The present invention is related to a method for producing a multilayer structure comprising a thin polymeric layer (10) comprising the steps of : coextruding said thin layer on both sides of a support polymer layer (11) and forming a coextruded structure (7); laminating or extrusion coating at least one additional layer (16) on both sides of said coextruded structure; peeling-off said thin layers, along with the additional layers from said support layer (16) to build a multilayer polymer structure.
La présente invention porte sur un procédé pour produire une structure multicouche comprenant une couche polymère mince (10) comprenant les étapes consistant à : co-extruder ladite couche mince sur les deux côtés d'une couche polymère de support (11) et former une structure coextrudée (7) ; stratifier ou revêtir par extrusion au moins une couche supplémentaire (16) sur les deux côtés de ladite structure coextrudée ; éliminer par pelage lesdites couches minces, conjointement avec les couches supplémentaires à partir de ladite couche de support (16) pour construire une structure polymère multicouche.
