Your choice of bale wrapping matters more than most people think
Whether you’re storing hay outdoors, indoors, or selling to customers, the type of wrapping you choose dramatically affects:
- Shelf-life
- Dry matter loss
- Mold resistance
- Weather protection
- Feeding efficiency
- Labor time
This guide breaks down net wrap, twine, and plastic wrapping (bale silage/wrap), helping you choose the right option for your climate, storage setup, and livestock needs.
1. Net Wrap: Fast, Clean, and Highly Protective
Net wrap has become the go-to wrapping option for large round bales — and for good reason.
Advantages of Net Wrap
✔ Shorter baling time
Net wrap reduces baling time by 30–50% compared to twine.
✔ Better moisture protection
The dense mesh:
- Sheds water better
- Keeps bale edges tighter
- Reduces spoilage on the outer layer
✔ Maintains bale shape
Great for stacking and transport.
✔ Less hay loss during handling
Edges don’t fray like twine-wrapped bales.
Disadvantages of Net Wrap
❌ More expensive
Costs 2–3 times more than twine.
❌ Harder to remove in freezing weather
Frozen net wrap can be frustrating during winter feeding.
❌ Environmental concerns
Plastic mesh must be disposed of properly.
Shelf-Life Impact
With outdoor storage, net wrap typically reduces surface loss by 5–10% compared to twine.
2. Twine: Budget-Friendly and Time-Tested
Twine (sisal or plastic) is the oldest and simplest wrapping method, still widely used by small operations.
Advantages of Twine
✔ Cheaper upfront
Twine is the least expensive wrapping option.
✔ Easier to cut and remove
No fighting frozen layers.
✔ Biodegradable options available
Sisal twine naturally breaks down.
Disadvantages of Twine
❌ Longer baling time
Up to 2 minutes longer per bale.
❌ More outer-layer spoilage
Looser bale edges mean:
- More rain penetration
- Greater dry matter loss
- More bleaching
❌ Weaker weather resistance
Especially in windy, wet climates.
Shelf-Life Impact
Twine allows 10–20% more spoilage on outdoor bales compared to net wrap.
3. Plastic Bale Wrap (Bale Silage / In-Line Wrapping)
Plastic wrapping creates an air-tight seal, essentially turning hay into baleage or silage. This is NOT dry hay — this is fermented forage.
Advantages of Plastic Wrapping
✔ Excellent moisture protection
Perfect for high-rainfall regions.
✔ Allows baling at higher moisture
Can safely wrap hay at:
- 30–60% moisture for baleage
- 18–25% moisture for wrapped dry hay
✔ Longest shelf-life of all options
Wrapped bales can last 12 months or more with minimal loss.
✔ Reduced dust
Great for horses with respiratory sensitivity.
Disadvantages of Plastic Wrapping
❌ Very high material cost
Multiple layers of film are required.
❌ Special equipment needed
You must have a bale wrapper.
❌ Risk of punctures
A hole in the wrap can ruin the fermentation.
❌ Heavier bales
Higher moisture = heavier handling weight.
Shelf-Life Impact
Properly wrapped baleage can lose less than 5% dry matter, making it the best preservation method.
4. Outdoor vs. Indoor Storage: The Hidden Factor
Wrapping performance depends greatly on storage environment.
Outdoor Storage
- Net wrap performs significantly better than twine
- Plastic wrapping performs best of all
- Twine-wrapped bales can lose up to 30% in high-rainfall climates
Indoor Storage
- All three types perform well
- Twine becomes more viable
- Net wrap still reduces fraying and handling loss
5. Best Practices for Maximizing Hay Shelf-Life
Regardless of wrapping type:
✔ Store on gravel or pallets
Prevents bottom rot.
✔ Keep weeds trimmed around storage
Promotes airflow.
✔ Orient rows north-south outdoors
Reduces shading and moisture retention.
✔ Wrap bales as soon as possible
Especially for baleage — delays cause spoilage.
✔ Use multiple layers of plastic
6–8 layers for baleage, 4–6 for dry wrapped hay.
6. Which Wrapping Should You Choose? (Quick Guide)
Choose Net Wrap If:
- You want fast baling
- You store outdoors
- You care about appearance and uniformity
- You sell hay commercially
Choose Twine If:
- Budget is a priority
- You store mostly indoors
- You want easier winter feeding
- You use smaller operations or older balers
Choose Plastic Wrap If:
- You live in a rainy climate
- You make baleage
- You want the longest shelf-life
- You have wrapper equipment
FAQ
Does net wrap make hay last longer?
Yes — especially outdoors, where it reduces weather-related losses.
Is sisal twine better than plastic twine?
Sisal is biodegradable but weaker; plastic is stronger but non-degradable.
Can horses eat baleage?
Yes, but only when fermented correctly and mold-free.
Does plastic-wrapped hay spoil if punctured?
Yes — even small holes can ruin the fermentation.
Conclusion: Wrapping Your Bales Right Protects Your Investment
Twine, net wrap, and plastic each have strengths and weaknesses — but all impact hay quality, storage life, and labor. Choosing the right material for your operation ensures better forage, healthier livestock, and less waste.
Your hay is valuable — wrapping it properly preserves that value.
