Description
1. Product Overview
EVOH Barrier Resin (Ethylene Vinyl Alcohol Copolymer) is a high-performance engineering thermoplastic renowned for its exceptional gas barrier properties, particularly against oxygen, carbon dioxide, and organic vapors. It is widely used in multilayer packaging structures across food, pharmaceutical, and industrial applications where product shelf life and integrity are critical. This material delivers a superior balance of transparency, flexibility, and barrier performance, making it a strategic choice for advanced packaging systems. In today’s sustainability-driven market, EVOH plays a key role in reducing food waste and extending product preservation without compromising recyclability in multilayer designs.
2. Key Specifications & Technical Characteristics

3. Core Industrial Applications
EVOH Barrier Resin is primarily used in multilayer film and packaging structures for industries requiring high oxygen barrier performance. Key applications include:
- Food packaging (fresh meat, dairy, processed foods, vacuum packaging)
- Pharmaceutical blister packs and sterile barrier systems
- Agricultural film systems for controlled atmosphere storage
- Industrial chemical packaging requiring odor and vapor containment
Compared to conventional polymers like polyethylene or polypropylene, EVOH provides orders-of-magnitude higher gas barrier efficiency, significantly extending product shelf life and reducing spoilage losses. Its compatibility with co-extrusion and multilayer lamination systems makes it highly versatile in modern packaging lines.
