Abstract
A plastic drip irragation tape of unitary construction is disclosed that employs a water impervious polyethylene film folded lengthwise with the edges overlapped and joined together in a heat sealed seam to form a flat flexible conduit. A narrow preformed groove along one edge defines a small secondary conduit within the seam that resists deformation to maintain a consistent controlled drip rate along the tape. Breaks in the seam at regular intervals form inlets through which irrigation water flows from the main conduit into the secondary conduit and outlets through which the water is emitted from the secondary conduit to the soil.
