描述
EVASIN EV3851 V/F EVOH Resin is a high-performance ethylene vinyl alcohol copolymer (EVOH) resin produced by Chang Chun Petrochemical. It is designed for multilayer barrier applications requiring excellent oxygen barrier performance, good processability and stable thermal behavior during co-extrusion processing.
EVASIN EVOH resins are widely used in packaging and industrial barrier systems due to their outstanding ability to block oxygen and gases. EV3851 V/F provides a balanced ethylene content that delivers both strong barrier performance and reliable processing stability in film, sheet and bottle structures.
In multilayer packaging systems, EVASIN EV3851 is typically used as a barrier layer sandwiched between polyolefin materials such as PE or PP. This structure significantly improves shelf life of packaged food products by reducing oxygen and aroma transmission.
In addition to food packaging, EVASIN EV3851 V/F EVOH Resin is also used in automotive fuel system applications such as fuel tanks and fuel lines, where it helps reduce fuel permeation and improve environmental safety performance.
Because EVOH materials are moisture-sensitive, they are generally used in multilayer structures with protective outer layers. When properly designed, EVASIN EV3851 provides excellent long-term barrier performance and durability.
Shenzhen Ruiqing International Trade Co., Ltd. supplies original Chang Chun EVASIN EVOH resins with stable sourcing, technical support and global delivery.

Processing Recommendations
EVASIN EV3851 V/F EVOH Resin is typically processed via multilayer co-extrusion, blown film extrusion, sheet extrusion and bottle forming.
Because EVOH is hygroscopic, drying before processing is recommended to ensure stable extrusion performance and optimal barrier properties.
In multilayer structures, EVOH is commonly used between PE or PP layers with tie-layer adhesives to ensure strong bonding and structural integrity.
