描述
EVAL G156B EVOH Resin is a high-performance ethylene vinyl alcohol copolymer produced by Kuraray. It is a high ethylene EVOH grade designed for applications requiring a balance of gas barrier performance, flexibility and excellent film forming behavior.
Kuraray is the global pioneer and leading producer of EVOH resin (EVAL™), first commercialized in 1972. EVAL materials are widely used in food packaging, medical packaging, automotive fuel systems and industrial barrier applications due to their outstanding oxygen barrier properties and ability to significantly reduce gas permeation.

According to technical datasheet information, EVAL G156B contains approximately 48 mol% ethylene content, making it one of the most flexible EVOH grades. It is especially suitable for stretch film and shrink film applications where flexibility and processability are more important than ultra-high barrier performance. (specialchem.com)
Typical oxygen transmission rate is around 3.7 cm³·20µm/m²·day·atm at 20°C / 65% RH, which provides sufficient barrier performance for many packaging applications while maintaining excellent flexibility. (specialchem.com)
In multilayer structures, EVAL G156B is usually used as a barrier layer sandwiched between polyolefin layers (PE or PP), which protects it from moisture sensitivity and ensures stable long-term performance.
Shenzhen Ruiqing International Trade Co., Ltd. supplies original Kuraray EVAL EVOH resins with stable supply, technical support and global delivery service.
