Pulp blends for linerboards |
摘要 |
A process for preparing linerboards from blends of Kraft chemical pulp with a Kraft high yield pulp comprises forming the pulp blend into sheets, pressing the sheets to a specific solids content and subsequently pressing at a press impulse of at least 7.5 psig-second. The linerboards have the same crush strength as those prepared from Kraft chemical pulps.
