AI Overview
Ethylene vinyl alcohol (EVOH) is a high-performance, transparent thermoplastic copolymer known for its exceptional oxygen and gas barrier properties. It is widely used in food, pharmaceutical, and cosmetic packaging to extend shelf life by preventing spoilage, often co-extruded with materials like HDPE, PP, or PET to overcome its sensitivity to moisture.

What is the difference between EVA and EVOH?
Individually, the components exhibit markedly different tensile behavior in terms of yielding and ductility in the temperature range from 55°C to 95°C. The EVA blend deforms homogeneously whereas EVOH forms a neck at an extension rate of 10,000%/min.
