Beschreibung
Zusammenfassung:	Subject-matter of the present invention is a method for removing at least one polymer component from plastic waste film material, wherein the plastic waste film material comprises at least a first polymer to be solved and a second polymer component, wherein the method comprises the steps of moving said plastic film material across at least one solvent bath which is filled with a solvent, wherein said solvent is a solvent for the first polymer component to be solved, and wherein at least the second polymer component is non-soluble in said solvent. La présente invention a pour objet un procédé d'élimination d'au moins un composant polymère d'un matériau en feuille à base de déchets plastiques, le matériau en feuille à base de déchets plastiques comprenant au moins un premier polymère à dissoudre et un second composant polymère, le procédé comprenant les étapes consistant à déplacer ledit matériau en feuille à base de déchets plastiques à travers au moins un bain de solvant qui est rempli d'un solvant, ledit solvant étant un solvant pour le premier composant polymère à dissoudre, et au moins le second composant polymère étant non soluble dans ledit solvant.
