Unimec - Semi Automatic Tray Sealer

• Sealing pre-filled trays of ready meals for retail or catering.
• Packaging fresh produce, such as fruit or vegetables, in modified atmosphere packaging (MAP).
• Sealing bakery products, including cakes and pastries, to extend shelf life.
• Packaging meat, poultry, and fish products in a hygienic and secure manner.
• Sealing individual portions of desserts or snacks for convenience.

Typical capacity

For this class of semi-automatic equipment, throughput typically ranges from 4 to 10 cycles per minute, depending on operator efficiency and tray size.

Power supply

Units of this type commonly require a standard single-phase 230V, 50Hz electrical supply, often with a pneumatic air supply for sealing mechanisms.

Construction material

As stated, this unit features all stainless steel construction, which is standard for food processing equipment to ensure hygiene and durability.

Tray compatibility

This unit is specified for GN1/1 trays, indicating compatibility with standard Gastronorm sizes. Many semi-automatic sealers can accommodate various tray dimensions with appropriate tooling changes.

Sealing method

Typically uses heat sealing to bond a film lid to the tray flange, often with options for vacuum or gas flushing (MAP) for extended shelf life.

Footprint

Semi-automatic tray sealers generally have a compact footprint, suitable for smaller production areas or as a secondary packaging station. Exact dimensions should be confirmed with the seller.

• What kind of film does this tray sealer use?

  Semi-automatic tray sealers typically use roll-fed lidding film, which is heat-sealable and compatible with the tray material. The specific film type will depend on the product and desired shelf life.

• Can this machine be used for Modified Atmosphere Packaging (MAP)?

• How easy is it to change tooling for different tray sizes?

• What maintenance is typically required for a machine like this?

• Is training required to operate a semi-automatic tray sealer?

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.
