Application and development trend of color copperplate label paper

Here is a piece of news about the copperplate label paper:

According to the People's Forum network reported on May 29, 2024, Huaxin Color Printing, a subsidiary of state-owned enterprise Guanhao High-tech, has made important technological breakthroughs in the field of label printing, successfully developed a double copper paper coated label solution with excellent water resistance, and the project has been included in Huaxin Color Printing 2024 core research and development plan. Previously, the double copper paper coated label has the problem of insufficient water resistance after water-based coated treatment, especially when using some brands of water-based coated adhesive, such as Badfu, Hongfeng Hang, etc., although the paper film bonding effect is good at first sight, it is prone to the phenomenon of paper film delamination in the immersion environment, especially in tap water. The reason is mainly due to the high proportion of hydrophilic components in the coating material, which leads to limited water resistance, and the mismatch between the water-soaked expansion of the paper and the expansion of the coating, which reduces the bond strength and eventually leads to separation. In response to this pain point, Huaxin color printing team in-depth research on the water resistance mechanism of the laminating adhesive and its interaction with ink and paper base, after numerous experimental adjustments, the originality of the ultra-fine particle water resistant emulsion and high-strength alkaline resistant water-based resin combined to create a new generation of water-based laminating adhesive. After rigorous testing, the double copper paper coated label using the new glue, after soaking in water for up to 2 hours, the paper film bond is still stable, no signs of separation, fully demonstrating its durability. This technological innovation not only consolidated the high-end quality and market competitiveness of Huaxin color printing products, but also set a new technical benchmark for the entire label printing industry. Huaxin Color Printing will continue to deepen the research and development of printing technology, innovation-driven development, to provide more high-quality solutions for the market, and promote the green and sustainable development of the printing industry.
