Title (DE) SAUERSTOFFDICHTER KUNSTSTOFF UND DARAUS HERGESTELLTES VERPACKUNGSMATERIAL
(EN) OXYGEN-TIGHT PLASTIC AND PACKAGING MATERIAL PRODUCED THEREFROM
(FR) PLASTIQUE ÉTANCHE À L'OXYGÈNE ET MATÉRIAU D'EMBALLAGE FABRIQUÉ À PARTIR DE CELUI-CI
Abstract:
(DE) Die Erfindung betrifft einen Polymerblend, der 15 bis 70 Gew.-% Polyvinylalkohol (PVOH) und/oder eines PVOH-Copolymers sowie 30 bis 85 Gew.-% eines weiteren Polymers umfasst, ein Verfahren zur Herstellung eines Polymerblends, die Verwendung eines Polymerblends zur Herstellung eines Verpackungsmaterials sowie ein Verpackungsmaterial. Das aus dem Polymerblend gewonnene Verpackungsmaterial zeichnet sich insbesondere durch eine niedrige Gasdurchlässigkeit aus und lässt sich mittels kostengünstiger Verfahren herstellen.
(EN) The invention relates to a polymer blend comprising 15 to 70 wt.% of polyvinyl alcohol (PVOH) and/or of a PVOH copolymer as well as 30 to 85 wt.% of a further polymer, to a method for preparing a polymer blend, to the use of a polymer blend for producing a packaging material and to a packaging material. The packaging material obtained from the polymer blend is characterized in particular by a low gas permeability and can be produced by means of cost-effective methods.
(FR) L'invention concerne un mélange de polymères qui comprend 15 à 70 % en poids d'alcool polyvinylique (PVOH) et/ou d'un copolymère de PVOH ainsi que 30 à 85 % en poids d'un autre polymère, un procédé de production d'un mélange de polymères, l'utilisation d'un mélange de polymères pour la fabrication d'un matériau d'emballage ainsi qu'un matériau d'emballage. Le matériau d'emballage obtenu à partir du mélange de polymères est caractérisé en particulier par une faible perméabilité aux gaz et peut être fabriqué au moyen de procédés économiques.
