Pull up seals are a type of security seal commonly used for tamper-evident purposes. These seals consist of a thin, flexible strip with a unique identification number or barcode. To secure an item, the strip is passed through a closure or fastening point and then pulled tight. Once tightened, the seal cannot be retracted or removed without leaving visible evidence of tampering, providing a visual indication of unauthorized access. Pull-up seals are frequently used in various industries, including transportation, logistics, and manufacturing, to ensure the integrity and security of goods during storage and transit.
