NN - John Quinn Shrink tunnel

• Used for packaging various products in a secure, tamper-evident, and aesthetically pleasing manner.
• Commonly employed in food processing for wrapping trays of produce, baked goods, or ready meals.
• Utilised in pharmaceutical and cosmetic industries for sealing individual products or multi-packs.
• Applicable in manufacturing for bundling components, protecting items from dust and moisture, or retail-ready packaging.
• Suitable for logistics and distribution centres requiring efficient product collation and protection.

Typical throughput

For this class of equipment, throughput can range from a few hundred to over a thousand packs per hour, depending on product size and film type.

Power supply

Shrink tunnels commonly operate on single-phase (230V) or three-phase (400V) power, with heating elements requiring significant amperage.

Temperature range

Adjustable temperature controls typically allow for operation between 100°C and 200°C, suitable for various shrink films.

Conveyor speed

Conveyor speeds are commonly adjustable, allowing optimisation for different product sizes and film characteristics.

Footprint

Units of this type typically have an overall length ranging from 1200mm to 2000mm, with varying widths and heights.

Tunnel aperture

Common tunnel apertures for compact units are around 300mm to 500mm wide and 150mm to 300mm high.

Construction material

Typically constructed from mild steel with powder coating, or stainless steel for food-grade applications.

• What type of shrink film can this equipment use?

  Shrink tunnels are generally compatible with various films such as PVC, POF (polyolefin), and PE (polyethylene), depending on the film gauge and required shrink temperature.

• Is installation complex for a shrink tunnel?

• What maintenance is typically required for a shrink tunnel?

• Can this unit handle different product sizes?

• What are the typical safety features on a shrink tunnel?

• How does a shrink tunnel integrate with other packaging machinery?

Ovens and sterilizing ovens hold strong reputations for reliability in laboratory and pharmaceutical settings. Buyers typically value robust construction and consistent temperature control. When purchasing used equipment, inspectors should verify heating element condition, temperature calibration accuracy, and chamber integrity. Common strengths include durability across extended operational lifespans and cost savings versus new models. Industry sentiment favours models from established manufacturers with documented maintenance histories. Thermal uniformity and energy efficiency remain key purchasing considerations.
