A layered tubing for conveying a non-toxic fluid comprises an inner layer having an inner surface adapted for exposure to the fluid, the inner layer consisting essentially of a polyester comprising units of the formula C.sub.10H.sub.8O.sub.4, and an outer layer comprising a thermoplastic polymer, the outer layer being bonded either directly or indirectly to the inner layer. Such a tubing is useful for conveying non-toxic fluids such as water, syrups and beverages. The polyester can also be used in the form of a film for packaging solids suitable for human consumption, such as food and medicaments.
