Weight control and “C” labelling with 1 g scale interval

With scale interval 1 g


The Challenge

A seafood processor required a packaging solution to ensure freshness, hygiene, and traceability for trays of marinated anchovies intended for retail distribution.

The system needed to:

  • Weigh each tray with 1 g accuracy.

  • Print and apply a long, information-dense label that would both seal the tray and display details such as logo, expiration date, and price.

  • Integrate smoothly with the existing production process while maintaining the highest hygiene standards.

  • Compressed air monitoring – A pressure switch detects and signals any drop in air pressure to safeguard consistent labeling operation.
  • Exit roller conveyor – Unloads compliant trays for accumulation on a platform, work surface, or directly into boxes.


The Solutions

To meet these requirements, a special weigh-price labelling system was provided.

Key features included:

  • Checkweigher with 1 g scale interval – Capable of weighing trays up to 1.5 kg, with rejection of non-compliant packs.

  • C-shaped labelling system – A long label is printed and applied so it wraps around both the top and bottom of the tray, securely sealing the package while providing extensive product information.

  • Brush-assisted adhesion – A fitted brush ensures the label adheres firmly to the tray surface for reliable sealing.

  • Guide railings – Adjustable lateral guides keep trays perfectly centered during weighing and labelling. Equipped with micrometer adjustment to hundredths of a millimeter, they allow quick adaptation for different tray sizes.

  • Compressed air monitoring – A pressure switch detects and signals any drop in air pressure to safeguard consistent labelling operation.

  • Exit roller conveyor – Unloads compliant trays for accumulation on a platform, work surface, or directly into boxes.


The Benefits

  • Compact footprint – In just over 1.5 meters, the system combines weighing, rejection, and labelling.

  • Legal-for-trade accuracy – MID-certified weighing ensures compliance for retail sales, with label weights carrying legal value.

  • Traceability and reporting – Integrated analytics software provides full batch traceability and production monitoring.

  • Efficient labelling – The “C” application method, combined with precision tray guidance, provides a secure seal and clear presentation of detailed product information.
