15 kW Non Woven Box Bag Making Machine

Non-woven bag making machines are predominantly fully automatic, high-speed industrial units that use ultrasonic sealing technology to produce various bag styles efficiently. They typically require a three-phase power supply for optimal operation. Key Technical Specifications Automation Grade: Primarily fully automatic, but semi-automatic and manual versions are available, usually for specific sealing tasks or small-scale operations. Production Capacity: Ranges from 20 to over 120 pieces per minute (PPM), depending on the bag type and machine model. High-speed models can reach up to 150 PPM. Bag Dimensions: Length: Commonly ranges from 200 mm to 600 mm (8 to 31 inches). Width: Typically from 100 mm to 800 mm (4 to 32 inches). Gusset (Bottom/Side fold): Up to 12 inches for box bags. Raw Material (Fabric): Uses non-woven fabric rolls with a basis weight/thickness of 15 GSM to 120 GSM (Grams per Square Meter). Power & Voltage: Most commercial machines require a three-phase power supply (380V or 440V) with a total power consumption of around 9 kW to 18 kW. Some models can run on single-phase 220V. Drive System: Operates via electric drive, often with servo or step motors for precision feeding, and an air supply (0.5-0.75 MPa) for pneumatic functions. Sealing Method: Uses advanced ultrasonic bonding technology for strong, heat-free sealing of all bag parts, including side seams, bottom, and handles. Control System: Integrated with a PLC (Programmable Logic Controller) and a human-machine touch screen interface for setting parameters, auto-counting, and error alarms. Machine Weight: Varies significantly with capacity, typically from 1,600 kg to over 4,000 kg. Common Bag Types ProducedThese machines can be configured to produce various bag styles by changing attachments or dies: D-cut (shopping bags) U-cut/W-cut (T-shirt style bags) Flat bags Box bags (3D/dimensional) Handle loop bags (requires an additional or integrated handle attachment unit)
