5 Things to Consider When Selecting the Proper Baling Wire for Your Cardboard Baling

5 Things to Consider When Selecting the Proper Baling Wire for Your Cardboard Baling

Cardboard balers are designed to compact boxes, and other bulk cardboard materials into manageable bundles that can be recycled or disposed of. By eliminating the clutter, you can free up space as well as reduce fire hazards. However, selecting the proper baling wire is crucial for your cardboard baling. You want to make sure that baling wire can withstand the elements and keep them secure during transport. Cheap baling wire can save you money but in the long run, it may end up costing you more because of damage, breakage, and corrosion to your equipment. Therefore, always select high quality and reliable baling wire.

Following are 5 things to consider when selecting the proper baling wire for your cardboard baling:

1. Choose the Proper Type

Not all baling wires are the same. Furthermore, different baling machines require different types of baling wires. So, it is recommended that you figure out what type of wire you need for your cardboard baler. The manufacturers usually recommend a certain type of wire for the machine when you purchase the baler. So, all you need to do is read the instruction manual. However, if you have purchased a used baler, then you may not have the instruction manual. In that case, contact the seller and ask what type of wire they use in their machine. Never purchase a baling wire blindly.

2. Check the Gauge

The way a baling wire is made determines its quality; so, when you buy the baling wire, be sure to check the wire&#;s gauge. The gauge is basically the diameter and thickness of the wire. If the gauge is smaller and the wire is weak, it will snap under pressure, causing the compressed material to expand. So, do your research before making your purchase. You can expect baling wires from renowned companies to be of good quality.

3. Check the Tensile Strength

The tensile strength is the ability of the baling wire to withstand pressure and tension. Compressed materials want to expand back to their original size when they are tied together. It is the job of the baling wire to endure considerable amount of pressure and keep the materials compressed. So, the correct tensile strength is crucial as it keeps the materials compressed and also ensures that the shape of the materials is maintained.

4. The Wire Ties Must Have the Right Balance

If you are buying single-loop or double-loop baling wire, then make sure that the wire ties have the right balance between being malleable enough to allow them to be tied tightly by hand and being stiff enough to allow you to easily push them through the slots.

5. Make Sure it is Twisted Properly (for Single Loop Bale Ties)

Single-loop bale ties contain several twists that create the loop. If the loop is not twisted properly, then they can become unraveled once the wire is under pressure. So, make sure that the wire is twisted properly. The loop size must also be consistent.

To choose the right baling wire for your requirements, review the following four factors:

1. Type of baler
2. Load strength and wire gauge requirements
3. Storage conditions
4. Cost considerations

Type of baler

Some baling machines will operate best with certain types of baling wire or a specific wire gauge range. To choose the right baling wire for your machine, determine which type of baler you have. In the recycling industry, vertical, horizontal, auto-tie, and two-ram balers are most common:

• Vertical balers take up little floor space, have smaller feed capacities, and generally require bale ties to be manually tied. The best types of wire for a vertical baler are single or double loop bale ties.
• Horizontal balers use more floor space, have larger feed hoppers, and are used in larger recycling and waste management operations. They are commonly semi-automatic or automatic baling machines; they begin operation automatically once their chamber is full, and they automatically tie bales. Boxes or stems (spools) of galvanized, high-tensile, or black annealed wire work best with horizontal balers. 
• Two-ram balers are horizontal balers that have an additional ram that produces denser, heavier bales than other balers. These balers are used in high-volume recycling facilities that handle challenging materials, such as tires or scrap metal.

Contact your baling machine manufacturer and read your baling machine manual to learn about the wire types and gauge sizes that work best with your baler machine.

Load strength and wire gauge

The type of material and the size of bales determine which wire gauge should be used. Thicker wire diameters (smaller wire gauges) have higher load and tensile strengths. Tensile strength is the force a material can withstand before breaking, and load strength is the weight a specific wire can hold without breaking.

When choosing a wire, calculate the weight of the bale and the combined load strengths of the wires you&#;re using. The total load strength of all baling wires should exceed the weight of the bale. Here is a chart of bale weights for common recyclables and regular (not high-tensile wire) load strengths:

Storage conditions

Storage duration and conditions also influence wire selection. Baling wire rusts when exposed to wet, humid, or chemical storage conditions, or when it is used outside. To improve the lifespan of baling wire, choose a wire that is appropriate for your storage conditions.

For bales that will be stored briefly, regular baling wire or black annealed wire are the best choices. Black annealed wire is coated in wax or oil, which endows it with moderate resistance to rust and corrosion. Black annealed wire will rust if used outdoors or exposed to damp conditions.

For outdoor applications or long-term storage, galvanized wire is the best option. Galvanized wire is protected from rust and corrosion by a sacrificial layer of zinc, provided by the galvanization process. Galvanized wire can resist rust for between 20&#;50 years (often longer) depending on its galvanization class and the conditions it is exposed to. We provide both Class 1 and Class 3 galvanization on our wire products, with Class 3 Galvanization offering the highest level of rust and corrosion resistance.

Cost considerations

Baling wire costs can add up. Select the most economical option that satisfies load strength, baler, and storage requirements to keep baling wire costs low.

For bales stored in climate-controlled facilities or bales that only require short-term storage, bright (uncoated) double loop bale ties are both less expensive and more aesthetically pleasing than other options.

If you&#;re using an automatic baler, the elongation properties of black annealed wire should also be calculated. The annealing process improves a wire&#;s elongation (the percentage of a wire&#;s length it can be stretched without breaking). Calculate the elongation and load strength requirements of your operations and ensure you are using your baling wire as efficiently as possible to further minimize costs.

Some other ways to save on baling wire include:

• Recycle used baler wire. Not only does this allow recyclers to double down on their commitment to the circular economy, but selling scrap baling wire can help offset operating costs.

• Buy in bulk. We offer competitive prices for bulk orders. If your baler is compatible, it is cheaper to buy stem wire in bulk than it is to buy an equivalent amount of box wire.
