SELECTIVELY PERMEABLE PROTECTIVE STRUCTURE AND ARTICLES THEREFROM

摘要

A selectively permeable protective structure and a method for limiting damage to the article due to corrosion or mold growth, comprising wrapping or covering the article in the selectively permeable protective structure. The selectively permeable structure comprises a membrane having a moisture vapor permeation value of at least 200 g-mil/m2/24h and barrier to liquid water, and optionally a supporting substrate. The membrane comprises an organic acid-modified ionomer, an ethylene/ (meth) acrylic/alkyl (meth) acrylate terpolymer and optionally an ethylene polymer.
