Complete Guide on EVOH (Ethylene Vinyl Alcohol): Barrier Resin, Applications, Grades & Market Insight


1. What is EVOH? | Full Form and Definition

EVOH stands for Ethylene Vinyl Alcohol Copolymer, a high-barrier thermoplastic resin derived from ethylene and vinyl alcohol monomers. Known for its exceptional gas barrier properties, EVOH is widely used in food packaging, medical containers, and industrial films.


2. Key Features of EVOH

  • Outstanding oxygen and gas barrier

  • Excellent clarity and gloss

  • High mechanical strength

  • Resistant to organic solvents and oils

  • Compatible with multilayer structures (PE, PP, PA, PET)

  • Non-toxic and food-safe


3. Grades and Types of EVOH

Grade Applications
High Ethylene Content Better flexibility and processability
Low Ethylene Content Superior barrier but stiffer
Injection Grade Bottles, caps, closures
Extrusion Grade Films, sheets, multilayer packaging
Blow Molding Grade Containers for food, pharma, and agrochem

4. Applications of EVOH

  • Food Packaging

    • Vacuum pouches, meat trays, cheese films

    • Retort packaging and multilayer bottles

  • Medical and Pharmaceutical

    • Sterile containers, IV bags, blister packs

  • Cosmetic and Personal Care

    • Tubes and barrier bottles for creams, lotions

  • Agricultural Use

    • Pesticide and fertilizer containers

  • Automotive and Industrial

    • Fuel system components, brake fluid bottles


5. Benefits of Using EVOH in Packaging

  • Increases shelf life by preventing oxygen ingress

  • Reduces food waste

  • Lightweight alternative to glass and metal

  • Recyclable in multilayer form (with PE or PP)

  • Retains aroma, flavor, and freshness of contents


6. Properties of EVOH

Property Typical Range
Oxygen Transmission Rate Extremely Low (< 1 cc/m²/day)
Melting Point 160°C – 190°C
Density ~1.12 – 1.20 g/cm³
Transparency High clarity and gloss
Moisture Sensitivity Moderate (needs protection in humid use)
Compatibility PE, PP, PA, PET, adhesives (tie layers)

7. EVOH Processing Techniques

  • Co-extrusion (Film and Blow Molding)

  • Sheet Extrusion (Thermoforming)

  • Injection Molding

  • Blow Molding for Bottles

  • Requires tie-layers (adhesives) for bonding with polyolefins


8. EVOH Recycling & Sustainability

  • EVOH is not used alone, typically part of multilayer packaging

  • Can be recycled with proper layer separation

  • Supports sustainable packaging by reducing the need for metal or glass

  • Brands using EVOH can meet eco-compliance and extended shelf life targets


9. Global EVOH Suppliers and Manufacturers

India:

  • Kuraray India

  • Eval Europe (Distributors)

  • Local converters using imported EVOH resin

International:

  • Kuraray Co. Ltd. (Japan, leading producer of Eval™ EVOH)
