Sustainable Barrier Alternatives and Applications with Stora Enso

Surface treatment methods
Recyclable packaging
Advanced materials


Renewable materials











Stora Enso, a leader in renewable materials, is developing new generations of bio-based and renewable food packaging solutions and is constantly working on sustainable and recyclable packaging options for a range of industries and applications worldwide. Now, we are looking for novel barrier application technologies and applications to treat our fiber-based cardboard to create even more eco-friendly barrier solutions.

Opportunity overview

The Packaging Materials division at Stora Enso is driven by a high demand for plastic free and eco-friendly circular packaging. Our ultimate goal is a reduction in CO2 emissions by decreasing plastic use and increasing recyclability, which is currently done by providing premium renewable and recyclable packaging materials based on both virgin and recycled fiber. However, cardboard and paper materials are still mostly coated with plastics to provide functionality and required barrier properties.

We are searching for innovative solutions to make our packaging fully recyclable and equip cardboard and paper materials with protective features. This can be either in the form of alternative barrier materials (to reduce the amount of plastic while achieving equivalent barrier properties) or through implementing a new base material and/or application technologies.

The materials should eventually comply with food-grade standards, endure humidity and provide a longer shelf life without compromising high barrier properties. As most of the product segments require specialized or customized barrier properties in areas such as various foods, cosmetics and pharma, Stora Enso has a variety of use cases and therefore requirements for materials also vary based on the packaging type.

Your opportunity with Stora Enso

We want to replace non-renewable barriers with recyclable and biodegradable solutions. Now we are looking to utilize innovative materials and state-of-the-art technologies, that would be processable and scalable in our production lines. We are open for further co-development to accelerate the growth of your solution. We are looking to collaborate and share our industry & commercial knowledge to provide you with valuable information about our manufacturing process and commercialization possibilities, enabling your company further opportunities within the industry.

Focus Areas

Examples of solutions we’re interested in

Optimization of existing barrier applications

As we’re already working with a wide range of barrier materials and technologies, we are interested in novel ways to optimize the existing processes and applications.

Novel barrier materials applied on existing technologies

We are looking for novel renewable high-performance (OTR < 0.5 and/or WVTR<0.5) barrier materials that can be applied with the common technologies, for example extrusion and dispersion.

Novel application technologies and materials

We are also investigating new technologies, processes, application methods or surface treatment concepts to construct barrier properties for existing substrates. We are hoping to find “out-of-the-box” approaches and methods not commonly used in the paper and board industry.
