Cutting quality directly affects the finished product yield and appearance grade of paper products. In the post-processing stage, problems such as burrs, rough cut edges, edge fluffing and irregular incision often occur during paper slitting and cutting. These cutting defects are mainly caused by unstable paper toughness, uneven fiber distribution and inappropriate surface friction coefficient. Rough edges will cause paper layer separation and powder falling in subsequent processing, and burr defects will directly lead to product unqualified and customer rejection. Many enterprises only rely on upgrading cutting equipment, but cannot fundamentally solve the problem from paper performance. Shandong Ludao Energy Technology Co., Ltd. provides professional paper cutting performance optimization solutions. By balancing paper fiber toughness and surface compactness, optimizing internal structural uniformity, we effectively eliminate edge fluffing and burr problems during cutting, make the incision smooth and neat, and improve cutting precision and finished product flatness. It greatly reduces post-processing defective rate, improves product appearance quality, and adapts to high-precision automatic cutting production.
