At interpack, Kiefel is showcasing a breakthrough in natural fibre packaging: their new double-dip wet molding process.
This innovation enables the creation of grease and oil barriers made entirely from natural fibres, without the need for an additional plastic coating. The technology will be demonstrated live on a KFT Lab machine at booth C57 in hall 8.
“Our new double-dip process elevates fiber packaging by integrating functional barriers directly into the fiber itself - offering an efficient, scalable solution for industrial-scale production,” says Thomas Kreiseder, director product management at Kiefel.
The method expands existing possibilities to make natural fibre packaging more durable whilst recyclable and biodegradable. Common methods include spray coating or additives.
Through a patented, multi-stage manufacturing process featuring an integrated microfibrillated layer, Kiefel’s new technology produces packaging with high-performance grease and oil barriers - an efficient, scalable solution built entirely on renewable raw materials.
Visitors can experience the results firsthand at the Kiefel booth’s test station, where the company will be demonstrating that these barriers remain stable for several weeks, or even months. Typical applications include margarine tubs, takeaway food and similar food packaging.
Fiber technologies working together as a perfect match
This development aligns with Kiefel’s overarching “Perfect Match” approach. The goal is to synchronize technologies and processes to deliver the perfect balance of material, functionality, and cost-effectiveness for every application.
While Wet Fiber excels in complex, deep-drawn packaging with high functional demands, Dry Fiber provides a high-efficiency solution for transforming roll-fed paper and fibers into sleek, dimensionally stable packaging.
Together, both technologies open up new possibilities for FMCG brands and converters – from high-performance individual components to intelligent complete solutions from a single source.
Live at other leading international trade fairs
After Interpack, the solution will also be on display live at other international trade fairs, including Plastpol, Equiplast and Plast Milan.
