A SYSTEM AND PROCESS

摘要

A process for manufacturing paperboard liner (PBL) for plaster board, including the steps of receiving virgin Kraft fibre ( VKF); receiving recycled paper fibre (RCF); blending the VKF and the RCF to produce multiple fibre blend streams; forming said streams into paper plys; forming the plys into a multi ply paper sheet; chemically sizing the paper sheet to increase hydrophobicity; and drying the multi ply paper sheet over drying drums to produce the PBL, wherein the PBL is no more than 140 grams per square meter (gsm).
