It is easy to find low-priced hay net wrap today. A few clicks in a search engine returns a list of manufacturers selling at surprisingly low prices, with easy delivery and attractive discounts. You can even buy directly from factories producing both net wrap and agricultural machinery. Wholesale purchases usually come with further price cuts, which makes it tempting to buy in bulk and head straight back to the field.
The real question, though, is what you are getting for that price. Will the hay you worked so hard to grow actually be protected, through heavy rainfall, snow, and long exposure to the sun? Few things are more discouraging than walking out to a meadow and finding dozens of bales with their net wraps torn open after a spell of bad weather.
Cheap net wrap usually comes at the cost of lower tensile strength, poor UV resistance, and unreliable coverage. This guide covers how to judge quality before you buy, how to fix the problems that come up during wrapping, and how to remove net wrap safely at feeding time.
Why Quality Matters in Hay Net Wrap
High-quality hay net wrap is more than packaging. It is the protection standing between your crop and the weather. Manufacturers building a reputation invest in high-grade materials, modern production technology, and strict quality control, so that every roll performs consistently in the field. A good manufacturer can still be affordable; what they will not do is cut the specification to reach a headline price.
The economics are worth thinking through. Net wrap is a small share of the cost of producing a bale, but it determines whether that bale survives storage. Saving a little on the wrap and losing part of the bale is a poor trade, and it is one farmers usually discover months later when the bale is opened.
Key Criteria for High-Quality Hay Net Wrap
- Strong bale holding power. Quality net wrap secures both round and square bales firmly, maintaining shape and density through storage and transport.
- Full bale coverage. The wrap should cover the entire width of the bale, including the shoulders, to prevent crop loss and keep the bale tight. Partial coverage at the ends is one of the most common failure points.
- Silage quality preservation. Good net wrap helps maintain feed quality by holding the bale tightly, which limits the air trapped inside. When opened, the feed should be fresh rather than blackened or rotten.
- High bale density. Premium wraps can handle dense bales of up to 700 kg/m³, which supports better fermentation and reduces spoilage.
- Easy handling and storage. Quality wraps are easier to apply, store, and remove, which saves labour and time in the field.
- UV and weather resistance. Look for strong UV stabilisation. Inferior wraps can degrade after only a few months of sun exposure, while quality wraps hold their integrity for a full season or longer.
- Consistent mesh and stretch. Uniform mesh size and controlled stretch give even coverage and far fewer breakages during wrapping.
One point deserves emphasis. Net wrap holds the bale’s shape, but it does not create an airtight seal on its own. For silage, net wrap is applied first and the bale is then wrapped in layers of stretch film, which is what excludes the oxygen. The two materials do different jobs and, for silage, both are needed.
Hay Net Wrap Compared With Twine
Net wrap is faster to apply than traditional twine, holds bales more firmly, and generally results in less dry matter loss, with wrapping time reduced substantially on most machines. Twine remains cheaper per bale and is still perfectly reasonable for dry hay that will be stored under cover and fed quickly.
If you are weighing the two properly, our dedicated comparison of twine versus net wrap efficiency goes through the trade-offs in detail.
Common Net Wrap Problems and How to Solve Them
Even good product causes trouble if the machine is not set up or maintained properly. Most wrapping faults trace back to the baler rather than the roll.
| Problem | What to Check |
|---|---|
| Net wrap will not cut cleanly | Sharpness of the cutting blade, brake adjustment, and the feed rollers. Use the adjustment strip if the machine has one. |
| Net tears during wrapping | The cutting knife lock. Always stop the machine fully before making any adjustment. |
| Net not stretching properly | Roller core installation. On balers with axle mounts, secure the roller base properly and pull the net evenly across both sides. |
| Loose yarns from faulty cutting | Roller core installation again, then adjust the brake bar or feed roller. |
| Net hanging loosely on the bale | Whether the bale is forming properly round, then adjust net tension. |
Removing Hay Net Wrap the Right Way
For many workers, removing net wrap is among the most tiring jobs on the farm, particularly with low-quality wrap that sticks, tears unevenly, or frays. Choosing good wrap at the outset makes removal noticeably faster and cleaner.
A simple method uses a bale fork.
- Insert the fork into the bottom of the bale at roughly a 20 degree angle, so the bale can be lifted over the feeder without detaching.
- Find the end of the net wrap and tuck it securely under the top of the bale.
- Tilt the fork to about 30 degrees, locate the starting point of the wrap, and begin unwrapping in a circular motion.
- Loop around the bale until all of the net wrap comes away cleanly.
Always Remove the Net Before Feeding
This is worth stating plainly, because it is a genuine and avoidable animal health risk. Net wrap is not digestible. If cattle ingest pieces of it along with their feed, the material can accumulate in the rumen and cause impaction, which is serious and expensive to treat.
The practical rules are simple. Remove all of the net wrap before the bale goes into a feeder or a mixer, not partway through. Check that no fragments have been left clinging to the underside of the bale. And collect the removed wrap rather than leaving it in the yard or the field, where it can be picked up later by animals or by a machine. A few extra seconds at the feeder is cheap compared with a veterinary bill.
Additional Tips for Choosing the Right Net Wrap
- Check UV ratings. Look for at least 12 months of UV resistance, ideally tested in conditions similar to your own climate.
- Verify roll length and weight. Cheaper rolls sometimes contain less material than the label suggests, which changes the real cost per bale.
- Look for reinforced edges. These prevent tearing at the shoulders during application, which is where most failures start.
- Match the width to your baler. The net must cover the full bale face. A roll that is too narrow leaves the ends exposed no matter how good the material is.
- Ask about manufacturer testing. Reputable manufacturers test their net wrap in real field conditions rather than only in a laboratory.
Do Not Compromise Quality for Price
Low-priced hay net wrap is tempting, but it is often a false economy. A torn or poorly wrapped bale means lost feed, extra labour, and a slower season. Investing in quality wrap protects the work you already put into growing and cutting the crop, and keeps the nutritional value and shape of your hay intact for months.

Frequently Asked Questions
Does net wrap alone preserve silage?
No. Net wrap holds the bale’s shape and density, but it does not create an airtight seal, so oxygen can still reach the crop. For silage, the net wrap is applied first and the bale is then wrapped in several layers of stretch film, which provides the oxygen barrier that fermentation depends on. For dry hay stored under cover, net wrap on its own is generally sufficient.
How long should net wrap last outdoors?
Look for wrap rated for at least 12 months of UV resistance, which should carry a bale through a full storage season. Actual life depends on how strong the sunlight is in your region and how the bales are stored. Poor quality wrap can begin breaking down after only a few months of sun exposure, which is when farmers discover that the saving on the roll cost far more in spoiled feed.
Why does my net wrap keep tearing during wrapping?
Tearing usually points at the machine rather than the roll. Check the cutting knife lock, the sharpness of the blade, the brake adjustment, and whether the roller cores are correctly installed. Uneven tension across the width is another frequent cause, so make sure the net is pulled evenly on both sides. Always stop the machine completely before making adjustments.
Is it dangerous if cattle eat net wrap?
Yes, and it should be treated seriously. Net wrap is not digestible, so pieces ingested with feed can accumulate in the rumen and cause impaction, a condition that is difficult and costly to treat. Always remove all net wrap before a bale goes into a feeder or mixer, check for fragments left on the bale, and collect the used wrap rather than leaving it where animals can reach it.
