Proseal GTR

• Sealing pre-packaged meals and ready-to-eat products for retail.
• Packaging fresh produce, meats, and baked goods in a modified atmosphere.
• Ensuring hermetic seals for extended shelf life of various food items.
• Sealing medical devices and pharmaceutical products in a controlled environment.

Typical throughput

For this class of twin-head tray sealer, throughput can typically range from 30 to 60 packs per minute, depending on tray size and film type.

Power supply

Units of this type commonly require a single-phase 230V~ 50Hz supply, though some larger models may use three-phase.

Gas flushing capability

This feature allows for Modified Atmosphere Packaging (MAP), extending product shelf life by replacing air with a gas mixture.

Print registration

Essential for accurately aligning pre-printed film with the tray, ensuring consistent branding and presentation.

Tooling flexibility

Tray sealers commonly offer interchangeable tooling to accommodate various tray dimensions and materials.

Footprint

A twin-head unit typically requires a footprint of approximately 1.5m to 2.5m in length and 0.8m to 1.2m in width.

Materials compatibility

Units are typically designed to seal a range of tray materials, including foil, CPET, APET, and PP, with compatible lidding films.

• What is the primary benefit of a twin-head tray sealer?

  A twin-head configuration significantly increases production capacity compared to a single-head unit, as it can seal two trays simultaneously per cycle.

• How does gas flushing work and why is it important?

• What does 'print registration' mean for a tray sealer?

• Are spare parts readily available for Proseal GTR models?

• Can this machine handle different tray sizes?

• What kind of maintenance does a tray sealer typically require?

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.
