Pulping enzyme GR-M201 is a paper making bio enzyme preparation complexed by varieties of bio enzymes, it can change fiber nature under certain conditions. Add pulping enzyme GR-M201during pulping process, be flavor for peeling of S1 (secondary wall outer sphere), speed up destroy of cell wall and fiber devillicate brooming via mechanical force during defibrination process. The result is be more joint points between fibers, make fibers get absolute water absorption, to reduce energy cost, improve finished paper strength.
