(PDF) Recent Updates on the Barrier Properties of Ethylene …
Although EVOH is intrinsically a better barrier, this can be explained by the fracture of the lamina structure of the EVOH. When EVOH/mPA blend was added to PP the barrier improved as the mPA content increased, reaching a minimum permeation, which was 113 times better than neat PP, at 83.3 wt% mPA in the EVOH/mPA blend.[118] 5.3.
