Abstract

L'invention se rapporte à des films polymères bi- ou multicouche comportant des parties ayant une forme régulée dans lesquelles au moins deux couches adjacentes ne sont pas scellées, lesdites parties étant visuellement distinctes du fond constitué par les autres parties du film où toutes les couches sont, de préférence, scellées les unes aux autres. L'invention se rapporte également au procédé de fabrication de tels films polymères.
