Our History
From paper mill to material science partner
Founded in 1930 in Valkeakoski, Finland, Walki began as a paper mill. Over the decades, we have evolved through bold decisions, technological development and strategic acquisitions into a material science company focused on circularity and low-carbon solutions.
Key milestones include early investments in extrusion coating, international expansion, entry into construction and consumer packaging, and the integration into the Oji Group in 2024, strengthening our global R&D capabilities and footprint.
Our ability to adapt has defined us for nearly a century and continues to guide our future.

Business Areas
Three divisions,
one circular ambition
Rethinking
Consumer Packaging
Packaging is a strategic, value-creating element for brand owners. Walki develops reliable, functional and visually appealing packaging solutions designed for demanding consumer applications. Our portfolio includes flexible packaging for the food industry, covering meat, fish, cheese, dairy, biscuits, dry food and confectionery. We also offer a wide range of films and bags, including bio-waste bags, fruit and vegetable bags, recycled waste bags and compostable films.
All solutions are designed with circularity and PPWR compliance in mind, using recyclable, compostable or renewable materials.
Packaging Materials for a fibre-based future
Walki supports the transition toward easily recyclable, fibre-based packaging solutions for industrial and specialty applications. Whenever possible, our materials are fibre-based to enable efficient recycling. For demanding, high-barrier uses, we develop mono-material solutions that combine performance and recyclability. The portfolio includes barrier boards for frozen food, food-on-the-go and household products, barrier linings for pre-printed liners, liners for fish, fruit and vegetable boxes, as well as reel, industrial and flexible packaging materials.
Engineered Materials for Sustainable Constructions
Walki develops advanced technical materials for construction and other demanding environments where performance and safety are essential. Our solutions are used in membranes, insulation and related applications to improve building energy efficiency and reduce carbon impact. The portfolio focuses on fire-retardant and breathable materials designed for durability, functionality and recyclability, supporting healthier indoor environments and long-term building performance.
Transforming Materials Towards a Circular Future
Our ambition is clear: to advance circularity through durable, recyclable and compostable material solutions.
We prioritise renewable resources, life-cycle thinking and circular-economy principles across our operations. Sustainability and resource efficiency are embedded into product development from the very beginning.
