Abstract
A tape seal for containers is provided. The tape seal comprises a strap mountable to locking bars of a shipping container, a tensioning device connected to the strap for applying tension to the straps after the straps are mounted to the locking bars, and an indicator affixed to the strap. The indicator has a first indicia coacting with the strap for indicating that the strap is at an initial tension and the container is secured. The indicator also has a second indicia also coacting with the strap for indicating that the strap is at a second tension less than the initial tension after the initial tension has been applied. The first indicia indicates that the strap is securely mounted to the locking bars and the second indicia indicates that the strap is not securely mounted to the locking bars thus indicating that there may have been tampering with the seal.
