Abstract
The invention proposes a treatment method for the sterilization by irradiation of containers made of thermoplastic material. The method comprises at least an initial step of modification of the pitch consisting in selectively varying the initial pitch between two consecutive containers to increase the irradiation time of each container. The method also comprises an irradiation step consisting in irradiating each container from the outside with an electron beam emitted by at least one emitter of a sterilization device.
