Ling Systems Stainless heat shrink tunnel

• Shrink-wrapping food products such as ready meals, bakery items, or bottled goods for tamper evidence and extended shelf life.
• Packaging non-food items like pharmaceuticals, cosmetics, or small electronic components in a protective film.
• Creating multi-packs of products for retail display or promotional bundling.
• Applying decorative or protective sleeves to containers for branding and product integrity.

Typical throughput

For this class of equipment, throughput can typically range from 10 to 60 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 power consumption varying based on tunnel size and heating elements.

Temperature range

Adjustable digital temperature controls on such tunnels typically allow for operating temperatures between 100°C and 220°C.

Footprint

A heat shrink tunnel with a 2500mm x 400mm belt commonly has an overall footprint of approximately 3000mm in length and 800-1000mm in width, including control panels.

Construction material

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

Belt type

Stainless mesh belts are commonly used for durability and even heat distribution, suitable for a wide range of product types.

• What types of film can this tunnel process?

  This type of heat shrink tunnel is typically compatible with various shrink films, including PVC, POF (polyolefin), and PE (polyethylene), depending on the specific film gauge and product requirements.

• Is this unit suitable for washdown environments?

• How is the temperature controlled?

• What maintenance is typically required for a shrink tunnel?

• Can the belt speed be adjusted?

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.
