描述
EVAL H171B EVOH Resin is a high-performance ethylene vinyl alcohol copolymer produced by Kuraray. It is a standard high-ethylene EVOH grade designed for multilayer structures requiring a balance of oxygen barrier performance and processing stability.
Kuraray is the inventor and leading global producer of EVOH resin (EVAL™), widely used in food packaging, medical packaging, automotive fuel systems and industrial barrier applications due to its outstanding gas barrier properties. EVOH materials significantly reduce oxygen and aroma transmission, helping extend product shelf life and preserve quality.
EVAL H171B contains approximately 38 mol% ethylene content, which provides better processability and longer extrusion stability compared with lower ethylene grades, while still maintaining strong oxygen barrier performance.
Typical oxygen transmission rate is around 0.7 cm³·20µm/m²·day·atm at 65% RH, making it suitable for standard high-barrier packaging structures.
In multilayer applications, EVAL H171B is typically used as a barrier layer sandwiched between polyolefin layers (PE or PP) to protect it from moisture and maintain long-term barrier performance.
Shenzhen Ruiqing International Trade Co., Ltd. supplies original Kuraray EVAL EVOH resins with stable supply, technical support and global delivery service.
