The New Journey of Folder Gluers: From Digital Printing to Box Gluing

In recent years, digital printing has made significant breakthroughs in various printing segments, with packaging emerging as the largest opportunity market. Currently, corrugated paper printing may become the next important development area for digital printing in the packaging market. As the link between corrugated printing and folder gluing, folder gluers are undergoing profound transformation and innovation.

The rise of digital printing for corrugated paper is no coincidence. Against the backdrop of consumer upgrades, consumers’ demands for product packaging have expanded beyond basic protective functions to emphasize personalization, aesthetics, and the conveyance of brand essence. Digital printing technology perfectly meets these diverse needs, allowing for high customization of patterns and colors, creating unique appearances for each corrugated paper package. Whether it’s artistic illustration designs or accurately presented brand logos and product information, digital printing can flawlessly replicate these on corrugated boards, making packaging the best spokesperson for products on the shelf.

As the meticulously decorated corrugated boards are delivered to the folder gluer, the folder gluer itself is continuously evolving in this wave of transformation. It is no longer just a simple device for joining and gluing paperboards; it now possesses a higher level of intelligence and precision. The folder gluer can automatically adjust glue amounts, bonding pressure, and speed parameters according to the different sizes, shapes, and printing processes of the corrugated boards, ensuring that each box is securely formed and has a smooth, flawless appearance. For example, when dealing with printed boards that have special textures or localized gloss treatments, the folder gluer can intelligently recognize and optimize the bonding process to prevent glue penetration or uneven pressure from damaging the printed effect.

The automation level of folder gluers has significantly increased, achieving seamless integration and data exchange with upstream digital printing equipment and downstream packaging production lines. Through automated control systems, folder gluers can receive real-time order information and board specifications from the printing stage, automatically completing a series of processes including feeding, folding, gluing, bonding, and pressing, greatly reducing manual intervention and enhancing production efficiency and product consistency. Additionally, detection devices are integrated within the folder gluer, allowing for real-time quality monitoring of the glued boxes, such as checking adhesive strength, dimensional accuracy, and visual integrity. If defects are detected, the system can quickly sort out defective products, ensuring that the packaging products entering the market are of reliable quality.
