Abstract: A system is provided for the protection of luggage, based on the application by thermic effects of a polyethylene retractile material around the luggage in order to obtain an external protection against damage produced by possible improper handling. It includes an oven having top, lateral and bottom walls and inside the oven a set of electric resistances, a fan, a thermostat and on the front side a curtain made of an insulating material covering the entrance to oven. The system presents a horizontal conveyor to introduce the luggage into the oven or taking it out. The conveyor is provided with a proximity detector and the system has an electric board to command and control all automatic functions of the system. The ceiling, bottom and lateral walls of the oven are built by means of a structure with a double layer of metal plates and between them an insulating material is placed, the thickness of this being bigger in the ceiling than in the lateral walls and in the lateral walls bigger than in the bottom wall.
