What baling wire is best for closed-door balers?
Closed-door balers feature a baling chamber that is completely sealed during compaction. They can be vertical or horizontal, and they can be automatic or manual. Baling wire choice isn’t determined by whether or not the baler’s chamber is sealed. Operations choose baling wire based on whether or not they have an automatic or manual tie baler, the recyclable materials they process, the desired bale density, and how bales will be stored.

Wire for automatic and manual closed-door balers
Manual balers require human intervention for tying bales after compaction. Automatic closed-door balers complete the baling process and only require human intervention for bale ejection.
Wire for automatic closed-door balers
Automatic closed-door balers (or auto-tie balers) use box wire or stem wire. Both are sold by weight and provide a continuous wire feed. Box wire comes in smaller quantities appropriate for most baling throughputs. Stems are much heavier. They are best for high-throughput closed-door balers
Wire for manual closed-door balers
Bale ties are compatible with manual closed-door balers. These pre-cut, looped wires come as double loop or single loop bale ties. Operators can easily thread and tie them around the bale. Since both types of bale tie work with closed-door balers, the choice between single and double loop comes down to material and preference.
Wire specifications by baler type and material
Your baler manufacturer will specify which wire gauges work best with your machine. Always follow manufacturer recommendations. Based on your baler’s orientation and the type of material you are processing, we recommend the following wire gauges.
Wire for horizontal closed-door balers
- Cardboard (11–13 gauge)
- Newspaper (12–13 gauge)
- Plastic shrink wrap (11–12 gauge)
- Other plastics (11–12 gauge)
- Foam (11 gauge)
- Expansive materials, such as tires (11 gauge)
Wire for vertical closed-door balers
- Cardboard (12–14 gauge)
- Newspaper and office paper (12–13 gauge)
- Plastic shrink wrap (13–14 gauge)
- Other plastics (12–13 gauge)
- Foam (11 gauge)
- Expansive materials, such as tires (11 gauge)
Wire types by bale density
Denser bales place more strain on the wire, while you can save money on baling wire by using higher gauge wire for low-density bales. When choosing a wire gauge, multiply a wire’s load strength by the number of wires your baler feeds. The total weight should exceed the weight of the bale. Check wire gauge and type recommendations with your baler manufacturer, then use the following chart to learn about our wire products’ load strength:

How to choose the right coating for your storage conditions
Choose your wire type based on how and for how long you will store your bales. Galvanized wire offers the best protection against corrosion. Its zinc coating provides long-lasting protection that maintains the wire's integrity over extended storage periods. We offer a thin Class 1 Galvanization for general use and a much thicker Class 3 galvanization for long-term storage in humid, chemical, and exposed environments.
Annealed wire has a wax coating that provides temporary corrosion resistance. This makes it an excellent choice for facilities where bales will be exposed to temporary moisture or some humidity for a short period.
Bright wire, such as our 9 gauge double-loop bale ties, lacks protective coating, which suits situations where bales will be processed quickly or where appearance matters more than longevity. It's particularly appropriate for client-facing bales or short-term storage scenarios.
