Surface powder and fiber falling is one of the most common and troublesome quality issues in the paper industry, especially for recycled paper, low-grammage printing paper and coated paper. Loose surface fibers, unbonded fine fillers and residual powder particles will fall off during high-speed printing, automatic packaging and daily use. The falling powder will contaminate printing rollers, cause ink dot blockage and blurred printing patterns, and lead to a large number of defective printed products. In addition, powder falling will affect the surface cleanliness of finished paper, reduce product grade, and easily trigger customer returns and order complaints. Most traditional solutions simply increase adhesives, which easily causes hard paper texture, blocked air permeability and increased production costs. Shandong Ludao Energy Technology Co., Ltd. provides professional anti-powder-falling optimization solutions. By optimizing surface fiber bonding density and adopting high-efficiency surface strengthening agents, we lock loose fine fibers and fillers firmly on the paper surface, fundamentally solving powder falling and hair loss problems. The solution does not change the original hand feel, air permeability and printing adaptability of paper, effectively improves paper surface cleanliness and finish, reduces printing defective rate, and helps enterprises stabilize product quality and market reputation.
