Soarus SoarnoL® ET3808 Ethylene Vinyl Alcohol Copolymer
Categories: Polymer; Thermoplastic; Ethylene Vinyl Alcohol (EVOH)

Material Notes: Ethylene content 38 mol%. Volatile matter 0.3%.

The gas barrier property of Soarnol is about forty times better than that of nylon, therefore, Soarnol allows design of lower cost packages by using a thin gas barrier layer without loss of shelf life.

Soarnol ET3808 with intermediate melt flow index is one of the standard grade of Soarnol, its ethylene content is 38 mol%. Since Soarnol ET3808 has both excellent gas barrier property and water resistance, this resin is suited for coextruded film, coextruded sheet and coextrusion coating. This resin can also be used in thermoforming and shrink packaging.
