| Shandong Ludao: Optimize Paper Embossing Adaptability |
Embossing adaptability determines finished yield and pattern delicacy of textured packaging paper and art decorative paper. In high-speed pattern embossing processing, many paper products have poor embossing fit, showing shallow pattern texture, pattern rebound, embossing cracking, surface coating peeling and uneven pattern depth. These defects come from unbalanced paper stiffness and toughness, insufficient surface ductility, unstable inter-fiber bonding force and uneven moisture content. Low embossing adaptability requires repeated secondary embossing, reduces processing efficiency, increases embossing die wear, and cannot present delicate three-dimensional texture. Most paper toughening schemes improve toughness but reduce surface hardness, leading to blurred embossed patterns, unable to meet high-definition embossing customization demands.Shandong Ludao Energy Technology Co., Ltd. optimizes paper embossing comprehensive performance. By adjusting fiber ductility structure, balancing surface hardness and internal flexibility, enhancing instantaneous pressure resistance, the paper fits high-speed precision embossing fully. It realizes clear three-dimensional patterns, no edge cracking, no pattern rebound, intact surface coating after embossing, reduces embossing defective rate, adapts customized art embossing processing, and improves added value of textured high-end paper. |
