Drip tape is a type of thin walled dripperline used in drip irrigation. The first drip tape was known as "Dew Hose". Drip tape duct tape is made of polyethylene and is sold flat on reels. The wall thickness typically ranges from 4 to 25 mils (0.1–0.6 mm). Thicker walled tapes are commonly used for permanent subsurface drip irrigation and thinner walled tapes for temporary throw-away type systems in high value crops. Drip tape is a recyclable material and can be recycled into viable plastic resins for reuse in the plastics manufacturing industry.
