Net wrap has become one of the most widely used bale-wrapping materials in modern agriculture. Compared with traditional baling twine, net wrap offers faster wrapping, stronger bale integrity, and better protection against weather exposure. This article explains what net wrap is made of, how it works on round balers, and why more farmers in the United States, Canada, Australia, and Europe rely on it for hay, straw, and silage production.
What Is Net Wrap?
Net wrap is a high-strength polyethylene mesh designed to secure round bales of hay, straw, or silage.
It is made using HDPE or LLDPE plastic tapes that are stretched, slit, and knitted into a uniform open-mesh fabric.
Key characteristics include:
- High tensile strength
- Consistent mesh structure
- UV-stabilized materials
- Lightweight but durable design
- Compatibility with most round balers
Net wrap is produced in various widths—most commonly 48″, 51″, 64″, and 67″—and in roll lengths ranging from 7,000 ft to 9,000 ft, depending on the baling requirements.
What Is Net Wrap Made Of?
Most commercial net wrap is made from:
- HDPE (High-Density Polyethylene)
- LLDPE (Linear Low-Density Polyethylene)
These materials are chosen for their:
- Strength-to-weight ratio
- Resistance to tearing
- Performance under tension
- UV durability during outdoor storage
The production process includes extrusion, stretching, slitting, knitting, and winding, ensuring the final roll maintains stable width and consistent strength across its entire length.
How Net Wrap Works on a Round Baler
Once the bale reaches its preset diameter inside the baler chamber, the wrapping system automatically feeds the net wrap into the bale.
1. Feeding and Start of Wrap
The net enters the bale chamber and catches onto the rotating bale surface.
2. Controlled Tension Wrapping
The baler applies controlled tension to the net so it wraps tightly and uniformly around the bale.
3. Edge Protection
Quality net wrap covers the bale from edge to edge, preventing material loss and protecting the bale shape.
4. Automatic Cutting
After the designated number of wraps—typically 2–3 wraps per bale depending on crop type—the baler cuts the net and releases the bale.
This process is significantly faster compared to twine wrapping, reducing baling time and fuel consumption.
Why Farmers Use Net Wrap Instead of Twine
Search demand shows high interest in “net wrap vs twine” and “is net wrap better than twine?”.
For most operations, the answer is yes, mainly because of:
• Faster Baling
Net wrap reduces wrapping time by up to 70%.
• Improved Bale Protection
A smoother, sealed surface sheds water more effectively.
• Better Shape Retention
Net-wrapped bales maintain density and resist expansion.
• Reduced Loss During Handling
Less leaf loss and fewer broken flakes when moving or feeding.
• Lower Spoilage Rates
Improved coverage helps minimize mold formation during storage.
How Many Wraps or Bales Per Roll?
Common farmer questions include “How many bales will a roll of net wrap do?” and “How much net wrap per bale?”
The actual number depends on:
- Bale diameter
- Crop type (hay, straw, silage)
- Wraps per bale
A standard 67” × 8,000–9,000 ft roll typically produces:
- About 150–300 bales, assuming 2–3 wraps per bale
Silage bales require more wraps, while dry hay may need fewer.
How Long Does Net Wrap Last?
Because net wrap is UV-stabilized, it typically lasts:
- 12–18 months for outdoor-stored bales
- Longer if bales are sheltered or stacked strategically
High-density polyethylene and UV additives protect the mesh from sunlight, moisture, and mechanical wear.
Common Net Wrap Sizes and Applications
Popular sizes include:
- 48″ net wrap – small round balers
- 51″ net wrap – standard hay balers
- 64″ net wrap – 5×6 bales
- 67″ net wrap – large round balers
Used for:
- Hay bales
- Straw bales
- Bedding material
- Silage
- Forage stored outdoors
Practical Tips for Using Net Wrap
- Store rolls away from direct sunlight
- Keep the roll clean to avoid feeding issues
- Check baler settings for proper tension and brake pressure
- Use recommended wrap count for your crop type
- Inspect knives and rollers to avoid tearing
Proper handling prevents most issues related to net breakage or uneven wrapping.
Conclusion
Net wrap provides a reliable, efficient method for securing round bales across all major forage crops. Its strength, weather resistance, and time-saving benefits make it the preferred choice for farmers looking to protect bale quality and increase productivity.
For operations producing high bale volumes or storing bales outdoors, net wrap offers clear advantages over twine and remains one of the most effective bale-wrapping solutions on the market.
