| Machine Function | Automatic pickup, opening, filling, sealing, and discharge of pre-made bags | A bag magazine supplies empty bags to a gripper or vacuum pickup system. The bag is opened, positioned at the filling station, sealed after filling, and transferred to the outfeed conveyor. | Confirm whether the machine is designed for pre-made bags rather than forming bags from a roll of film. |
| Typical Output | 20–60 bags per minute | One complete operating cycle normally handles one bag, while faster configurations use multiple filling lanes or optimized indexing. | Actual output depends on product characteristics, bag size, filling method, sealing time, and the number of filling heads. |
| Bag Size Range | Approximately 80–450 mm wide and 120–700 mm long | Servo-driven positioning devices adjust the bag grippers and filling station to match the selected bag dimensions. | Provide the minimum and maximum bag width, length, gusset depth, and opening style before selecting a machine. |
| Compatible Bag Styles | Flat pouches, stand-up pouches, zipper bags, three-side-seal bags, four-side-seal bags, and gusseted bags | Different gripper jaws, vacuum cups, opening tools, and sealing assemblies are used according to the bag construction. | Bag samples should be tested because very flexible, dusty, or static-sensitive bags may require special handling components. |
| Common Bag Materials | PE, PP, PET laminates, aluminum-laminated films, paper laminates, and other heat-sealable structures | Heating bars or impulse sealing systems melt compatible thermoplastic sealing layers to create a closed package. | Sealing temperature, dwell time, pressure, and cooling requirements must match the actual packaging material. |
| Filling Technologies | Volumetric cup, auger, linear weigher, multihead weigher, liquid pump, and piston filler | The filling system measures the target product quantity and releases it into the opened bag before sealing. | Dry powder, granules, liquids, viscous products, and fragile products require different filling systems. |
| Typical Filling Range | Approximately 5 g to 5 kg, depending on the filler and bag format | The dosing device controls the product quantity through weighing, volume measurement, screw rotation, pumping, or piston movement. | Accuracy should be evaluated using the actual product, especially when the product has irregular particles, moisture, or poor flowability. |
| Dosing Accuracy | Commonly within ±0.5% to ±2% of target weight for suitable products and properly calibrated systems | Load cells, timed dosing, or volumetric controls regulate the amount released into each bag. | Accuracy is not a fixed machine value; it depends on product density, particle size, flow behavior, target weight, and operating speed. |
| Bag Pickup Method | Mechanical grippers, vacuum cups, or combined gripping and vacuum systems | Vacuum cups separate the front and back panels, while grippers hold the bag during transport, filling, and sealing. | Porous paper bags, dusty surfaces, and bags with strong static electricity may require modified vacuum or gripping arrangements. |
| Control System | PLC-based control with a touchscreen operator interface, servo drives, sensors, and recipe storage | Photoelectric sensors and position sensors verify bag presence, opening, filling position, and sealing conditions during each cycle. | Useful functions include automatic fault alarms, multilingual menus, password levels, data logging, and recipe management. |
| Compressed Air Requirement | Typically 0.6–0.8 MPa supply pressure; approximately 300–800 NL/min consumption | Pneumatic cylinders operate grippers, opening devices, clamps, and other actuators. | Air consumption varies with cycle rate, bag size, actuator count, and vacuum generation method. Clean, dry air is recommended. |
| Electrical Supply | Common configurations include 220–240 V or 380–415 V, 50/60 Hz, three-phase power | Electrical power runs the control system, motors, heaters, sensors, conveyors, and filling equipment. | Power requirements must be matched to the destination country, local electrical code, installed options, and total line equipment. |
| Installed Power | Approximately 4–15 kW for the main bagging machine, excluding some upstream and downstream equipment | Most installed power is used by sealing heaters, servo motors, conveyors, pumps, and the selected dosing system. | Actual operating consumption is usually lower than the rated installed power and depends on heater duty cycle and machine speed. |
| Sealing Temperature | Typically 120–220°C for many heat-sealable plastic laminates | Temperature-controlled sealing jaws apply heat and pressure for a defined time, followed by cooling or stabilization when required. | The correct temperature must be established through testing because each film structure has its own sealing window. |
| Changeover Time | Approximately 15–45 minutes for common size changes after tooling and recipe preparation | Operators adjust guides, grippers, filling height, sealing width, and software parameters for the new bag format. | Tool-free adjustment, digital position displays, and stored recipes can reduce changeover time and setup errors. |
| Machine Footprint | Approximately 2,000–4,500 mm long, 1,200–2,000 mm wide, and 1,800–2,400 mm high | The footprint includes the bag magazine, filling area, sealing station, control cabinet, and discharge conveyor. | Allow additional space for product feeding, finished-bag handling, maintenance access, electrical cabinets, and operator movement. |
| Product Contact Materials | Commonly stainless steel for product-contact parts; 304 stainless steel is widely used, with 316 stainless steel for more corrosive applications | Hoppers, chutes, filling tubes, and other contact parts are designed to minimize contamination and simplify cleaning. | Material selection should reflect product acidity, salt content, moisture, cleaning chemicals, and hygiene requirements. |
| Safety Features | Guard doors, emergency stops, interlock switches, overload protection, and fault alarms | The control system stops or inhibits hazardous motion when a guard is opened, an emergency stop is pressed, or a critical fault occurs. | Verify compliance with applicable local machinery safety rules and request a documented risk assessment for the complete production line. |
| Typical Applications | Pet food, snacks, grains, seeds, powders, detergents, chemicals, hardware, agricultural products, and household goods | The same basic bag-handling sequence is adapted with different dosing, sealing, cleaning, and dust-control equipment. | Food, pharmaceutical, chemical, and dusty products may require additional hygiene, containment, extraction, or washdown provisions. |
| Recommended Acceptance Tests | Capacity test, weight-accuracy test, seal-strength test, bag-drop test, leak test, and continuous-run test | The machine is evaluated with the buyer’s bags and product under agreed operating conditions before final approval. | Use the actual packaging materials and product whenever possible; define pass criteria for speed, accuracy, rejects, and seal integrity. |
| Maintenance Requirements | Daily cleaning and inspection; regular checks of vacuum cups, grippers, belts, sensors, heaters, lubrication points, and sealing jaws | Routine maintenance prevents bag misfeeds, unstable vacuum, poor sealing, product buildup, and unexpected downtime. | Keep common wear parts and sealing components available, and train operators to identify abnormal noise, temperature, and pressure. |
