Abstract

L'invention concerne un procédé de fabrication d'un emballage et de contrôle de la qualité. Ledit procédé comprend les étapes suivantes : A) la fabrication ou la préparation d'un matériau d'emballage (1) plat, au moins une substance luminescente (21, 22) étant introduite dans le matériau d'emballage (1) et la ou les substances luminescentes (21, 22) étant introduites, vues d'en haut, au moins dans les parties du matériau d'emballage (1) qui seront ensuite utilisées pour emballer un produit (3) ; B) l'emballage du produit (3) avec le matériau d'emballage (1) ; C) l'exposition du matériau d'emballage (1) à des électrons (e), un rayonnement gamma, un rayonnement X et/ou un rayonnement ultraviolet, de sorte que le matériau d'emballage (1) est stérilisé au moins en certains endroits ou qu'au moins une teneur en germes est réduite, l'allure spectrale et/ou temporelle de la luminescence de la ou des substances luminescentes (21, 22) étant modifiée au cours de l'exposition ; D) la lecture de la luminescence de la ou des substances luminescentes (21, 22) après l'étape C), servant à déterminer si l'étape C) a été effectuée correctement.
