LF-DF Fully Automatic Folding Machine for Bottom Sealing Bag Making Machine

The LF-DF Fully Automatic Folding Machine is an inline downstream solution engineered specifically for high-capacity bottom-sealing bag production. It automates the precise double-layer folding of large, heavy-duty plastic bags directly after the cutting stage. By eliminating manual folding errors, ensuring smooth, non-deviating edges, and streamlining collection, it significantly enhances product aesthetics and cuts down labor overhead in industrial packaging lines.

Performance and Features

High-Precision Deviation Control: Advanced tracking sensors guarantee precise double-layer folding with straight, smooth creases, maintaining zero edge deviation even at maximum speeds.
Seamless Inline Integration: Perfectly synchronizes with your existing bottom-sealing bag making machines, adjusting its folding width automatically based on the master cutting machine's output.
Heavy-Duty Compatibility: Robustly handles thick materials including industrial HDPE, LDPE, and specialized heavy-gauge films used for medical waste bags and heavy-duty sacks.
Smooth & Wrinkle-Free Feed: Utilizes micro-tension pneumatic rollers to stabilize the film web during the folding stroke, preventing structural distortion or unsealed bottom stress.
Energy-Efficient Drive System: Powered by an optimized 3kW motor with a responsive servo control drive, striking the perfect balance between low power consumption and high processing speed.
Automated Batch Stacking: Smart batch counting system cleanly piles folded bags, minimizing manual intervention and prepping them directly for final downstream box packing or bundling.
