Comunetti

• Sealing pre-formed bags in coffee roasting and packaging operations.
• Packaging of dry goods such as grains, pulses, and snacks.
• Used in food processing for sealing various product types into bags.
• Suitable for packaging non-food items like pet food, chemicals, and aggregates.
• Often found in small to medium-scale production lines requiring reliable bag closure.

Typical capacity range

For this class of equipment, units commonly handle bag weights from 250g up to 3000g or more, depending on bag type and product density.

Sealing mechanism

Comunetti bag sealers typically utilise heat sealing technology, often with a continuous band sealer design.

Bag material compatibility

Units of this type are generally compatible with various heat-sealable film materials, including laminates and co-extrusions.

Conveyor type

An electrically controlled height-adjustable conveyor is a common feature, allowing integration with different upstream and downstream equipment.

Power supply

Typically requires a standard industrial electrical supply, commonly 230V, single-phase, or 400V, three-phase, depending on the model and motor power.

Throughput

Throughput for continuous band sealers can vary significantly but is typically in the range of 5-20 metres per minute, depending on bag size and operator efficiency.

Footprint

For this type of bag sealer with an integrated conveyor, a typical footprint might be around 1.5 to 2.5 metres in length and 0.8 to 1.2 metres in width.

• What types of bags can this machine seal?

  This type of machine is designed to seal pre-formed, heat-sealable bags, commonly made from various plastic films or laminated materials. It's suitable for stand-up pouches, gusseted bags, and pillow bags.

• Is this machine suitable for vacuum sealing?

• What maintenance is typically required for a bag sealer?

• Can this machine be integrated into an existing production line?

• What safety features are commonly found on these units?

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.
