- Typical throughput
- For this class of automatic L-sealer and shrink tunnel, throughput can typically range from 10 to 30 packs per minute, depending on product size and film type.
- Power supply
- Units of this type commonly require a 3-phase electrical supply, typically 400V, 50Hz, with varying amperage requirements based on tunnel heater power.
- Film compatibility
- This equipment is typically designed to work with various heat-shrinkable films, including PVC, POF (polyolefin), and sometimes PE, in roll form.
- Maximum product dimensions
- The sealing area and tunnel aperture will dictate the maximum product size; buyers should confirm specific dimensions with the seller.
- Footprint
- A combined L-sealer and shrink tunnel system typically requires a significant footprint, often several metres in length, plus space for loading and unloading.
- Control system
- Units commonly feature a PLC-based control system with a HMI for setting parameters such as sealing time, tunnel temperature, and conveyor speed.
