Bale Net Wrap vs Twine — Which Is Better for Round Hay Bales?

If you bale hay or straw, you have two main options for securing round bales: net wrap and twine. Both do the job, but they do it differently — and the difference matters when you are baling thousands of bales per season and storing them for months. This article compares the two on the factors that actually affect your bottom line.

Baling Speed: 2–3 Revolutions vs 20+

The most immediate difference is cycle time. Net wrap secures a bale in 2 to 3 revolutions of the bale chamber, while twine typically requires 20 or more revolutions. On a busy harvest day, that time adds up fast.

For a contractor baling 500+ bales per day, net wrap can save several hours of field time per day compared to twine. That means more bales per shift, lower fuel consumption per bale, and less wear on the baler.

Bale Shape and Density

Net wrap covers the entire outer surface of the bale, creating a uniform cylindrical shape that holds its form during handling and transport. Twine, by contrast, wraps in narrow bands, which can allow the bale to bulge between the strings — especially with soft or leafy material like alfalfa.

A well-shaped bale stacks more efficiently, sits more stably on a trailer, and sheds water better. For operations that sell hay by the bale, consistent shape also matters for presentation.

Weather Resistance and Storage Losses

This is where net wrap has its clearest advantage. Because the net covers the full circumference of the bale, rainwater runs off the rounded surface rather than soaking in between twine bands. Research from multiple agricultural extension services has shown that outdoor-stored bales wrapped in net can have 5–15% less dry matter loss compared to twine-wrapped bales, depending on climate and storage duration.

For operations that store bales outdoors for several months — which is common in many regions — this reduction in spoilage can represent significant savings in feed value. A DLG-certified bale net wrap with verified UV resistance provides additional assurance that the net itself will not degrade during extended outdoor storage.

Cost Per Bale

Twine is cheaper per unit of material. A roll of twine costs less than a roll of net wrap, and the material cost per bale is lower. This is the main reason some operations still prefer twine, particularly for straw or low-value hay that will be used quickly.

However, when you factor in the full picture — faster baling speed (lower labor and fuel cost per bale), reduced storage losses, and better bale integrity — net wrap often costs less per ton of usable feed delivered to the animal. The economics depend on your specific situation: how many bales you make, how long you store them, and whether they are stored indoors or outdoors.

When Twine Still Makes Sense

Twine is not obsolete. It remains a reasonable choice in certain situations:

• Small operations baling fewer than 200 bales per year, where the speed advantage of net wrap is less significant
• Straw bales that will be used within a few weeks and stored under cover
• Operations where the baler is not equipped for net wrap and the cost of retrofitting is not justified
• Very dry climates where outdoor storage losses are minimal regardless of wrapping method

What to Look for in Bale Net Wrap

If you decide net wrap is the right choice, here are the specifications that matter most:

Tensile strength determines whether the net can hold heavy, dense bales without tearing. Our bale net wrap has a single yarn tensile strength of 5.8 kg (12.79 lbs) and a full-width tensile strength of 270 kg (595.25 lbs).

UV resistance is critical for outdoor storage. Our net provides 12 months of UV protection. For buyers evaluating suppliers, independent certification is the most reliable way to verify UV claims — our bale net wrap carries DLG certification from Germany, which independently tests UV resistance and tensile performance.

Width compatibility must match your baler. Standard widths include 1.05m, 1.23m, 1.25m, and 1.4m.

Mesh density affects coverage uniformity. At 9 g/m², our net provides consistent, even coverage across the bale surface.

Which Should You Choose?

Here is a simple decision framework:

• If you bale more than 500 bales per season and store outdoors → net wrap will likely save you money overall
• If you bale fewer than 200 bales per season and store under cover → twine may be more cost-effective
• If you sell hay commercially and bale presentation matters → net wrap
• If you are baling straw for bedding and using it within weeks → twine is fine

For most commercial hay operations, net wrap has become the standard because the reduction in storage losses and the increase in baling speed more than offset the higher material cost.
