Title (EN) APPARATUS AND METHOD FOR MANUFACTURING A PACKAGING MATERIAL
(FR) APPAREIL ET PROCEDE DE FABRICATION D'UNE MATIERE D'EMBALLAGE
Abstract:
(EN) An apparatus (20) and process are disclosed for forming a barrier layer, such as an SiOx barrier layer, onto a moving web of substrate material (35) in a continuous process at atmospheric pressure using a precursor coating on the web and an oxidizer (65) that are irradiated by an ultra-violet energy source (100).
(FR) L'invention porte sur un appareil (20) et le procédé associé servant à former une couche isolante, par exemple de SiOx sur une bande d'une matière de substrat (35) selon un processus continu sous une pression atmosphérique, à l'aide d'un revêtement précurseur placé sur la bande et d'un oxydant (65) irradié par une source d'UV (100).
