AI Overview
Automatic PP block bottom sack machines produce high-strength, stable, and stackable block-bottom valve bags (AD*STAR type) for industries like cement, fertilizers, and grains. These fully automated lines handle tubular, laminated PP woven fabric, forming the bottom, and applying hot-air sealing at speeds up to 120+ bags/min.
Key Features and Benefits
- High Efficiency & Automation: Automatic feeding, cutting, folding, and hot air welding of the bottom.
- Block Bottom Structure: Creates a brick-shaped bag that increases filling stability, improves stacking, and prevents sifting (leakage).
- Valve Technology: Designed specifically to create a valve opening for efficient, high-speed filling.
- Customization: Options include, for example, the PP Woven Flat Block Bottom Valve Bag Machine, which features customizable bag sizes and patch application for valve reinforcement.
Typical Production Process
- Unwinding/Feeding: Tubular PP woven fabric is unwound and fed.
- Gusseting: Side gussets are formed.
- Cutting & Folding: The tube is cut and the bottom is folded.
- Hot Air Sealing: The bottom is sealed using hot air welding technology for high strength.
- Finalizing: The bag is finished and ejected for packing, as described in the Paxon Packaging Automatic line video.
