Absiegeln
Absiegeln is a German verb meaning to seal off or seal closed by applying a seal or closure. The term is formed from ab- (off, away) and Siegeln (to seal). The action is used to close an opening, container or space so that contents remain inside, leakage is prevented, and contamination or tampering is deterred. In packaging and food processing, absiegeln is common after filling to preserve freshness, prevent spills, and provide tamper evidence. Typical methods include heat sealing of plastic films to form a continuous seal, induction sealing of bottle closures with a foil liner, cold sealing using pressure-sensitive adhesives, and mechanical sealing with caps, lids, or clamps. The choice of method depends on product, material compatibility and required seal strength. In the pharmaceutical and beverage industries, absiegeln is often part of quality-control procedures and is accompanied by tamper-evident features such as inner foils or pull-off seals. In construction, mining or environmental work, absiegeln can refer to sealing off sections of a site or system to contain contamination, isolate areas, or stop the spread of pollutants.
