ETHYLENE-VINYLALCOHOL COPOLYMER E3808
38 mol% Ethylene Content
General Description
Soarnol E3808 is one of the standard grades of "Soarnol®", its ethylene content is 38 mol% with an intermediate MFR(melt flow rate).
Soarnol E3808 has both excellent barrier to gases as well as water resistance. This resin primarily used in coextruded film and coextrusion coating applications. Furthermore, it can also be used in thermoforming and shrink packaging.
