End-to-end Molded Fiber Solutions: From Tooling to Production
Packaging is no longer a separate phase of the supply chain — it is a vertically integrated process.
At Prototal, we provide the full infrastructure required to move from initial packaging design to the final packaging product. By managing both a radical new way of producing tools with HP Industrial 3D Printing combined with our own molded fiber lab in Malmö, we eliminate any friction in your supply chain.
A Complete Lifecycle Solution From Concept to Scale
Our end-to-end infrastructure is built on a “Concept to Scale” model that allows us to refine every variable of the production cycle under one roof. By managing the technical nuances in-house, we turn manufacturing complexity into a measurable competitive advantage for our partners.
Material & Recipe Optimization
We don’t just use standard materials; we optimize the “recipe” for your specific application. By refining factors like forming, dewatering, and cycle times, we directly decrease lead times and maximize production line productivity.
Advanced Perforation & Geometry Control
Through high-resolution MJF technology, we achieve precise perforation optimization. This allows for zone-based grammage control and significant weight reduction in final parts. The result is improved mechanical properties and a reduction in both variable costs and material waste.
Utility & Dryness Efficiency
Our process includes dryness optimization to reduce utility consumption. By precisely controlling the moisture-removal phases of production, we achieve significant energy and water savings, making the industrial transition to molded fiber more sustainable and cost-effective.
Accelerated Sample Production
The proximity of our digital tooling to our production lines allows us to shorten the time to prototype down to just 2–3 weeks. This rapid turnaround enables more iterations and ensures a faster, lower-risk introduction of new products to the market.
Enabled by HP Multi Jet Fusion
Our infrastructure leverages proprietary HP technology with special calibrated Multi Jet Fusion (MJF) 3D Printing machines. Tools are produced with biobased PA 11 — a polymer derived from castor oil.
Our calibrated 3D printing machines delivers exceptional resolution, capable of producing complex meshes and ventilation patterns with hole diameters as small as 0.4mm. This precision ensures optimal flow and filtration, reducing fiber and water consumption and providing a technical advantage compared to traditional tooling for molded pulp.
Why consider Molded Fiber with Digital Tooling?
| Variables | Digital Tooling with 3D Printing | Traditional Tooling |
|---|---|---|
| Lead Time | 2-3 weeks | 5-8 weeks |
| Geometries | Complex | Limited |
| Screen | Digital Workflow | Manual Labor |
| Optimization | Digital Topology Optimization | Limited |
| Rapid Iterations | Yes | No |
Lead times may be influenced by the recipe of molded pulp, complexity of digital tooling, perforation patterns, and specific dewatering requirements.
An Integrated Tooling Architecture
This is not just a tool; it is the infrastructure for a circular economy.
In the global shift toward sustainability, the packaging is no longer just a container — it is a brand’s commitment to the future.
By removing the traditional barriers of long lead times and geometric constraints, we enable our partners to transition from plastic to fiber at an industrial scale, turning sustainability from a corporate challenge into a competitive advantage.

Packaging Engineered for Visionaries
High-Volume Food Commodities
In the fast-moving food commodity sector, efficiency and reliability are paramount. We provide the industrial-scale infrastructure necessary for the high-volume production of essential items like egg trays, cartons, and durable cup carriers.
By optimizing recipes and tooling for these specific products, we help producers decrease lead times and increase overall productivity without sacrificing the structural integrity required for high-speed logistics.
Next-Generation Food & Beverage Packaging
The “New Food” market demands packaging that acts as a premium brand ambassador while meeting strict sustainability goals. We enable the production of complex, high-precision items such as lids, cups, food trays, and coffee capsules.
Using our digital tooling and MJF perforation optimization, we achieve the tight tolerances and sophisticated geometries required for these consumer-facing products, turning sustainability into a measurable competitive advantage.
Industrial & Technical Packaging
For the industrial and cosmetic sectors, packaging must provide maximum protection with minimal environmental impact. Our solution enables the creation of custom protective packs and high-end cosmetic inserts that offer superior shock absorption and aesthetic finish.
By utilizing zone-based grammage control and advanced MJF meshes, we reduce part weight and variable costs while ensuring that sensitive electronics or luxury goods remain perfectly secure during transit.
Pulp Recipe Engineering: The Scientific Foundation of Fiber Performance
The success of a molded fiber solution starts with the molecular integrity of the pulp. At our dedicated Molded Fiber Lab in Malmö, we treat fiber composition as a precision-engineered variable, optimizing the blend to meet specific mechanical and aesthetic requirements.
By calibrating the fiber-to-water ratio and additives, we achieve superior recipe optimization that directly enhances forming efficiency and dewatering speed.
Your end-to-end packaging partner
From high-precision digital tooling to industrial-scale material production, Prototal provides the integrated infrastructure for the circular economy. We bridge the gap between concept and delivery, enabling a seamless transition from plastic to fiber with unmatched speed and geometric freedom.

We provide a vertically integrated infrastructure where we manage both the high-precision digital tooling and the final material production in-house. This eliminates the traditional friction between toolmaker and producer, ensuring that the design intent is perfectly reflected in the final part while significantly reducing lead times.
Our Molded Fiber Lab in Malmö serves as the unified heart of our fiber operations, housing our entire end-to-end infrastructure under one roof. Here, we combine advanced material science with industrial-scale additive manufacturing. We conduct exhaustive recipe optimization, calibrating fiber blends and additives to meet precise requirements for moisture resistance and structural integrity.
By housing our HP MJF 3D printing fleet directly alongside our fiber laboratory, we bridge the gap between digital tooling and physical production. This proximity allows our engineers to test 0.4mm perforation patterns against custom pulp recipes in real-time, ensuring that every batch is perfectly optimized for dewatering speed and dimensional accuracy before it reaches the production floor.
By utilizing digital tooling, we can often shorten the time to prototype down to just 2–3 weeks. Final production lead times depend on part geometry, build volume, and the complexity of the pulp recipe developed at our lab.
