TL;DR
Housewrap seam tape is the manufacturer-matched pressure-sensitive tape that seals the overlaps, tears, and fastener-strip edges of a water-resistive barrier so wind-driven rain and air leakage cannot bypass the sheet at its joints. Wrap warranties and air-barrier performance both hinge on taping; an untaped barrier can lose much of its air-tightness value in blower-door terms.
What it means
Housewrap seam tape is the manufacturer-matched pressure-sensitive tape that seals the overlaps, tears, and fastener-strip edges of a water-resistive barrier so wind-driven rain and air leakage cannot bypass the sheet at its joints. Wrap warranties and air-barrier performance both hinge on taping; an untaped barrier can lose much of its air-tightness value in blower-door terms. Crews roll the tape onto dry, dust-free wrap, and generic packing or duct tapes fail quickly because their adhesives are not rated for the polyolefin surface or UV exposure.
