Viktor Siewertz joins PulPac from IRLAB Therapeutics AB, listed on Nasdaq Stockholm Main Market.

SWEDEN – Swedish packaging innovator PulPac has appointed Viktor Siewertz as its new Chief Financial Officer, effective September 1, 2025.
Siewertz brings extensive experience from his previous role as CFO at IRLAB Therapeutics AB, a company listed on Nasdaq Stockholm Main Market, where he served since 2017.
His career also spans leadership roles in mergers and acquisitions, financial advisory, and business development across various sectors.
In a statement, PulPac’s CEO, Linus Larsson Green, said about the appointment, “We are very pleased to welcome Viktor to PulPac.”
“His deep knowledge of capital markets and financing will strengthen our leadership team as we continue to scale Dry Molded Fiber globally.”

Siewertz himself expressed excitement about joining PulPac, noting the company’s clear mission and strong potential to advance sustainable packaging.

The company also secured a US$33 million investment in 2022 from a cross-industrial alliance, including Aliaxis and Stora Enso, to scale its technology globally.
With Siewertz’s financial expertise, PulPac aims to further its mission of replacing single-use plastics with cost-competitive, sustainable alternatives, contributing to a circular economy in the packaging industry.
