MULTILAYERED FILM AND PRODUCTION THEREOF

摘要

PURPOSE:To obtain a multilayered film capable of being subjected to practical use while solving the generation of wrinkles and a problem inferior to interlaminar strength experienced at the time of the production of the multilayered film consisting of an EVOH layer and a TPU layer by an inflation co-extrusion method. CONSTITUTION:A TPU layer to which blocked isocyanate is added is laminated to at least the single surface of an EVOH layer. Or, when a multilayered film consisting of the EVOH layer and the TPU layer is produced by an inflation co-extrusion method, blocked isocyanate is added to TPU.
