The crop baling industry is not standing still. Film formulations, baler technology, and the regulatory environment around agricultural plastics have all shifted meaningfully over the past decade, and the direction of travel is fairly clear.
For farmers, this matters in a practical way. The wrapping decisions that made sense five years ago may not be the most cost-effective ones today, and some of the changes coming through regulation are not optional. This is a look at where the industry is heading and what it means for the people actually making bales.
Film Is Getting Thinner and Stronger at the Same Time
The most consistent trend in agricultural film over recent years has been the pursuit of more performance from less material.
Multi-layer co-extrusion allows manufacturers to build film in several distinct layers, each doing a different job. One layer supplies tack and cling. Another supplies puncture resistance. Another carries the UV stabilizers. Because each layer is optimized for a single property rather than compromising across all of them, the resulting film delivers better performance at a lower total thickness than an equivalent single-layer product.
The commercial logic is straightforward. Thinner film means more metres per roll, fewer roll changes in the field, lower freight cost per bale wrapped, and less plastic to dispose of afterwards. The constraint is that thinning the film without the layer technology to support it simply produces a weaker film that tears, and the market is full of cheap products that have done exactly that.
The practical guidance for buyers has not changed: judge film on what it does in the field, not on the micron number on the box.
Plastic Waste Is Becoming a Regulated Problem
This is the change with the sharpest implications, particularly for farms selling into European markets.
Agricultural plastic waste has moved from being a nuisance to being a policy target. Extended producer responsibility schemes, collection obligations, and recycling requirements are tightening across a number of jurisdictions, and the direction is one-way.
Several things follow from this for the crop baling industry:
- Recyclability is becoming a purchasing criterion. Clean, single-polymer film is far easier to recycle than mixed or contaminated material. Buyers are increasingly asking about this.
- Collection infrastructure is expanding. Where organized agricultural plastic collection exists, it is generally cheaper and easier than farmers expect, and it will become the norm rather than the exception.
- Burning and burying are being phased out. Both remain common practice in many regions and both are increasingly restricted.
There is an efficiency argument here that gets overlooked. A durable film that lasts the full storage period without failing means less plastic used per tonne of feed preserved, and less waste generated. Buying a cheap film that has to be doubled up or replaced is worse environmentally as well as economically.
Automation Is Moving Down-Market
Combination baler-wrappers, which bale and wrap in a single pass, were once the preserve of large contractors. They are steadily becoming accessible to mid-sized operations.
The advantage is not just labour. Wrapping immediately after baling, rather than moving bales to a wrapping station first, closes the window during which aerobic deterioration is under way. Every hour a wet bale sits unwrapped, the sugars that fermentation depends on are being consumed by aerobic bacteria. Machines that eliminate that delay improve silage quality directly, not just convenience.
Our group company Jummos manufactures baler wrappers, and the demand pattern we see reflects exactly this: buyers who previously wrapped separately are moving to combination machines as the price gap narrows.
The Market Is Splitting Between Commodity and Specification
There is a widening gap between two kinds of buyer.
At one end, price-driven buyers treat film as a commodity and buy on cost per roll. At the other, buyers with real losses to avoid are specifying film properly: virgin resin, verified UV rating, defined layer structure, guaranteed length.
This split is worth understanding because it changes what “cheap” means. Film is a small fraction of the value of the forage it protects. A film that fails halfway through storage does not save money, it destroys a far larger sum in spoiled feed. The buyers moving toward specification are not paying more for the sake of it. They are calculating the cost of failure.
“The most useful shift we have seen in the industry is buyers asking better questions. Ten years ago the question was almost always price per roll. Now we get asked about resin grade, UV rating, layer structure, guaranteed length. Those buyers get better outcomes, not because they spend more, but because they buy the film that actually matches their storage conditions instead of the cheapest one on the shelf.”

What Has Not Changed
For all the movement, some fundamentals are fixed, and no innovation is going to alter them.
| Constant | Why It Will Not Change |
|---|---|
| Oxygen ruins silage | Fermentation is anaerobic. No film technology changes the biology |
| The seal must hold for the whole storage period | A puncture in month three undoes everything done in month one |
| Plastic must be removed before feeding | Rumen microbes cannot digest polyethylene, and it accumulates |
| Wrap quality cannot fix a bad crop | Film preserves what you put in it. It does not improve it |
Should You Upgrade?
A closing thought that runs against the grain of most industry commentary.
The newest machine is not automatically the right machine. If your existing baler produces bales of the density and consistency you need, and your existing film holds its seal through storage, then the industry moving forward does not oblige you to move with it. Replacing functional equipment because a newer model exists produces cost without return.
The questions worth asking are specific: Are you losing feed to spoilage? Is the wrapping stage a bottleneck at harvest? Are you buying film that keeps failing? Where the answer is yes, an upgrade earns its keep. Where the answer is no, the industry can innovate without you, and that is fine.
Silopak has manufactured silage film and bale net wrap since 2011 from virgin resin, exporting under our own brand and as an OEM producer for buyers worldwide.
Frequently Asked Questions
Q: Is thinner silage film worse than thicker film?
Not necessarily. Modern multi-layer co-extruded film can deliver equivalent or better performance at a lower thickness, because each layer is optimized for a specific property such as cling, puncture resistance, or UV stability. What matters is the layer structure and the resin quality, not the micron figure alone. That said, cheap film that has simply been made thinner without the layer technology to support it is genuinely weaker and will tear. Judge film on field performance and specification, not on thickness in isolation.
Q: Will agricultural plastic regulation affect my farm?
Increasingly, yes, particularly in Europe and in markets supplying European buyers. Extended producer responsibility schemes, mandatory collection, and recycling requirements are tightening, and practices such as burning or burying used film are being restricted. The practical implications are that clean, single-polymer film is easier to recycle, organized collection schemes are expanding, and buyers are starting to ask about recyclability as a purchasing criterion. The direction of regulation is consistent enough that it is worth planning for rather than reacting to.
Q: Are combination baler-wrappers worth it?
They are increasingly worth considering for mid-sized operations as prices come down. Beyond the labour saving, the real advantage is that wrapping happens immediately after baling rather than after the bale has been moved to a wrapping station. That delay matters: every hour a wet bale sits unwrapped, aerobic bacteria are consuming the sugars that fermentation depends on. Closing that window improves silage quality directly. Whether the machine pays for itself depends on your bale volume and your current labour cost at harvest.
Q: Should I replace equipment just because newer models exist?
No. If your current baler produces bales of the density and consistency you need, and your film holds its seal through the storage period, a newer model adds cost without adding return. Upgrade when you have an identified problem: feed being lost to spoilage, wrapping acting as a bottleneck during harvest, or film that repeatedly fails. Innovation in the industry is not an obligation to buy.
