Valmet has improved its solutions for linerboard applications through the Valmet Paper Lab, an automated paper testing laboratory.

With a new S-Test module, Valmet Paper Lab now offers a complete laboratory package for linerboard producers.

Compared to the standard manual laboratory procedure known as Concora Medium Test (CMT), the S-Test offers a new method for estimating the strength classification of containerboard medium fluting – there is no need to corrugate or tape the test pieces.


The S-Test has been standardized by German Institute for Standardization and confirmed by The Cepi Container Board, a European industry association of producers of corrugated case materials.

Among the other modules available at the Valmet Paper Lab are burst, tear, tensile strength, smoothness tests, caliper, basis weight, moisture, formation and more.
