Title (EN) A METHOD OF PRODUCING A PRINTING INK-DECORATED PACKAGING MATERIAL, IN PARTICULAR FOR ASEPTIC PACKAGES
(FR) PROCEDE DE PRODUCTION D'UN MATERIAU D'EMBALLAGE DECORE A L'ENCRE D'IMPRIMERIE ET DESTINE NOTAMMENT AUX EMBALLAGES ASEPTIQUES
Abstract:
(EN) The disclosure relates to a method of producing a printing ink-decorated packaging laminate for aseptic packages of the type which is produced in that a web of the packaging laminate is, for the purpose of sterilization, led through a bath of hydrogen peroxide prior to the reforming of the web into aseptic packages. The packaging laminate is produced in that a web of paper which has an outer coating of low density polyethylene (LDPE) is, for the purposes of promoting adhesion, subjected to a corona treatment modifying its polarity, whereafter the thus treated outer LDPE coating is provided with décor of water-based printing ink which is applied in the desired pattern on the outside of the coating. By subjecting the thus printing ink-decorated web to a surface energy-reducing after treatment, there will be obtained a packaging laminate which is susceptible to sterilization with considerably reduced consumption of hydrogen peroxide, at the same time as good adhesion between the water-based printing ink décor and the outer LDPE coating is ensured.
(FR) L'invention concerne un laminé d'emballage décoré à l'encre d'imprimerie, destiné à des emballages aseptiques et produit à partir d'une bande de papier continue. Avant d'être façonnée en emballages aseptiques, cette bande passe dans un bain d'eau oxygénée aux fins de stérilisation. Le procédé de production du laminé d'emballage consiste à soumettre une bande de papier continue, dotée d'un revêtement extérieur en polyéthylène de faible densité (LDPE), à un traitement par décharge corona changeant sa polarité afin de stimuler l'adhésion. La face extérieure du revêtement LDPE ainsi traité est ensuite pourvue d'un décor à l'encre d'imprimerie à base d'eau qui est appliqué selon le motif souhaité. En soumettant la bande continue décorée à l'encre d'imprimerie à une réduction d'énergie superficielle après traitement, on obtient un laminé d'emballage autorisant une stérilisation avec une consommation en eau oxygénée fortement réduite, ainsi qu'une bonne adhésion du décor à l'encre d'imprimerie à base d'eau sur le revêtement LDPE extérieur.
