Jumbo Bag Laminating Machine
LMJB Series
The LMJB series is a production line of plastic extrusion laminating machines. This machine is specifically designed for laminating PP circular woven jumbo bags. Its main design feature ensures that after laminating, the PP circular woven jumbo bags have a smooth surface without wrinkles, in addition to exceptional adhesive strength.
Purpose:
The LMJB series primarily functions to provide two types of laminating processes:
- Double-sided lamination of PP circular woven jumbo bags, which requires two coating processes to complete with one extruder. On the other hand, double-sided lamination can also be completed in one step with two extruders.
- Single-sided lamination of PP woven jumbo bags, which requires one coating process.
Features:
- A special screw design generates high-quality thin films with uniform discharge.
- PLC programming and HMI device, facilitating thickness setting, synchronized speed control, and parameter memory in operation.
- Automatic fabric detection and feeding function for the unwinding unit, and automatic fabric roll change function with speed setting for the winding unit.
- Automatic tension control system and specially designed guide wheels for maintaining the flatness of fabric rolls.
- Customized design options are available based on customer requirements.
