1. An elastic film, comprising:
a plurality of parallel elastic ribbons elongated in a longitudinal direction and spaced apart from each other in a transverse direction orthogonal to said longitudinal direction,
wherein said plurality of parallel elastic ribbons are coated on at least one surface by at least one skin layer continuous in said transverse direction which joins said plurality of parallel elastic ribbons to each other,
wherein said plurality of parallel elastic ribbons are coated on two opposite surfaces by first and second skin layers, and
wherein said first skin layer is continuous in said transverse direction and joins said plurality of parallel elastic ribbons to each other, and wherein the second skin layer is discontinuous in said transverse direction and coats surfaces of said plurality of parallel elastic ribbons opposite to said first skin layer.
