Trayforma Brown and reduces the basis weight across the Trayforma range – Stora Enso
Stora Enso is presenting two significant developments to its Trayforma tray board range: a reduction in basis weight across the existing range, and the launch of Trayforma Brown, an entirely new unbleached product.
Together, they extend what it demonstrates by improving material efficiency and offering a new option for brands pursuing a natural look on shelf.
The latest lighter has the same strength, forming performance, and converting reliability as the current base board, but utilizes less raw material. Less material per tray indicates better yield throughout the value chain, and a lighter board weight naturally contributes to reduced carbon footprint in production and transport.
Trayforma Range
It responds to demand for a premium natural appearance in tray packaging. Its technical performance meets the exacting demands of 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.
“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,” says Jaana Tani, Technical Account Manager, Trayforma.
Both products are built on a three-ply structure with CTMP in the middle layer, enabling reduced basis weight while maintaining board thickness. Trayforma Brown is well-suited for ready meals, bakery, and chilled and frozen food.
