After freeze-drying process, un-cross-linked EVOH NFAs would be heated to form cross-linking network. The EVOH NFAs with different GA contents was shown in Fig. S4. With increasing GA contents, the volume of NFAs decreased. Moreover, exceeded GA would give rise to deformation of EVOH NFAs. This was because EVOH nanofibers are …Web

alcohols (EVOH) have lower transmission rates. Of these two, EVOH laminates are less expensive and can have oxygen transmission rates almost as low as the opaque aluminum-based films. Most barrier films include a polyethylene layer on the inner surface that enables them to be heat sealed at temperatures around 117 o C (350 o F). SealsWeb
