NNP heat shrink tunnel

• Shrink-wrapping individual food items or multi-packs for retail presentation.
• Sealing products to protect against moisture, dust, and tampering.
• Applying tamper-evident seals to jars and bottles.
• Creating collation packs for efficient handling and distribution.

Typical throughput

Throughput for this class of equipment typically ranges from 10 to 60 packs per minute, depending on product size and film type.

Power supply

Heat shrink tunnels commonly require a 3-phase electrical supply, typically 400V, 50Hz, with power consumption varying based on heater wattage.

Heating method

Units of this type commonly use electric heating elements to generate the required temperature for film shrinking.

Temperature range

Operating temperatures are typically adjustable, commonly ranging from 100°C to 250°C to suit various film types.

Belt material

For food processing applications, conveyor belts are typically made from stainless steel rollers or silicone-coated mesh for durability and hygiene.

Footprint

The overall footprint for a compact heat shrink tunnel is typically around 1.5m to 2.5m in length and 0.8m to 1.2m in width.

• What types of shrink film are compatible with this equipment?

  Heat shrink tunnels are typically compatible with various films, including PVC, POF (polyolefin), and PE (polyethylene), depending on the specific temperature control capabilities.
