Abstract

The present invention relates to a multi layered lay-flat irrigation pipe, comprising an outer layer, and an intermediary layer, connected on its one side to said outer layer, and an inner layer, connected on its one side to the other side of said intermediary layer. The lay-flat irrigation pipe is characterized by its manufacturing by a continuous film blowing process, and said intermediary layer constitutes a reinforcing layer made of polyamide material.
