Mondi equips Swiss Krono with breathable kraft paper to wrap heavy laminate flooring

Breaking the plastic dependency in heavy-duty industrial packaging

For years, the industrial consensus dictated that heavy, sharp-edged products like laminate flooring required the high puncture resistance and load stability of plastic stretch and shrink films. In 2026, that assumption is being dismantled on the factory floor. In a significant technical partnership, sustainable packaging leader Mondi has collaborated with Swiss Krono to fully transition the latter’s German flooring operations to paper-based packaging, utilizing advanced kraft paper grammages that meet rigorous physical distribution demands.

The move is a powerful signal to the broader corrugated, paper, and converting industry: high-performance paper is no longer restricted to lightweight consumer goods or e-commerce mailers. It can handle the harsh physical realities of industrial transport while delivering simultaneous gains in production line efficiency and material circularity. As manufacturers face mounting pressure to reduce scope 3 emissions, this case study proves that the structural integrity of specialized kraft paper is up to the task.

Optimizing automated lines with targeted kraft solutions

To replace polyethylene films without compromising line speeds or throughput, the companies integrated two highly engineered Mondi paper grades into the existing manufacturing workflow. For the primary packaging of trays containing 10 laminate panels, Swiss Krono deployed Eco/Vantage Kraft Pro. Applied using automated Hugo Beck packaging machinery, this specific grade incorporates 20% recycled content and offers exceptional puncture resistance, a critical physical property needed to protect the heavy, sharp edges of the wooden boards during stacking and transit.

Beyond the obvious material substitution, the operational benefits achieved on the production line are striking. The switch from plastic shrink film to paper allowed Swiss Krono to completely decommission their energy-intensive heat-shrink tunnels. In an era where energy costs remain a critical variable for manufacturing profitability, removing a thermal process step yields immediate financial and environmental dividends. Furthermore, the excellent printability of the kraft paper enables the direct printing of branding, safety icons, and user instructions on the exterior wrapper, eliminating the need for separate paper inserts that were previously required inside the plastic film.

For the secondary packaging stage, Swiss Krono adopted Ad/Vantage StretchWrap to secure heavy palletized loads. This 70 gsm, 100% virgin kraft paper contains zero plastic coatings or laminations. It is applied via dedicated secondary wrapping machinery from PaperWrap. The material delivers the high stretchability and tear resistance necessary to keep heavy wood pallets stable during long-haul transit, while ensuring the entire packaging stream remains fully recyclable in standard European paper waste systems.

A surprising logistical win for the end-user

While the reduction in CO2e emissions—verified by Mondi’s internal product impact assessments—and the transition to a circular material align perfectly with current 2026 sustainability goals, the most fascinating aspect of this project is its downstream impact on the customer experience. Wood-based panels wrapped in impermeable plastic traditionally require a strict 24-hour acclimatization period upon delivery to adjust to the ambient humidity and temperature of the room before installation can begin.

Because Mondi’s engineered kraft paper is naturally breathable, it allows the flooring panels to acclimatize passively during the logistical transit phase. Professional installers can now lay the laminate flooring immediately upon delivery. In the fast-paced construction and interior design sector, where time directly equates to labor costs, this unlocks a massive operational advantage, transforming the packaging from a mere protective layer into a true value-adding feature.

This collaboration perfectly illustrates how smart material substitution can solve operational bottlenecks that go far beyond basic environmental compliance. By thinking holistically about the product's entire lifecycle—from the removal of energy-heavy shrink tunnels in the factory to the elimination of waiting times on the job site—Mondi and Swiss Krono have set a new commercial benchmark. Will we soon see other heavy building materials, such as ceramic tiles, architectural panels, or modular furniture, adopting breathable paper wrappers to unlock similar efficiencies on the installation front?
