Abstract:
Flexible tubing, particularly suitable for irrigation purposes, consists of a plurality of superposed, elongated, flexible strips, heat sealed along their longitudinal edges and is substantially flat when empty. At least one of said strips is thermoplastic and at least one has a permeable, fibrous structure and is preferably formed from a non-woven fabric such as spun-bonded polyethylene fiber.
