The present invention consists of a packing device for logistics of groups of wind turbine rotor blades, preferably of pairs of blades, including at least two structures (2), each one having a peripheral frame (4). For guaranteeing the proper conditions for the logistics, said blades are supported and fastened to the structures by flexible belts (7,8) stressed by ratchets, being said blade profile partially or entirely enveloped by said flexible belts. And alternatively, the device for logistics of groups of wind turbine rotor blades may include tip protection cover (13), blades fastening device (14), such as belts, ropes or chains, and protecting devices (12) on areas of contact between the blades to prevent the friction.
