Paper-based packaging is poised to become a leading force in the European packaging industry by 2030, according to a recent expert study led by Heidelberg in collaboration with DHBW Heilbronn. The study, titled “The Future of Packaging 2030,” projects that flexible paper packaging will experience annual growth exceeding 4.5% throughout the decade, fueled by increasing regulatory pressure, environmental awareness, and changing consumer behavior.

This shift reflects a broader industry movement known as paperization — the replacement of plastic with paper in packaging applications. “It’s not just a trend, it’s a systemic change,” explains Professor Carsten Kortum, the study’s lead researcher and head of DHBW’s Business Administration – Management in Commerce program. According to Kortum, this change is being driven by the EU’s new Packaging and Packaging Waste Regulation (PPWR), which imposes strict guidelines aimed at achieving sustainability and promoting the circular economy.

The PPWR acts as a regulatory catalyst, targeting the phase-out of certain single-use plastics, mandating recycled content, and enforcing standardized recycling symbols. These legislative pressures are compelling businesses to pivot toward more sustainable alternatives like fiber-based packaging. However, industry stakeholders also cite the need for transparent standards and economic incentives to navigate the regulatory shift effectively.

Despite its sustainability advantages, paper packaging faces significant technical and economic hurdles. Fiber-based materials often fall short of the barrier functions required for packaging food, beverages, cosmetics, and non-food items — failing to adequately protect against moisture, oxygen, and grease. In many cases, hybrid materials or functional coatings are needed to address these limitations, which may still compromise recyclability and sustainability goals.

Cost is another concern. Plastic packaging remains cheaper to produce than paper-based alternatives, and consumers are often reluctant to pay more for eco-friendly options. Overcoming this resistance requires innovations that improve both performance and affordability. This is where Heidelberg’s partnership with Solenis, a specialty chemicals manufacturer, becomes particularly relevant.

The two companies are developing a cost-effective barrier coating technology for fiber-based packaging, integrating it directly into the existing flexographic printing process using Heidelberg’s Boardmaster press. This approach allows barrier coatings to be applied inline with high precision, improving both efficiency and material performance. “Our collaboration with Solenis aims to synchronize all aspects — from chemical composition to printing technology — ensuring scalable and sustainable packaging solutions,” notes Dr. David Schmedding, Heidelberg’s CTO and CSO.

These innovations are critical for the broader adoption of paper packaging in mainstream applications. The development of inline coating technologies not only enhances functionality but also positions Heidelberg as a systems integrator in the growing market for folding cartons and other paper-based packaging solutions. As Dr. Schmedding highlights, such initiatives mark Heidelberg’s leadership in advancing the “paperization” movement.

In summary, the path toward replacing plastic with paper in packaging is increasingly viable, thanks to technological advancements and supportive regulations. However, addressing cost, barrier performance, and recyclability remains essential. Through strategic collaborations and a focus on integrated solutions, Heidelberg is at the forefront of redefining the future of packaging in Europe and beyond.
