描述
Chang Chun EVASIN EV3201 EVOH Resin is a high barrier ethylene vinyl alcohol copolymer developed by Chang Chun Petrochemical for multilayer packaging and automotive fuel system applications.
EVOH resin is known for its outstanding oxygen barrier capability, which can be thousands of times higher than conventional polyolefins such as LDPE. This property makes EV3201 particularly suitable for food packaging applications where aroma retention, shelf-life extension and product freshness are critical. It is commonly used as a barrier layer in multilayer films, bottles and thermoformed containers.
In addition to packaging applications, EVASIN EV3201 VT/FT is also widely used in automotive fuel system components. Its excellent resistance to hydrocarbons and fuel permeation makes it suitable for fuel tanks, fuel pipes and other barrier structures where emission control and safety performance are required.
The material also offers good transparency, mechanical strength and co-extrusion compatibility with polyolefins and other engineering resins. However, because EVOH is moisture-sensitive, it is typically used in multilayer structures where it is protected by outer polymer layers.

Processing Recommendations
EVASIN EV3201 EVOH Resin is typically processed via co-extrusion, film extrusion, blow molding and sheet extrusion. Because EVOH is sensitive to moisture, pre-drying before processing is recommended to ensure stable extrusion performance and optimal barrier properties.
In multilayer structures, EVOH is usually sandwiched between polyolefin layers (such as PE or PP) using tie-layer adhesives to ensure strong interlayer bonding. Proper layer design and processing conditions are essential to achieve maximum barrier performance.
