The method comprises the step of - introducing the material in a plastic recipient (20) having an inner layer and an outer layer. The inner layer has a melting point lower than the temperature reached during the heat treatment, whereas the outer layer has a melting point higher than the temperature reached during the heat treatment. - closing the plastic recipient in such a way that the inner layer is not appearing at the outer surface of the closed recipient. The invention further relates to a method of disinfecting or sterilising material.
