Promens Semi Auto Tray Sealer / Skin Packer

• Packaging ready meals, fresh meat, poultry, and fish in a modified atmosphere.
• Sealing trays for bakery products, salads, and prepared fruit.
• Creating skin packs for premium cuts of meat or delicate seafood.
• Packaging small batches of specialist food products for retail.

Typical capacity

For semi-automatic tray sealers of this class, throughput typically ranges from 4 to 8 cycles per minute, depending on tray size and operator efficiency.

Power supply

Units commonly operate on a standard industrial single-phase (230V, 50Hz) or three-phase (400V, 50Hz) electrical supply, often requiring a compressed air connection.

Tray materials

This type of machine typically handles a variety of tray materials including PP, PET, CPET, aluminium, and pulp, provided they are suitable for heat sealing.

Film types

Suitable for use with various lidding films, including barrier films for gas flush applications and specific films for skin packing.

Gas flush capability

Equipped for Modified Atmosphere Packaging (MAP) using inert gases to extend product shelf life, commonly requiring an external gas supply.

Skin pack facility

Allows for vacuum skin packaging, where film conforms tightly to the product and tray, enhancing presentation and shelf life.

Mould configuration

The 'twin impression mould' indicates the ability to seal two trays simultaneously per cycle, typically of the same size.

Footprint

Semi-automatic units are typically compact, designed for integration into smaller production areas or as part of a larger line.

• What is a semi-automatic tray sealer?

  A semi-automatic tray sealer requires manual loading and unloading of trays, but the sealing, gas flushing, and cutting processes are automated. This offers a balance between manual and fully automatic systems.

• What is gas flush and why is it important?

• What is skin pack facility?

• Can the mould be changed for different tray sizes?

• What kind of maintenance does this type of machine require?

• Is this unit suitable for high-volume production?

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.
