Holmen INNR is an interliner paper, produced with fresh fibres in a highly efficient thermomechanical pulping process, TMP, where nothing from the pulp goes to waste. The result is a paper which is light and strong, 100 percent recyclable and 100 percent repulpable. It's as cost-efficient as it's sustainable, thanks to the production process and the low transportation weight.
Complement to liner and fluting
The interliner, sometimes called the midliner, is a containerboard component that stabilizes the intermediate layers. It's a complement to the corrugated layers (fluting) and the liner. Holmen INNR is typically used for the second single facer station in the corrugated board production process. There it is adhered directly to the fluted medium from the first facer station. Making up the innermost layer in double or triple wall boards, interliner is used for boxes that are light, yet strong.
Low weight, smooth surface
Holmen INNR is sturdy for its weight. The mechanical separation of the wood fibres make them keep their relative stiffness and elasticity. This means you can get a stable result and still have the advantage of a low basis weight. With its smooth and even surface, the paper runs well through containerboard and paper converting machines. As it's uncoated, it also reacts well to the gluing process. Holmen INNR is a base paper with great potential.
