Damage sensor tape is a reactive tape Sam wraps around cargo he carries as a deliveryman. The tape contains a sensor in its threading which tells how much damage has been dealt to cargo by changing its color accordingly.
As seen in the nearby image, the benchmarker label on the tape reads: "The sensor is always active and will instantly develop color if damage is received. Match the tape's color with the reference chart to estimate damage. To extend the service life keep cold when not in use. Avoid prolonged exposure to heat and sunlight."
A replica roll of damage sensor tape is provided with the collector's edition of Death Stranding.
