As a professional manufacturer specializing in the research and manufacturing of paper bag machinery, we introduce the RZFD-330W square bottom paper bag machine (window). Built around the core design concept of “window customization and precise integration,” this model is specifically developed for packaging applications that require intuitive product visibility, providing a professional square bottom paper bag production solution that combines visual presentation with practical functionality.
The machine covers the full production process, including roll paper unwinding, window die-cutting, precise creasing, bag body forming, square bottom gluing, and finished bag cutting. Relying on a digital control system, window processing and bag-making operations are completed synchronously, eliminating the need for secondary manual processing and significantly improving production efficiency compared with traditional segmented equipment. In terms of performance, the machine is equipped with a high-precision die-cutting unit and a photoelectric positioning system, enabling window size deviation to be controlled within a very small range while maintaining smooth and clean cut edges without burrs. Overall bag size accuracy remains stable and reliable. Combined with an intelligent constant-temperature gluing system, the machine can adapt to commonly used base materials such as kraft paper and white cardboard across different grammage ranges, ensuring firm and neat bonding without glue overflow. The finished paper bags exhibit excellent stiffness and sealing performance, fully meeting packaging requirements for various light- to medium-load products.
The machine adopts a modular design architecture to meet production requirements for square bottom paper bags in multiple specifications. With one-button switching of relevant production parameters, it can quickly adapt to different order processing needs, maintain stable daily output over long-term operation, and effectively reduce material waste. The window film can be matched with food-grade transparent materials to meet hygiene and safety requirements for direct food contact. Combined with a low-energy motor design, the machine aligns well with current green and low-carbon production trends.
Whether for bakery food enterprises that need to visually display product appearance, or for daily chemical brands that emphasize packaging aesthetics and brand texture, the RZFD-330W square bottom paper bag machine (window) delivers reliable window-processing technology and efficient continuous production capability. It helps enterprises enhance the added value of packaging products while optimizing order delivery efficiency.
