What is Batch Coding?

What is a Batch Number?

In industrial terms, the batch number (or batch code) is the designation, in numbers and/or letters, used to identify and trace a set of identical products that share certain characteristics of production (production time, production date, identification code, etc.).

Generating and applying these batch codes is the core of the batch coding process, it ensures product traceability and that data on the history and background of the product are retained through the supply chain. This coding process is commonly used in the pharmaceutical, cosmetics, food, beverage, and consumer packaged goods industries – where traceability is crucial both to protect consumers and to comply with legal regulations.

What is a Batch Coding Machine?

Batch codes are typically applied directly to products and primary packaging by an automatic batch coding machine, which is integrated into the production line. Often these applications can involve high speed coders on multiple lines operating on a 3 shift or continuous production pattern.

Batch number printers or batch coders are terms commonly used by operators and maintenance managers for these coding machines. Batch information may also be printed onto the secondary packaging – such as cartons, cases and cardboard boxes.

Several different types of marking equipment can be used for industrial batch coding, including:

Depending on the support surface on which the batch code is printed (e.g. plastic bags, cardboard boxes, cables, heat shrinkable sleeves, raffia sacks, sacks, kraft paper bags, PET bottles, metal or any other material), Videojet offers different options for batch coding your product.
