Shrinkage deviation refers to the inconsistent shrinkage rate of paper in transverse and longitudinal directions, which is a key precision index restricting post-processing dimensional accuracy. During drying, temperature change and humidity fluctuation, paper fibers produce different degrees of shrinkage deformation due to directional arrangement difference. Excessive transverse and longitudinal shrinkage deviation leads to paper sheet distortion, size deviation, inaccurate die-cutting positioning and pattern deformation after printing. For customized size packaging paper, precision greeting card paper and multi-layer composite paper, shrinkage deviation will cause batch size mismatch and product scrapping. Most paper enterprises only control overall shrinkage rate but ignore directional shrinkage balance, and conventional drying process adjustment cannot eliminate inherent fiber directional structural differences, resulting in persistent shrinkage deviation defects. Shandong Ludao Energy Technology Co., Ltd. launches paper shrinkage balance optimization solutions. By adjusting fiber directional arrangement and balancing transverse and longitudinal fiber stress release, we unify the shrinkage rate of paper in all directions. The solution eliminates dimensional deviation and deformation caused by uneven shrinkage, improves post-processing positioning accuracy, and ensures batch dimensional standardization of customized precision paper products.
