What are the multicoloured dots on yogurt containers for?

The multicoloured dots on yogurt containers are a part of the manufacturing process and serve several purposes:

Identification and Quality Control: The dots help in identifying different batches of yogurt during the production process. They are used for quality control purposes, allowing manufacturers to track and monitor the production dates, expiry dates, and any other relevant information related to specific batches. This enables efficient inventory management and helps ensure product quality.

Sorting and Packaging: The dots assist in automating the sorting and packaging process. Optical scanners read the dots to sort and group yogurt containers based on their batch information. This automation improves production efficiency and accuracy by reducing the risk of human errors.

Expiration Dates and Traceability: The dots can also encode expiration dates or other traceability information. This allows manufacturers to easily identify products that are approaching their expiry date and remove them from store shelves. It enhances food safety and helps in case of product recalls, as specific batches can be traced more efficiently.

Ingredient Information: Some manufacturers use dots to indicate specific ingredient information, such as whether the yogurt is made with whole milk, low-fat milk, or alternative milk options like soy or almond milk. This helps consumers quickly identify products that align with their dietary preferences.

By utilizing multicoloured dots on yogurt containers, manufacturers can optimize production processes, enhance quality control, provide important product information, and ensure efficient product management and traceability throughout the supply chain.
