What is a heat tunnel used for?

A heat tunnel is used in conjunction with a shrink wrapper or L-sealer to apply heat to shrink film, causing it to contract tightly around a product or bundle. This creates a secure and protective package.

What kind of products can be processed?

Heat tunnels can process a wide range of products, including food items, pharmaceuticals, cosmetics, printed materials, electronics, and industrial components, provided they are suitable for shrink-wrapping.

Is this unit suitable for food contact applications?

While heat tunnels themselves do not directly contact the food, the film used and the overall packaging process must comply with food safety regulations. Buyers should verify the suitability of their specific film and process for food contact.

What maintenance is typically required for a heat tunnel?

Routine maintenance commonly includes cleaning the conveyor and heating elements, checking electrical connections, and inspecting the conveyor belt for wear and tear. Regular calibration of temperature controls may also be advised.

Can the conveyor speed be adjusted?

Yes, heat tunnels typically feature variable speed controls for the conveyor. This allows operators to optimise the dwell time in the tunnel for different film types and product sizes, ensuring optimal shrink results.

Typical context for this category of equipment. Always confirm specifics with the seller.

Shrink-wrapping individual products for retail display or protection.
Bundling multiple items together for transit or multi-packs.
Applying tamper-evident seals to product packaging.
Protecting products from dust, moisture, and damage during storage and shipping.

Typical throughput: Varies significantly by model, but for this class of equipment, typically ranges from 10 to 60 packs per minute, depending on product size and film type.
Power supply: Commonly found on units of this type are 3-phase electrical supplies, typically 400V, 50Hz, with power ratings often between 5kW and 15kW.
Tunnel dimensions (internal): Typically, the internal aperture width ranges from 300mm to 600mm, and height from 100mm to 400mm, with tunnel lengths often between 800mm and 1500mm.
Conveyor type: Units of this type commonly feature mesh belt or silicone-coated rod conveyors, with variable speed control.
Suitable film types: Typically compatible with various shrink films including PVC, POF (polyolefin), and PE (polyethylene), depending on the heating system and film gauge.
Temperature range: For this class of equipment, operating temperatures are commonly adjustable, typically ranging from 100°C to 220°C.

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.
