Pankaboard is reintroducing its main cartonboard grades PankaBrite and PankaWhite with clearly improved product features and performance. Over the past year the company has made substancial efforts and investments in order to bring forward the overall product quality of its major packaging grades. As a result of this determined work Pankaboard is now proudly presenting cartonboard grades, which are bulkier, stronger, optically whiter and which are remarkably improved in terms of sensoric properties. In its production Pankaboard combines sustainable forest management with high ecological and environmental values.
Throughout the entire range of PankaBrite (GC2) the thickness of the board has been increased by 30 microns. For PankaWhite (GC1) the increasehas been 10 microns. This has improved the CD bending stiffness of PankaBrite by up to 3 %, bringing the stiffness ratio of the board closer to the optimum. This improvement will have a direct impact on ready-made packaging. It helps to protect the contents better than before. It also guarantees, that cartons will stay in better shape.
The increase in the product thickness has been achieved by optimizing process conditions and the quality of the ground-wood pulp, which is used for the middle-layer of the boards.
Development in the quality of the ground-wood pulp has, at the same time with increased bulk level, also enabled remarkable quality improvements regarding the visual and surface characteristics of PankaBrite and PankaWhite. More constant surface smoothness and appearance enables immaculate print reproduction in both offset and flexo printing.
