ML-2500 3D Sea Bag Intelligent Bag Making Machine

The Seaworthy Packing Bag Making Machine is designed for high-strength marine packaging applications. It supports all heat sealing materials, including pure PE, with a max film width of 2550mm and bag sizes up to 2400mm in both width and height. Operating at a steady speed of 3 pcs/min, this heavy duty bag machine is ideal for producing 3D sea bags used in bulk export, container lining, and moisture-resistant cargo protection.

Built on a 38-meter-long fuselage and weighing 22 tons, this machine ensures stable performance and precision sealing even for oversized bags. Whether for seaworthy liners, PE export bags, or heavy-duty 3D shipping bags, it delivers consistent quality and supports automated production needs for industries involved in ocean freight, bulk packaging, and international logistics.

Features

This machine is primarily used for producing three-dimensional shipping bags. Workers set process parameters such as bag size, quantity, and packaging process via a touchscreen, and the machine automatically produces bags according to the set parameters without manual intervention. The system features a precision bag sheet switching mechanism that quickly and accurately positions the bag sheets, ensuring consistent bag size accuracy and production speed. It is also equipped with a high-precision heat sealing device for rapid bag production. Additionally, it includes an automatic counting and statistics function, enabling proper documentation of the bag type and production time for each batch, facilitating production management.

1. Suitable for all heat-sealing materials, including single-material pure PE.

2. Bag type: three-dimensional bag with upper and lower valves.

3. Cross-generation automatic bag-making system integrating mechanical, electrical, and pneumatic components.

4. Controlled by Panasonic GM1 programmable controller.

5. Recipe management: Each product type generates its own dataset—sealing temperature, film tension, bag length, module positions, etc.—enabling accurate, repeatable production based on stored parameters.

6. Pulse heat sealing: No preheating required; 150°C for 0.85s heating and 60°C for 1s cooling—especially suitable for pure PE.

7. iPad split-screen control allows intuitive operation from any position on the machine.

8. One-touch format change: Instantly switch products without mechanical adjustments or debugging; supports up to 10,000 recipe sets.

9. Unwinding system: Servo-driven with ultrasonic sensing and automatic tension control for highly consistent multi-layer film tension.
