Abstract
The present invention discloses a light-weight coated printed paper and its making method. It includes the following steps: using bleached sulfate needle wood (pulp (BKP). Italia poplar alkaline hydrogen peroxide hot-ground mechanical wood pulp (APMP), bleached sulfate reed pulp (BKP) or commercial bleached hard wood pulp; respectively beating, proportioning and making them into mixed pulp; adding auxiliary material to obtain material for making paper and making paper. Said invention adopts the advanced making process of AKD neutral sizing, internal coating and calendering by using soft roll, so that said printing paper has good surface strength, bulkness and air permeability, and is suitable for implementing various colour printing.
Description
Technical field
The present invention relates to a kind of light weight coated printing paper and manufacturing technique thereof.
