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.
For sustainable containerboard
Holmen INNR is a fresh-fibre fluting medium and interliner paper for containerboard. Thanks to the strength of the paper, you can use an interliner in a lower basis weight than your traditional liner paper. It saves cost, since you need to buy less paper, and it saves weight in all transports, also for your customer using the final boxes. And most importantly, using paper in a lower weight will also reduce the total carbon dioxide emissions.
Low weight, smooth surface
Holmen INNR is sturdy for its 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, which makes it the perfect interliner paper. And you can use the same paper for fluting if you like.
By switching to a TMP-produced interliner like Holmen INNR, you will reduce both the weight of your finished board, and its carbon footprint.
Carbon footprint is calculated as kilograms per tonne.
Carbon footprint INNR
Carbon footprint is defined as the total emissions caused by an individual, event, organisation, or product, expressed as carbon dioxide equivalent. Holmen Paper calculates the carbon footprint of our graphical paper products according to the ten toes of the framework set up by CEPI.
