ABSTRACT:
A buryable warning tape comprises a length of woven polyolefin fabric. Visible indicia are printed on a first face of the fabric in ink which is essentially nondegradable during burial, typically an ink with a carbon-based pigment. A transparent polyolefin coating is bonded to and covers the first face. Preferably a second polyolefin coating is bonded to and covers the side of the fabric which is opposed to the first face. Such warning tape can have greatly increased tensile strength and tear strength over the warning tapes of the prior art, and the indicia have significantly improved durability.
