| 摘要 |
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. |
