FIBC manufacturing machinery systems

Polypropylene flat yarn extrusion lines

Continuous screw melt extruders engineered with multi-zone heating and precision chill rolls. Delivers tight denier stability across virgin and recycled resin blends under high-velocity take-up speeds.

Heavy-duty circular fabric looms

Cast-iron structural subframes dampen vibration across high-speed weaving of tubular bulk bag fabric. Electronic warp and weft tension control mechanisms minimize filament breakage during continuous multi-shift operation.

Automated cutting and slitting tables

Precision roll-to-sheet automated cutting units with integrated ultrasonic edge sealing and hole punching. Programmable servo-driven pull rollers deliver sub-millimeter tolerances on standard and baffle panel geometries.

Heavy sewing and loop attaching stations

Synchronized compound-feed lockstitch sewing heads configured for structural lifting loops and perimeter seams. High-clearance sewing arms easily accommodate dense multi-ply polypropylene fabric joins without stitch skips.

Four-stage manufacturing integration

Polymer extrusion

Circular weaving

Precision fabrication

Structural assembly

Raw polypropylene granules and stabilizing additives are melted, extruded into uniform tape film, water-quenched, and drawn into high-tensile flat yarns onto precision winders.

Yarn bobbins feed heavy circular looms to form seamless tubular fabric rolls or flat woven panels calibrated to exact breaking-load standards.

Automated roll-fed machinery executes continuous hot cutting, spout punching, and baffle slitting with sealed margins that eliminate loose threads.

Heavy-gauge industrial sewing heads attach corner lifting loops, top duffle spouts, and bottom discharge valves for final testing and pallet bundling.
