Abstract

A perforated covering structure is described for hygienic-sanitary products, such as sanitary towels for women, comprising an upper layer constituted by a non-woven textile of fibers of hydrophobic material, an intermediate layer or core constituted by a film of hydrophobic material, and a lower layer also constituted by a non-woven textile of fibers of hydrophobic material. The covering structure is applied in direct contact with that face of the absorbent core of the product which is intended to face the body of the user in use.
