View ModelsVertical Form Fill Seal MachineRL-420 / 520 / 720 / 820
The RL-420 / RL-520 / RL-720 / RL-820 series forms bags from roll film, fills the product, heat seals each bag and discharges the finished package. A suitable feeding or dosing system can be selected for the product and fill weight.
RL-420 and RL-520 suit narrower bags and higher output, while RL-720 and RL-820 accommodate wider, longer packages. Together they cover bag widths from 80 to 400 mm, with double film pulling available for longer bags within each model’s limits.
Choose first by finished bag size and compatible film width, then by product flow, fill weight and required options. A larger model does not automatically mean higher output; actual speed depends on the bag, film and dosing process.
- Packaging Speed
- 5–80 bags/min (series range)
- Bag Width
- 80–400 mm (series range)
- Models
- RL-420 / RL-520 / RL-720 / RL-820
Packaging Material
- Heat-sealable laminated films: OPP/PE/PVC, OPP/CPP, KOP/CPP, ALU-FOIL.
- Single-layer PE film requires a dedicated PE film heat-sealing device.
