The RZJD-G450J flat bottom paper bag machine with window is designed for the production of larger-size food paper bags and can be used for bread, toast, bakery pastries, dried fruits, snacks, and other packaging applications. The machine continuously integrates hydraulic material loading, tension control, photoelectric positioning system, window processing, gluing, bag bottom folding, fixed-length cutting, and collection. This helps reduce material handling caused by separate window processing and bag-making operations, making it easier for packaging enterprises to organize orders for food paper bags with product visibility.
The machine adopts a servo motion control system, combined with SICK photoelectric tracking and a web guiding mechanism to coordinate paper feeding, window processing, and cutting positions. This helps reduce the impact of web deviation, misalignment of pre-printed graphics, and window position variations on finished products. The machine is compatible with commonly used materials such as kraft paper, greaseproof coated paper, and pre-printed paper, with processing conditions adjustable according to bag dimensions, window layout, and paper characteristics. The gluing system operates in coordination with the folding station, helping achieve more uniform bonding along the bag sides and bottom while balancing packaging appearance with practical packing requirements.
The touchscreen interface supports the storage of multiple sets of process parameters. When changing specifications, the corresponding settings can be recalled and fine-tuned according to trial-run results. The automatic lubrication system facilitates routine maintenance of transmission components, while alarm and shutdown functions for material shortage, paper jams, and operating deviations allow operators to troubleshoot abnormalities in a timely manner. The machine provides equipment support for continuous processing, order changeover management, and finished product consistency in the production of multi-specification flat bottom paper bags with windows.
