- 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.
