PaperShell raises SEK 50M to scale biogenic composite materials

PaperShell Raises SEK 50 Million

Swedish biomaterials startup PaperShell has raised SEK 50 million in an undisclosed funding round, the company announced on October 2, 2026. No lead investor was disclosed, and the round did not list any participating investors.

Founded in 2019 and headquartered in Sweden, PaperShell produces patented, load-bearing composite components made from 100% biogenic kraft paper. The company's materials are designed to replace carbon-intensive materials such as plastics, aluminium, and glass-fibre composites.

Technology and Product

PaperShell's core innovation is a process that presses kraft paper into composite components capable of bearing loads. According to the company, its materials are:

• Lighter than metals: Offering weight advantages for applications where mass matters.
• Versatile like fibre composites: Providing design flexibility comparable to traditional composites.
• Fossil-carbon-free: Made from 100% biogenic feedstock.
• Circular: Designed with end-of-life considerations in mind.

The company operates production facilities in Tibro, Sweden, and focuses on scalable automated manufacturing processes to enable volume production.

Target Markets

PaperShell's materials target a range of industries, including:

• Construction
• Transport
• Furniture
• Consumer goods
• Electronics
• Defence

These sectors are traditionally reliant on materials with significant carbon footprints, making them potential adopters of bio-based alternatives as sustainability requirements tighten.

Funding Details

The SEK 50 million round is classified as undisclosed in terms of round type. No lead investor or additional investors were named. The funding date is October 2, 2026.

Strategic Implications

The raise provides capital for PaperShell to scale its automated manufacturing and commercialize its patented composite technology. The company's focus on replacing plastics, aluminium, and glass-fibre composites positions it in the growing market for sustainable industrial materials.

Acquisition Relevance

For acquirers in advanced materials, industrial manufacturing, or sustainability-focused portfolios, PaperShell offers a differentiated technology platform with patented IP and existing production capacity in Sweden. The company's ability to press kraft paper into load-bearing components addresses a specific gap in the bio-composites space, where many alternatives struggle with structural performance. Potential strategic buyers could include materials suppliers, manufacturers seeking to decarbonize their product lines, or defence and transport contractors looking for lightweight, non-fossil alternatives. The undisclosed nature of the round may indicate a strategic or bridge financing, which could signal openness to acquisition discussions as the company scales.
