The machine produces shopping-style kraft paper bags and can be adjusted to make a wide range of sizes. Supported ranges: cutting length 220–620 mm, finished bag length 210–610 mm, bag width 70–280 mm, gusset thickness 0–120 mm and standard flap 12–20 mm.
Maximum mechanical speed is 500 bags per minute (theoretical). Actual throughput depends on bag dimensions, paper quality, design (printed or laminated), and processing settings. At the maximum speed of 500 bags/min the theoretical output is 30,000 bags/hour; real-world rates are typically lower when using larger bags or additional processing.
The machine is designed for kraft and other paper types with a basis weight (thickness) between 30–80 gsm. It handles printed paper as well; for specialty laminates or much thicker paper, please consult the supplier for compatibility and testing.
Acceptable paper roll width is 220–700 mm, maximum roll diameter 1100 mm, and reel inner/core diameter 76 mm. Ensure your rolls match these dimensions for uninterrupted operation.
Machine dimensions (L×W×H) are 4670 × 1550 × 1500 mm. You should allocate additional working space around the machine for material handling, operator access and maintenance — typically at least 1–1.5 m clearance on accessible sides.
Core components include motor, pressure vessel, pump, PLC control system, gears, bearings, engine components and gearbox. The machine features an automated PLC-driven operation and precision mechanical subsystems for high-speed production.
The machine is designed with a user-friendly interface (PLC) and adjustable guides to simplify changeovers. Size adjustments are straightforward, but exact changeover time will depend on operator experience and the number of adjustments required. Training is recommended for efficient changeovers.
Routine maintenance includes regular cleaning of paper dust and debris, periodic lubrication of bearings and moving parts, inspection and replacement of cutting blades, checking belt tension and gearbox oil, and verifying pumps and electrical connections. Follow the supplier's maintenance schedule for intervals.
Common consumables and spare parts include cutting blades, glue or adhesive (if used), bearings, belts, fuses, electrical components, and wear parts for the feed and cutting systems. Keep critical spares on hand to minimize downtime; the supplier can advise a recommended spare-parts list.
Typical safety features include emergency stop buttons, mechanical guards and interlocks around moving parts, and safety signage. Operators should wear appropriate PPE such as safety glasses, hearing protection (if required), and avoid loose clothing. Follow the machine's safety manual and local regulations.
Electrical and utility requirements vary by configuration. Many industrial bag machines require a three-phase power supply and may need compressed air for pneumatic components. Exact voltage, current, and pneumatic specs should be confirmed with the supplier or on the machine nameplate prior to installation.
Yes — printed kraft paper is commonly used. Laminated or specialty coatings can be processed in many cases, but performance depends on coating thickness and adhesion properties. We recommend trial runs or consultation with the supplier for nonstandard stocks to ensure correct feed, cutting and sealing behavior.
Warranty terms, on-site training and after-sales support packages vary by manufacturer and vendor. Most suppliers offer a limited warranty, commissioning and operator training, as well as spare parts and technical support—confirm the specific terms with your seller before purchase.
Estimate production by measuring the actual running speed for your chosen bag size and multiplying by operation time. Example: actual speed (bags/min) × 60 = bags/hour. Note that larger bag lengths and additional processing steps will reduce bags/min compared with the 500 bags/min maximum.
Consider machine footprint and access for delivery (doors, forklifts), a level concrete floor able to support the machine, sufficient electrical power and utility hookups, lighting and ventilation, and a safe layout for material loading/unloading. Coordinate with the supplier for on-site installation and commissioning requirements.
