  Typical Pulp Properties...  
Aspen wood has a relatively low lignin content compared to other pulped hardwoods which makes the pulp easier to bleach. Bleached ECF pulps are available both at a standard brightness level(90%ISO) and sometimes higher brightness levels can be obtained(91-92%ISO). Like birch kraft, Aspen kraft pulps refine quickly producing a dense, smooth paper, but with less strength compared to birch pulp.


  Typical Uses...  

Aspen kraft pulp can be used in a variety of printing grades and is specifically useful where a higher brightness is required. Its high smoothness characteristics are particularly suited for coated papers to be gravure printed.
