Ultra Clean Filling is a high-hygiene standard filling technology applied in industries such as dairy and sensitive beverages, positioned between traditional clean filling and aseptic filling. The main goal of this technique is to achieve ESL (Extended Shelf Life), significantly extending the product’s shelf life under refrigerated conditions while maximally preserving its flavor and nutritional content. By operating within a positive-pressure clean environment utilizing HEPA filtration, combined with the strict sterilization of packaging containers (e.g., using H2O2) and equipment, Ultra Clean Filling effectively controls sources of microbial contamination, thus providing consumers with safer, higher-quality products with longer storage times.
