CKB gets a sleek sustainable top liner

Stora Enso's CKB 195 g/m2 board was developed for use as a top liner for corrugated materials, boxes and displays. The new 195 g/m2 grade is ideal in combination with other materials because of its sleek surface and high efficiency in converting processes. And Stora Enso has lightweighted the entire range this year.

It is exceptionally strong and crack resistant and is stable during gluing. Its high bulk provides a sleek surface, which helps to avoid the washboard effect when laminated on top of fluting materials.

CKB is a multilayer kraft back board and the preferred packaging board for many wine, beer and beverage brand owners, who use it in cartons and multipacks. A creative designer can use the brown back of the board to achieve a natural look and feel. Stora Enso offers CKB with several special coating options, which increase the designer's choices. It offers excellent protection of goods, logistics efficiency and branding power, and is known for its excellent runnability in printing and converting processes.

The CKB range is now 175 to 380 g/m2, so CKB is more sustainable because it takes less raw material to produce. Capacity increases at Stora Enso's Skoghall Mill in Sweden have made CKB more readily available too.

"We have high expectations for CKB to take a bigger market share as a top liner, as the board is now more sustainable and competitive thanks to its lower weight," stated Öystein Aksnes, Stora Enso's general packaging segment director.
