All About EVOH (Ethylene Vinyl Alcohol): Types, Uses, Manufacturing, Market, Recycling, and More
1. What is EVOH Plastic?
EVOH stands for Ethylene Vinyl Alcohol. People know it for being a top-notch barrier plastic—it’s fantastic at keeping oxygen and other gases out. You’ll find EVOH in everything from food packaging to car parts to medical wraps. Bottom line: if you need to protect something from air or keep it fresh longer, EVOH is probably in the mix. This isn’t some generic plastic; it’s what companies choose for food, medicine, or anything that needs to stay shelf-stable.
Why it stands out:
- Almost no oxygen or aroma gets through
- Holds onto flavors
- Lightweight, still tough
- Perfect fit for multilayer packaging
- Resistant to a bunch of chemicals
- Big in food and medical packaging
2. Types and Grades of EVOH
You’ll mostly see two main categories:
Virgin EVOH: Made from new, raw ingredients—used for stuff where quality really matters, like food and meds.
Reprocessed EVOH: Made from recycled factory waste, and goes into less sensitive things.
Main forms EVOH comes in:
- Film Grade: Flexible packs, like snack wraps
- Sheet Grade: For sturdy trays or tubs
- Extrusion Grade: Multilayer packaging
- Blow Molding Grade: Bottles and containers that need to block gases
- Pipe and Tank Grade: Automotive and industrial tanks
Common grades you’ll hear about:
- High Barrier
- Flexible Packaging
- Food Contact
- Medical
- Automotive
- Thermoforming
3. Where’s EVOH Used?
Honestly, it’s everywhere:
- Food: packs for meat, cheese, sauces, vacuum bags
- Pharmaceuticals: blister packs, pill wraps
- Automotive: fuel tanks and pipes
- Healthcare: sterile fluid bags, wraps
- Cosmetics: tubes or bottles for creams and lotions
- Industry: chemical drums, protective layers
Most of the time, companies use EVOH as a thin barrier inside multilayer packaging alongside PE, PP, PET, or PA—so it does its job without overcomplicating things.
4. How’s EVOH Made?
Quick version:
- First, they react ethylene with vinyl acetate (copolymerization).
- Next, they turn vinyl acetate into vinyl alcohol (hydrolysis) to get those signature barrier properties.
- Then, they throw in stabilizers or additives and turn it all into pellets.
How they work with it:
- Co-extrusion
- Blow molding
- Film extrusion
- Thermoforming
- Injection molding
EVOH really shines as a barrier layer inside products built from several different plastics.
5. What’s Made from EVOH?
- Food wraps and films that keep oxygen out (think cheese, meat, etc.)
- Vacuum bags
- Fuel tanks in cars
- Medical trays and wraps
- Cosmetic packaging
- Beverage bottles with multiple layers
- Food trays made by thermoforming
- Big storage containers for industry
6. Is EVOH Biodegradable?
No, regular EVOH isn’t biodegradable. Still, since you only need a tiny layer for great protection, EVOH helps food last longer—which actually means less waste overall.
Eco-friendly points:
- Lighter packs save materials
- Less spoiled food to throw out
- Some recyclable layers are possible
- Longer shelf life helps cut down on preservatives
EVOH lets companies use fewer preservatives and keep packaging lighter, which is a win for sustainability.
7. How Do You Recycle EVOH?
You can recycle EVOH, but it has to be sorted out and processed the right way.
Basic process:
- Collect the plastic
- Sort and wash it
- Grind it up or shred it
- Reprocess it into pellets
What can you make with recycled EVOH?
- Industrial films or sheets
- Utility parts
- Non-critical plastic items
Most of the time, it gets the recycling code #7 (Other Plastics).
