Testliner is used as a raw material in the production of corrugated cardboard

It is used for manufacturing internal and external layers of corrugated cardboard, between which there is a shock-absorbing fluted medium made of fluting.

Flat layers fix the position of the corrugation, keeping the form of corrugated cardboard and take up various external and internal loads.
Testliner provides strength and appearance of corrugated cardboard, its resistance to mechanical damage and moisture exposure
Testliner is produced from the waste raw material of the MS-5B grade following TU 5441-001-15064253-2016
