STORA Enso has announced it is launching two new developments to its Trayforma tray board range: a basis weight reduction across the existing range, and Trayforma Brown, a new unbleached product.
The new lighter Trayforma is said to deliver the same strength, forming performance, and converting reliability as the current base board, but uses less raw material.
Trayforma Brown, meanwhile, responds to demand for a ‘premium natural appearance’ in tray packaging. Stora Enso explained that its technical performance meets the same demands as the rest of the Trayforma family, and it is the first brown tray board to support oven heating, withstanding temperatures up to 220°C with a transparent PET coating. It is also available with a high-barrier BarrPeel solution for vacuum-skin packaging.
Jaana Tani, technical account manager, Trayforma and Barriers at Stora Enso, said, “For our customers, the natural look of brown board is increasingly relevant, but not at the cost of performance. With Trayforma Brown, they don’t have to make that trade-off. And with our advancements in lightweighting Trayforma, everyone in the value chain benefits from better yield.”
Both products are built on a three-ply structure incorporating CTMP in the middle layer, which enables reduced basis weight while maintaining board thickness. Trayforma Brown is suitable for ready meals, bakery, and chilled and frozen food.
Trayforma Brown and the lightweighted Trayforma range will be presented at Interpack 2026 in Düsseldorf next month.
