METHOD FOR OBTAINING A HIGH-BARRIER MULTI-LAYER FILM, FILM, MATERIAL AND USE THEREOF IN PACKAGING, TISSUE ENGINEERING AND IN A BIO-POLYESTER

摘要

The invention relates to a method for obtaining a high-barrier multi-layer film that includes a) an inner layer that includes a polar substance and b) at least one coating that includes a substance that is hydrophobic and/or suitable as a barrier to water, characterized in that said method includes coating the inner layer a) with at least one coating b), using a spinning technique. The polar substance of the inner layer a) is preferably a substance suitable as a barrier to gases and/or vapors, and is sensitive to moisture. Likewise, the invention relates to the aforementioned multi-layer film, to a material including same and to various uses of the multi-layer film or the material.
