What is the primary function of a heat tunnel?

A heat tunnel is designed to apply heat to shrink film, causing it to contract tightly around a product, creating a protective and aesthetically pleasing package.

What types of products are suitable for packaging with a heat tunnel?

Heat tunnels are commonly used for packaging a wide range of food products, including baked goods, ready meals, bottled drinks, and confectionery, as well as non-food items.

Is this unit suitable for continuous operation?

Heat tunnels of this calibre are typically built for continuous operation within industrial packaging lines, subject to proper maintenance and operational guidelines.

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 insulation for wear.

Can the temperature and conveyor speed be adjusted?

Yes, units of this type typically feature controls for adjusting both the tunnel temperature and the conveyor speed to achieve optimal shrink results for different films and products.
