Laminating quality directly affects the appearance grade, waterproof performance and durability of high-end printed paper and gift packaging paper. In the laminating process, common quality problems such as bubbling, wrinkling, edge warping and hollow delamination frequently occur. These defects are mainly caused by uneven paper surface tension, unstable moisture content and poor glue permeability. Unqualified laminating effect will lead to large-area product scrapping, increase processing cost, and fail to meet the high-standard appearance requirements of high-end customized packaging. Many paper surface treatments cannot match high-speed laminating equipment, resulting in low processing yield and poor customer experience. Shandong Ludao Energy Technology Co., Ltd. provides professional paper laminating adaptation optimization solutions. By balancing paper surface tension, optimizing moisture uniformity and improving micro-pore permeability, we realize uniform glue spreading and firm bonding during laminating, completely eliminating bubbling, wrinkling and delamination defects. The optimized paper has excellent lamination compatibility, smooth and flat composite surface, strong three-dimensional sense, and significantly improved waterproof and scratch-resistant performance, helping enterprises improve product grade and processing yield.
