Walki Experts video:  Fibre-based secondary packaging

What are the primary benefits of switching from plastic-based to fibre-based materials for secondary packaging?

The primary benefits of transitioning from plastic-based to fibre-based materials for secondary packaging include improved recyclability, enhanced aesthetic appeal, and adequate strength to securely contain the products. Fibre-based materials, such as paper, not only provide an attractive shelf presence but also help in reducing plastic usage in packaging. Furthermore, brand owners can reduce costs associated with EPR fees and plastic taxes by opting for fibre-based materials.

How do the requirements for secondary packaging differ from those for primary packaging?

Secondary packaging does not need to provide the same barrier functionalities as primary packaging, which protects the food product directly from moisture and vapor. The main mechanical requirement for secondary packaging is that the paper is strong and stable enough to withstand the weight of the individual packages inside. Additionally, ensuring the pouch is well sealed is crucial for keeping the individual products safely inside.

What methods can be used to seal fibre-based secondary packaging, and how do they impact recyclability?

Walki uses two main methods to seal fibre-based secondary packaging: applying a coated paper with a very thin layer of coating over the entire surface, or partially covering the areas where the package is sealed with the sealing medium. The latter method enhances recyclability by using significantly less sealing medium compared to full coverage, making the packaging easier to recycle within the well-established paper waste stream.

Can fibre-based materials be used in high-speed packaging lines without compromising packing speed?

Yes, fibre-based materials can be used in high-speed packaging lines without compromising packing speed. Our secondary flexible packaging solutions become sealable at relatively low temperatures, making them suitable for most packaging lines, including high-speed lines. Contrary to popular belief, the production speed is not slower with fibre-based materials compared to film.

How does Walki address the aesthetic and functional demands of brand owners for secondary packaging?

We addresses the aesthetic and functional demands of brand owners by offering tailored materials that suit customer demands. We provide thin or thick paper, bleached or brown, with enhanced printability to meet high aesthetic standards. We also uses water-based inks and varnishes, supporting sustainability trends. Recent investments in modern printing capacity in our plants in Poland, Finland, and Germany ensure outstanding visual appearance and functionality, helping products stand out on supermarket shelves.

How do Walki’s fibre-based secondary packaging solutions align with the EU Packaging and Packaging Waste Regulations (PPWR), and what benefits do they offer in this context?

Walki’s fibre-based secondary packaging solutions align well with the PPWR by prioritizing recyclability and reducing plastic use. As the main component is wood fibers, the packaging is primarly from renewable resources, and will most of the time provide a significant reduction in CO2-footprint compared to multi- or monolayered plastic laminates. These paper-based solutions ensure easy recycling within established paper waste streams corresponding to future recycling classes mainly Class A. This not only helps in meeting regulatory requirements but also helps brand owners achieve their sustainability objectives throughout the value chain and correspond to consumer preferences.
