Method for preparing a selectively permeable protective structure |
摘要 |
A method for preparing a multilayer package comprising a substrate and a composition having a moisture vapor permeation value of at least 200 g-mil/m2/24h and barrier to liquid water. The method comprises melt blending an organic acid-modified ionomer with an ethylene-containing copolymer and a copolymer comprising a dicarboxylic acid derivative as a comonomer to provide a composition and applying the composition to the substrate in a molten condition and allowing the composition to cool and solidify. |
