Import Doypack Filling And Sealing Machine — Buy in wholesale FOB from Supplier in China

The Unionpack International Co., Ltd. Doypack Filling And Sealing Machine is designed for automated packaging of solid, granular, powder, liquid, and thick liquid products in stand-up doypack bags. It operates with eight pairs of programmable bag clamps controlled by PLC, ensuring precise alignment and consistent sealing. The machine avoids filling or sealing if no bag is detected, eliminating waste and reducing material loss. Its filling range is 5 to 1500 grams, with a packing speed of 20 to 50 bags per minute, and it handles bag widths from 70 to 200 millimetres and lengths from 100 to 300 millimetres.

The machine uses grooved clamps instead of traditional end cams and springs, which improves durability and reduces mechanical failure. This design eliminates the need for spring return mechanisms, resulting in smoother, more stable operation over extended production cycles. The system includes a prevention feature that redirects improperly opened bags back to the feeding station, preventing empty or underfilled packages from proceeding. All components are built for industrial use with minimal maintenance requirements, and the machine runs on 3 kilowatts of power with a total weight of 1200 kilograms and dimensions of 1570 mm by 1440 mm by 1480 mm.

This equipment is commonly purchased by food processors, pharmaceutical manufacturers, and chemical distributors who require high-output, low-waste packaging for products such as coffee, spices, pet food, and liquid detergents. Buyers typically require the machine to integrate with existing production lines and meet hygiene standards for food-grade environments. Trade terms are FOB from Wenzhou port, with lead time and payment structure confirmed directly with the supplier.
