The pandas will travel in two bespoke metal crates, with sliding padlock doors, pee trays and removable screens so keepers can check on them during the flight.
The boxes are 190cm long, 146cm high and 127cm wide – roughly 6ft by 5ft by 4ft.
The pandas will be accompanied on the 13-hour flight by a keeper from Edinburgh Zoo and an RZSS vet alongside a Chinese representative.
It is expected the animals will be quarantined for a brief period before being introduced to their new home in Sichuan province.
