<p><P>PROBLEM TO BE SOLVED: To provide rolled newsprint paper having high surface peeling strength (pitch breakage) capable of reducing the generation of surface peeling due to an adhesive material in a print process in a rotary press with a steel belt in spite of its main raw material of a recycled pulp. <P>SOLUTION: The rolled newsprint paper mainly made from a recycled pulp has a peeling index of no greater than 290,000 mm<SP POS="POST">2</SP>/m<SP POS="POST">2</SP>calculated with an adhesion area of an adhesive material to an adhesive tape. The rolled newsprint paper contains at least cationic colloidal silica and white carbon as a filler and has an ash content rate of 5 to 10 wt%. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
