Premium Test Liners

Linerboard made of virgin pulp is called kraftliner, however recycled linerboard is known as testliner. Testliner is used for the outer and intermediate plies of corrugated board. Its printability is very good. Testliner is produced from 100% recyclable and made from renewable resources, with coloring agents providing a stable optical colour. It is available in different colour shades like golden yellow, natural shade and brownes shade. BF range of test liner from 22 to 35. GSM ranges from 140 to 300.
