The invention discloses a method for making high-strength fiber network sandwich paper bag paper by using non-plant fiber or chemical fiber, the process of which is as follows: cutting and opening the non-plant fiber or chemical fiber; Adding additives for refining; then high-frequency desorption, removing the agglomerates and residue from the centrifugal sieve, and concentrating, obtaining pulp, mixing with white water under the action of dispersant and softener, and mixing core slurry, The core of the paper bag paper is slanted online at the stacking machine; at the same time, the upper and lower layers of the paper are made by plant fiber pulp through the long line of the triple stack machine, combined with the core layer, and dried to obtain a high-strength fiber network sandwich. Paper bag paper. This technology can use secondary fiber as raw material to prepare core pulp, instead of natural plant pulp, reduce environmental pollution during production process, and greatly reduce manufacturing costs, solve the problem of low-cost high-strength network type paper bag paper manufacturing, is the update of plastic woven bags Replacement products have considerable market prospects.
