- Typical throughput
- For this class of equipment, throughput commonly ranges from 5 to 30 packs per minute, depending on product size and film type.
- Power supply
- Shrink tunnels typically require a 3-phase electrical supply, commonly 400V, 50Hz, with power consumption varying based on tunnel size and heating elements.
- Tunnel dimensions
- The internal tunnel dimensions for units of this type commonly accommodate products up to 400-600mm in width and 200-400mm in height.
- Film compatibility
- Units are typically compatible with various shrink films, including PVC, POF, and PE, with film thickness commonly ranging from 12 to 80 microns.
- Heating method
- Most shrink tunnels utilise electric heating elements, often with adjustable air velocity and temperature controls.
- Construction material
- While many are painted steel, units designed for specific environments, such as the food industry, are commonly constructed from stainless steel.
