| 摘要 |
The invention concerns barrier films comprising: (i) a substrate comprising at least first and second coatings on the substrate;(ii) the first coating comprising an inorganic oxide, metal oxide or metallic coating; and (iii) the second coating capable of adhering to the substrates, wherein the second coating is polymeric; wherein the degradation of oxygen transmission rate is reduced when compared to a barrier film without the second coating when the barrier film is subjected to Gelbo-type flexing as described in ASTM F392. |
