ETHYLENE-VINYLALCOHOL COPOLYMER ET3803
38 mol% Ethylene Content
General Description
Soarnol ET3803 is one of the standard grades of "Soarnol®", its ethylene content is 38 mol% with a low MFR(melt flow rate).
Soarnol ET3803 has both excellent barrier to gases as well as water resistance. This resin primarily used in coextruded film applications. Furthermore, it can also be used in coextruded sheet/thermoforming and shrink packaging.
