Particularly at pharmaceutical labeling but also increasingly with cosmetics and foodstuffs, operators often need to integrate complex coding, serialization, monitoring and rejection systems into the labeling system. After all, particularly when it comes to vials containing vaccination serums, any mix-ups or cross-contamination can have fatal consequences and must be avoided at all costs. Reliable labeling and monitoring processes are therefore extremely important. Systems with a star wheel enable very precise product tracking since each product is handled individually.
