A flexible hose for transporting food liquids, particularly for irrigation
or the like, comprising at least one outer protective layer (2) of a
first flexible polymer material and at least one inner layer (3) in
direct contact with the fluid to be transported, made of a second
flexible polyvinyl chloride (PVC)-containing polymer material. The second
polymer material includes a plasticizer agent having as low a migration
level as to maintain the flexibility of said second polymer material
substantially unaltered with time. The plasticizer agent is selected from
the group comprising non-phthalate additives, so that it can be non-toxic
and non-polluting for the food products to be transported.
