Ranheim Paper & Board AS

Coreboard

All production of coreboard in Ranheim is based on recycled paper from Norwegian and Swedish collection companies. The long fibres provide a quality well suited for production of high-performance coreboard, and Ranheim Paper & Board offers grades from 300 to 1200 J/m² ply bond (delamination strength). The product range called RT 300-RT 1200 is used for paper mills, film and textile cores.

Added value on core winders

Ranheim was among the first mills in the world to produce a coreboard with Ply Bond strength 1000 J/m², and since the early 1990s, Ranheim has produced this grade on a regular basis. There are only a handful of mills in the world able to make such strong coreboard and Ranheim has for many years been the only independent of these mills, not being integrated in core production and consequently not competing with its customers.

Coreboard from Ranheim is well known for good runnability and added value on core winders. The mill is very flexible in terms of customizing specifications to customers’ requests, e.g. thickness/bulk, glue absorption etc.
