Abstract
Thin polymeric coating layers are often used to improve the barrier properties of packaging structures and container walls. We study how local flaws in the coating layers affect the overall permeation properties of such systems. We find that many small ‘‘holes’’ in a barrier layer are much more effective in compromising the system barrier properties than a few large ‘‘holes’’ with the same total area.This publication has 5 references indexed in Scilit:
