A batch coding machine, also known as a batch coder, is a piece of equipment used to print information onto products or packaging materials. It is commonly used in manufacturing and packaging industries to apply codes such as date, batch number, and product information. The machine uses different technologies, such as inkjet or thermal transfer printing, to mark the information on the material. Some batch coders are designed for continuous use, while others are more suited for intermittent or occasional use. The machine can help improve product traceability and quality control while ensuring compliance with industry regulations. It is available in various sizes and configurations to meet different production needs.
