A sanitary device, e.g. a sanitary napkin is provided which has an absorbent matrix and a fluid impervious baffle. Part of the fluid impervious baffle is a heat fusible sheet which is adhered to the absorbent component by fusing. The absorbent component may have heat fusible material interspersed therein and may have a fluid pervious upper layer which is essentially coterminous with or wraps about the absorbent component or the absorbent component and baffle combination. When a fluid pervious wrap is used, it is preferred that the wrap be fusible and also be fused to the baffle. The fusing is preferably accomplished in random sites across the surface of the sanitary appliance, e.g. by embossing.
