If you are searching for a 330mm silage film baler, you are looking for a machine that produces medium-sized round bales, the practical middle ground between small hand-handled bales and the big half-ton and one-ton formats. A 330mm film width is matched to bales weighing roughly 150 to 200 kg, a size that suits a great many working farms. What makes this class interesting is that Jummos offers three different machine types that all run 330mm film, so you can pick the one that fits how you like to work. This guide explains the 330mm film width and walks through those options.

Why 330mm Film Points to Medium Bales
Silage stretch film is produced in a range of widths, each one matched to a bale size. The wider the film, the larger the bale it wraps. At the narrow end, 250mm film is used for small bales of 50 to 120 kg. At the wide end, 750mm film wraps the largest one-ton bales. The 330mm film sits in the medium band, built for bales of around 150 to 200 kg.
This is why film width is such a useful way to shop for a baler. If you want medium bales that are substantial enough to be efficient, yet still light enough to handle without the heaviest equipment, then a 330mm silage film baler is the class you are looking for. The film width points you straight to the right group of machines.
| Silage Film Width | Typical Bale Weight | Best Suited To |
|---|---|---|
| 250mm film | 50 to 120 kg | Small farms, compact bales |
| 330mm film | 150 to 200 kg | Medium bales, mixed operations |
| 500mm film | 500 to 600 kg | Commercial farms, half-ton bales |
| 750mm film | 950 to 1000 kg | One-ton bales, high volume |
Three Jummos 330mm Film Balers to Choose From
Unlike some bale sizes that map to a single machine, the 330mm medium-bale class gives you three distinct Jummos options. They all wrap with 330mm film and all produce medium bales, but they differ in machine type, capacity, and the way they operate. Here is how they compare.
| Model | Type | Bale Weight | Bale Size | Power |
|---|---|---|---|---|
| 9YCL-0.63 Combi | Combi baler wrapper (bales and wraps in one pass) | up to 150 kg | Φ630 x 650mm | 16.5kW electric |
| BalerPro 70 | Fully automatic hydraulic belt baler | 200 kg | Φ750 x 700mm | 11kW three-phase |
| 9YDB-0.7 | Electric bale wrapper | 150 to 200 kg | Φ700 x 720mm | 15kW electric |
9YCL-0.63 Combi Baler Wrapper
The 9YCL-0.63 is the combi option, which means it forms the bale and wraps it in one continuous pass with no separate wrapper needed. It produces neat bales up to about 150 kg at Φ630 mm, runs on a 16.5 kW electric supply, and moves quickly at 55 to 65 bales per hour. It is a strong choice if you value the simplicity and speed of an all-in-one machine.
BalerPro 70 Fully Automatic Hydraulic Belt Baler
The BalerPro 70 is the heavy-duty, fully automatic belt baler in this group. It produces larger 200 kg bales at Φ750 mm, runs a powerful 11 kW three-phase main motor with dedicated motors for every function, and includes features built for continuous commercial use, such as a double control system and an integrated leakage recovery device. It can strap with either inner film or net wrap, giving you flexibility across different crops and storage strategies. This is the machine for operations that want automation and durability at the medium-bale size.
9YDB-0.7 Electric Bale Wrapper
The 9YDB-0.7 is the electric bale wrapper option, producing 150 to 200 kg bales at Φ700 mm on a 15 kW electric supply, at 45 to 60 bales per hour. It suits farms that have reliable grid power and want a dependable electric machine in the medium-bale class.
“What I like about the medium-bale range is that we can genuinely match the machine to the person, not just the bale size. Some customers want the simplicity of a combi that bales and wraps in one go. Others are running a busy commercial operation and want the fully automatic BalerPro 70 with all its controls. The film width is the same across all of them, so the real question I ask is how hands-on the customer wants to be and what power they have available.”

The Film and Net Wrap These Machines Use
All three of these machines are built around 330mm silage stretch film, and because Jummos manufactures the film as well as the balers, the two are matched from the start. The exact net wrap varies slightly by model, running around 0.72m to 0.75m in width, and the BalerPro 70 can also run an inner barrier film for extra oxygen protection on high-value silage.
Sourcing the 330mm film and net wrap together with the machine avoids the common problem of trying to match film from one supplier to a baler from another, which often leads to poor overlap or a weak seal. If you want to understand the film side in more detail, our guide to agricultural silage film covers how the film protects your forage through storage.
Who a 330mm Film Baler Is For
A 330mm silage film baler suits farms that want a bale big enough to be efficient but light enough to stay flexible. The 150 to 200 kg medium bale is easier to move and store than a half-ton bale, yet holds far more forage than a small compact bale, which makes it a versatile choice for mixed operations.
It is a good fit for medium-sized dairy and beef farms, for farms that handle bales with lighter loaders or by hand for smaller batches, and for operations that want a manageable bale for both their own herd and occasional sale. Once wrapped, these medium bales feed neatly into a total mixed ration workflow when it is time to prepare feed.
If a 330mm machine is not quite the right size, the same logic applies across the range. Step up to 500mm film for half-ton bales, or down to 250mm film for compact bales. You can compare the full lineup on our baler wrapper page, or contact the Jummos team to confirm which of the three 330mm machines best fits your operation.
Frequently Asked Questions
What is a 330mm silage film baler used for?
A 330mm silage film baler is used to produce and wrap medium round bales weighing around 150 to 200 kg. The 330mm film width is matched to this medium bale size, which is efficient to produce yet still manageable to handle. In the Jummos range, three machines run 330mm film: the 9YCL-0.63 combi baler wrapper, the BalerPro 70 fully automatic belt baler, and the 9YDB-0.7 electric bale wrapper.
Which 330mm film baler should I choose?
It depends on how you want to work. Choose the 9YCL-0.63 if you want a combi machine that bales and wraps in a single pass for simplicity and speed. Choose the BalerPro 70 if you want a fully automatic, heavy-duty belt baler with advanced controls for continuous commercial use, and the flexibility to use inner film or net wrap. Choose the 9YDB-0.7 if you have reliable grid power and want a dependable electric bale wrapper. All three produce medium bales wrapped in 330mm film.
What bale size does a 330mm film baler produce?
The three Jummos 330mm machines produce medium bales in the 150 to 200 kg range. The 9YCL-0.63 makes bales up to about 150 kg at Φ630 mm, the BalerPro 70 makes 200 kg bales at Φ750 mm, and the 9YDB-0.7 makes 150 to 200 kg bales at Φ700 mm. All are wrapped in 330mm silage film.
Can I buy the 330mm film with the baler?
Yes. Jummos manufactures both the balers and the silage film, so you can order the 330mm film and the matching net wrap together with any of these three machines as a single package. Buying the machine and consumables from the same manufacturer ensures they are correctly matched, which gives a cleaner, tighter seal than combining film and machine from different suppliers.
