A batch coding machine is a device used to mark or print information onto products in large batches. It can be used to print a wide range of information, including batch numbers, production dates, expiration dates, and product codes. The machine typically uses inkjet or thermal transfer technology to transfer the information onto the product through heat and pressure. It can be operated manually or automated and can be programmed to print different characters, fonts, and symbols. The machine is commonly used in the packaging, food and beverage, and pharmaceutical industries to ensure product traceability and compliance with regulations. It helps companies to accurately and efficiently label their products, reduce waste, and increase productivity.
