market landscape. As the European Union enforces the stringent mandates of the recently updated Packaging and Packaging Waste Regulation (PPWR), fast-moving consumer goods (FMCG) brands are under immense pressure to transition away from fossil-based polymers. The PPWR's strict recyclability and plastic-reduction targets have created a massive demand vacuum for high-performance fiber alternatives.

Niklas von Weymarn, CEO of Metsä Spring, the group's innovation arm, rightly points out that this legislative pressure creates a significant commercial niche. The ability to offer a fossil-free, fully recyclable 3D packaging solution that does not compromise on structural integrity positions Metsä to capture premium margins in a rapidly shifting regulatory environment.

The broader implications for the packaging supply chain are substantial. As we navigate through 2026, the molded fiber sector is evolving from basic egg cartons to highly engineered, precision-molded geometries. Metsä's €25 million commitment signals to the market that the technology is mature enough for high-volume, continuous production. Furthermore, the reliance on northern wood fibers ensures a sustainable, traceable raw material source, which is increasingly demanded by global retailers aiming to clean up their Scope 3 emissions.

The transition from wet pulp directly to a finished 3D product at a 100-million-unit scale proves that the industry is finally cracking the code on cost-effective plastic substitution. Will the operational efficiencies gained at the Äänekoski site be enough to make Muoto price-competitive with legacy plastics in the highly margin-sensitive food service sector?
