Ling Systems Stainless heat shrink tunnel

• Shrink wrapping food products such as ready meals, bakery items, or produce for extended shelf life and tamper evidence.
• Packaging pharmaceutical products, ensuring sterile and secure containment.
• Bundling multiple items together for retail display or logistical efficiency.
• Protecting products from dust, moisture, and damage during storage and transit.

Typical throughput

For this class of equipment, throughput commonly ranges from 10 to 40 packs per minute, depending on product size and film type.

Power supply

Units of this type typically require a 3-phase electrical supply, commonly 400V, 50Hz, with power consumption varying based on tunnel size and heating elements.

Temperature range

Operating temperatures are commonly adjustable, typically ranging from 100°C to 220°C, controlled digitally for precision.

Construction material

As indicated, stainless steel construction is standard for food processing applications, ensuring hygiene and corrosion resistance.

Belt type

Stainless steel mesh belts are commonly used, offering durability and suitability for high temperatures.

Footprint

While this unit specifies a 2500mm x 400mm belt, the overall machine footprint will be larger, typically requiring 3000mm to 4000mm in length and 800mm to 1200mm in width.

• What type of shrink film can this tunnel process?

  Heat shrink tunnels of this design are typically compatible with various shrink films, including PVC, POF (polyolefin), and PE (polyethylene), depending on the film gauge and required shrink characteristics.

• Is this unit suitable for washdown environments?

• How is the product conveyed through the tunnel?

• What maintenance is typically required for a shrink tunnel?

• Can this tunnel be integrated into an existing packaging line?

Used sealing machines are generally valued for their durability and long operational life. Buyers typically prioritize machines with clear maintenance histories and minimal wear on sealing components. Key considerations include film compatibility, seal quality consistency, and ease of adjustment. Reputable models tend to retain functionality well across multiple applications. Industry sentiment suggests these machines offer strong value when sourced from reliable vendors, though operators should verify calibration settings and test seal integrity before full production use.
