Stora Enso\u202fhas updated its Trayforma portfolio by introducing\u202fthe new unbleached Trayforma Brown and cutting basis weights across the range.<\/p>\n

The lighter Trayforma maintains the same strength, forming characteristics and converting performance as the current board while requiring less raw material.<\/p>\n

The company added that lower material use per tray can raise yield across the value chain while reduced board weight may help cut the carbon footprint linked to production and transport.<\/p>\n

Trayforma Brown has been added as an option for tray packaging with a natural-looking finish.<\/p>\n

The product meets the same technical requirements as other Trayforma grades. Stora Enso describes it as the first brown tray board designed for oven heating, enduring temperatures of up to 220\u00b0C when used with a transparent PET coating.<\/p>\n

The grade is also offered with a high-barrier BarrPeel option for vacuum-skin packaging.<\/p>\n

Both products use a three-ply construction with CTMP in the middle layer.<\/p>\n

According to the company, this structure allows the basis weight to be reduced without decreasing board thickness.<\/p>\n

Trayforma Brown is suitable for ready meals, bakery products, and chilled and frozen foods.<\/p>\n

Trayforma technical account manager Jaana Tani said: \u201cFor our customers, the natural look of brown board is increasingly relevant, but not at the cost of performance. <\/p>\n

\u201cWith Trayforma Brown, they don\u2019t have to make that trade-off. And with our advancements in lightweighting Trayforma, everyone in the value chain benefits from better yield.\u201d<\/p>\n

Earlier this month, Austria\u2019s\u00a0Dunapack\u00a0Packaging\u00a0agreed to acquire<\/a>\u00a0Stora Enso\u2019s corrugated packaging operations in Germany.\u00a0<\/p>\n
