- Typical throughput
- For this class of equipment, throughput can vary significantly based on product size and film type, but semi-automatic units commonly process dozens of packs per minute.
- Power supply
- Shrink wrappers and tunnels typically require a robust three-phase electrical supply, often 400V, 50Hz, with separate circuits for the wrapper and the higher-demand tunnel.
- Film compatibility
- Units of this type are generally compatible with various shrink films, including PVC, POF (polyolefin), and PE (polyethylene), depending on the application and desired finish.
- Product size range
- Shrink wrappers are designed to accommodate a range of product dimensions; buyers should verify the maximum and minimum product sizes suitable for their specific items.
- Footprint
- A combined shrink wrapper and tunnel system typically requires a significant operational footprint, often several metres in length, including space for loading and unloading.
- Maintenance requirements
- Regular maintenance for shrink wrappers includes cleaning sealing wires, checking conveyor belts, and inspecting heating elements for optimal performance.
