Coextruded articles comprising first and second layers each having first and second opposed major surfaces and between the first and second layers a series of first walls providing a series of microchannels, and methods for making the same. Embodiment of coextruded articles described herein are useful, for example, in cushioning applications where high levels of compression are desired. L'invention concerne des articles co-extrudés comprenant des première et seconde couches ayant chacune des première et seconde surfaces principales opposées et entre les première et seconde couches une série de premières parois formant une série de microcanaux, et leurs procédés de fabrication. Des modes de réalisation d'articles co-extrudés décrits dans l'invention sont utiles, par exemple, dans des applications d'amortissement où des niveaux élevés de compression sont souhaités.
