# Commission Decision of 6 October 2004 declaring a concentration compatible with the common market and the EEA Agreement (Case COMP/M.3431 — Sonoco/Ahlstrom) (notified under document number C(2004) 3678) (Only the English text is authentic) (2005/452/EC), Division (5)

Extent: E+W+S+N.I.

Coreboard is a paper/board material used primarily for manufacturing paper cores. The key characteristic of coreboard is its ability to resist delamination, which is measured in Joules per square meter (J/m2). There is only a limited degree of demand-side and supply-side substitutability. The high-grade (delamination resistance >375 J/m2) producers can easily switch production to low-grade (delamination resistance <375 J/m2), low-grade producers need to make important investments to produce high-grade coreboard. In light of the above, high-grade and low-grade coreboard can be considered to constitute the relevant product markets for coreboard.
