描述
EVAL F171B EVOH Resin is a high-performance ethylene vinyl alcohol copolymer produced by Kuraray. It is a standard EVOH grade widely used in multilayer barrier structures requiring excellent oxygen barrier performance and long-term packaging stability.
Kuraray EVAL resins are globally recognized for their outstanding gas barrier properties, which significantly reduce oxygen transmission and help extend shelf life of packaged products. EVOH materials are widely used in food packaging, medical packaging, and automotive fuel systems due to their excellent resistance to oxygen, aroma and hydrocarbon permeation.
EVAL F171B contains approximately 32 mol% ethylene, providing a balanced combination of barrier performance and processability. It is typically used in multilayer structures where EVOH is sandwiched between polyolefin layers such as PE or PP to protect it from moisture sensitivity and maintain long-term barrier performance.
According to technical datasheet data, F171B shows extremely low oxygen transmission rate (around 0.3 cm³·20µm/m²·day·atm at 65% RH), making it suitable for high-end barrier packaging applications.
Shenzhen Ruiqing International Trade Co., Ltd. supplies original Kuraray EVAL EVOH resins with stable supply, technical support and global delivery service.
