Abstract

A longitudinal seal having a cross section comprising a wall around an inner section; wherein the wall is formed of a material which is configured such that a physical characteristic of the material varies by at least 10% along at least one of a length and the cross section of the seal, the variation in the physical characteristic causing a variation in at least one of a deformability and a resilience of a corresponding portion of the seal.
