    Q
    What are the main functions and application areas of this block bottom valve bag machine?
    A
    It converts PP/PE tubular woven or laminated fabric into block bottom valve bags with integrated cutting, top folding, bottom folding, heat sealing, counting and stacking. Suitable for cement, chemicals, building materials, and food packaging (flour, rice) requiring high sealing performance, as an alternative to traditional sewn bottom bags.
    Q
    How is valve sealing and high-precision bottom forming ensured?
    A
    A pneumatic-hydraulic automatic edge correction system controls feeding, and hot air welding technology is used for bottom forming without glue, avoiding leakage and dimensional deviation. Bag width 350–600 mm, length 450–910 mm, bottom width 80–180 mm, maximum speed 120 bags/min, and coating adhesion ≥8N/3cm.
    Q
    What are the installed power and utility requirements for this machine?
    A
    Installed power is 105 kW. Cooling water requires a maximum of 18°C at 4 bar, and compressed air consumption is 500 m³/h at 6–7 bar.
    Q
    What coating weight and adhesion specifications apply to the outer sides?
    A
    Coating weight of outer sides is 18–30 g/m², with coating adhesion of minimum 8N/3cm.
    Q
    What is the overall dimension and weight of this conversion line?
    A
