hotfill bottle labeling system Automated Packaging Solutions for Labeling & Filling | Get Quote

Hot-fill bottle labeling systems are specifically engineered to handle containers that are filled with product at elevated temperatures (typically 80-95°C), such as juices, teas, or sauces. These machines account for the subsequent contraction of PET bottles as they cool, which can cause conventional labels to wrinkle or loosen if applied post-fill. In a typical hot-fill process, bottles are labeled immediately after capping while still hot and pliable, using heat-resistant adhesives or specially formulated glue systems that bond effectively during the cooling phase. The labeler must withstand high ambient heat and humidity near the filling station, often featuring stainless steel construction, heat shielding, and cooled components to protect sensitive parts. For example, a juice manufacturer would use this system to apply full-body shrink sleeves or paper labels that tighten smoothly as the bottle contracts, ensuring a wrinkle-free appearance. The system includes precision temperature monitoring to adjust label tension and application pressure dynamically. Additionally, these labelers are designed to handle potential bottle distortion during cooling without misapplication. For reliable labeling in hot-fill environments, we provide robust systems with validated performance.
