The production technology, equipment selection, quality performance and the application of light weight printing paper are probed in the paper. In order to ensure the bulkness of the sheet, high-yield chemimechanical pulp is applied as main material, and higher beating degree is required with neutral sizing, dual retention system of cationic starch and polyacrylamide, less filler added, and the press part and calender are operated with low linear pressure and soft roll calendering is preferred. The configuration of 3520/800 multi-cylinder Fourdrinier paper machine for the light weight printing paper is also introduced.
