Ulma - Heating Shrink Tunnel

Applications & Use Cases

• Shrinking film around individual food products or multi-packs for tamper evidence and improved presentation.
• Securing products within their packaging for transport and retail display.
• Creating a tight, protective seal for various food items, extending shelf life and preventing contamination.
• Bundling multiple smaller items into a single, cohesive unit for easier handling and sale.

Typical Specifications

Typical throughput

For this class of equipment, throughput can typically range from 20 to 60 packs per minute, depending on product size and film type.

Power supply

Heating shrink tunnels commonly require a 3-phase electrical supply, typically 400V, with varying amperage requirements based on heating element power.

Tunnel aperture

The internal dimensions of the tunnel, such as the 65x100 (cm) indicated in the model number, define the maximum product size that can pass through.

Heating method

Units of this type commonly use hot air circulation, often with adjustable temperature controls for different film types.

Film compatibility

Typically compatible with various shrink films including PVC, POF (polyolefin), and PE (polyethylene), depending on the specific tunnel's design and temperature range.

Conveyor speed

Units commonly feature adjustable conveyor speeds to optimise shrink quality and match upstream/downstream equipment.
