Thorlabs Sweden has adopted Stora Enso’s Papira biodegradable, wood-based cellulose foam for packing its optical and electronic equipment.

Emballageteknik contributed its experience in packaging to tailor Papira into a solution suitable for precision products to replace traditional fossil-based foams.

The design process aimed to deliver shock protection and ensure clean handling and consistent equipment performance.

Thorlabs Sweden development manager Olle Rosenqvist said: “For us, protection and cleanliness are critical. Papira has proven that a bio-based material can meet our technical requirements while supporting our sustainability ambitions.”

Stora Enso said that the project demonstrates that environmental considerations can be incorporated into high-performance packaging.

The partners report that this packaging has met requirements for industrial use, particularly in electronics and optics sectors where protective packaging is essential.

Emballageteknik's sustainability and quality manager Lucas Pontén commented: “This project shows what’s possible when material innovation and converting expertise come together. Papira performs well as shock protection and is a good bio-based alternative to traditional foam solutions.”

Papira is a recyclable material aimed at reducing plastics and waste in packaging.

In December 2025, Stora Enso collaborated with Krekelberg Flock Products and Flocktechniek – C&B Innovations to create a flocked version of Papira, turning the material into a 3D substrate with a velvet-like surface.

Last July, Stora Enso partnered with German water jet cutting company Novapor for a pilot project using Papira. At the time, Novapor said it was identifying clients where the solution suits both practical and branding purposes.
