Kraft Liners

Manufactured from softwood trees, Kraft paper consists of 70-80% “virgin” chemical pulp fiber, which results in a top paper grade that is very stiff and durable. Kraft paper is the most sustainable option out of all the types of paper. However, Kraft paper is also the most costly option.

· Brown Kraft may vary in natural brown color depending on the different fibers used, the pulping process, and the location of the paper mill

· White Top Kraft is very strong and affordable and offers excellent printing characteristics

· Mottled Kraft aka Oyster Kraft, similar to White Top Kraft with a mottled appearance

· Fully Bleached White is a Kraft liner with a natural look with an additional bleaching stage but this option is not as durable as the unbleached option

· Birch Faced Kraft similar materials as White Top Kraft, but the top ply is bleached

Test Liners

Test paper is a less costly option than Kraft. There is a higher percentage of recycled-fiber content, resulting in a less durable paper liner. The higher recycled fiber content also makes the paper more difficult to print. Which makes it very common to use Test paper as the inner linerboard of a corrugated box.

· Test 2 is partly recycled liner paper

· Test 3 is fully recycled liner

· White Top is a white-coated recycled liner

Flute Paper

· Semi Chem is virgin fibers using neutral sulfite semi-chemical process

· Waste Based Fluting is 100% recycled fibers

· Oyster is a mottled test liner
