The Ultimate Guide to Choosing Cardboard Baling Wire

13 Jan.,2025

 

What gauge wire is best for baling cardboard?

The best wire gauge for baling cardboard depends on the type of baler and the size and weight of your cardboard bales. For horizontal balers, we recommend 11&#;13 gauge wire. For vertical balers, we recommend 12&#;14 gauge wire. For two-ram auto-tie balers, we recommend 10&#;12 gauge wire. Talk to your baler manufacturer, read your baler&#;s instruction manual, or talk to us to figure out the best baling wire for your machine.

Choose a wire gauge based on the tensile strength and load strength requirements of your cardboard bales. Your wire's load strength should exceed the weight of the bale&#;we suggest going with a heavier-duty wire with a higher load strength if there is any uncertainty.

Wire gauge is inversely correlated to wire diameter. The larger the diameter, the lower the gauge, and vice versa.

Best cardboard bale wire

We carry several wire options for baling cardboard. The best wire type for baling cardboard will also depend on storage conditions and duration. Here are some of the best options:

  • Single loop bale ties can be manually cut to different lengths to accommodate inconsistent bale sizes. They work with horizontal and vertical manual balers. We offer both black annealed and galvanized single loop bale ties. Galvanized bale ties offer enhanced abrasion resistance for baled recyclables that are often handled roughly.
  • Double loop ties go in auto-tie balers and come in pre-cut lengths. The double loop configuration accelerates the tying process, increasing productivity.
  • Black annealed wire feeds smoothly through high-volume automatic baling machines that are commonly used in cardboard recycling. The rust resistance of galvanized wire is not usually necessary since cardboard bales need to be stored in a dry environment.
  • Galvanized wire is less commonly used for baling cardboard. But if your bales require long-term storage, galvanization offers increased resistance to rust and corrosion to keep bales safe and secure.

Benefits of recycling cardboard

Most types of cardboard are recyclable. Some of the benefits of recycling cardboard include:

  • Conservation of natural resources
  • Reduced greenhouse gas emissions
  • Reduced landfill waste
  • Production of 50% less sulfur dioxide
  • Job creation in collection, sorting, and processing
  • Community engagement around environmental impact awareness

Trends in recycling and demand for sustainable practices are driving technological advancements in the field of cardboard recycling.

How is cardboard recycled?

The cardboard recycling process involves the following steps:

For more information, please visit Cardboard Baling Wire.

  1. Cardboard is collected from residential curbsides or at recycling drop-off points.
  2. The cardboard is taken to a recycling facility or paper mill for processing.
  3. The cardboard is separated from other recyclables such as plastic, metal, and paper.
  4. The sorted cardboard is compressed into bales.
  5. The bales are sent for repulping. Paper fibers are cleaned to remove contaminants.
  6. New cardboard and paper products are made from recycled cardboard fibers.

Cardboard baling tips

Which Wire is Right for Your Baler?

These are the most common types of balers used for baling cardboard, plastic, textiles, or other packaging materials. Found everywhere from distribution centers and manufacturing facilities to warehouses, recycling facilities, and hardware stores, these balers rely on single loop bale ties. 

Single loop bale ties are available in two types of wire &#; galvanized and black annealed. Galvanized bale ties, which make up 90% of the market, are silver and shiny (akin to a chain-link fence) and are clean and easy to handle. The black annealed bale ties are black in color and offer a bit more stretch, but they can be a bit oily and may rust when exposed to the elements. 

The lengths of single loop bale ties can range from 10&#; to 22&#;, and the wire diameters can be anywhere from 15 gauge to 11 gauge. This depends on the size and weight of your bales.

The next level up includes auto-tie balers. They are typically continuously fed with conveyor belts or air systems and do not require personnel to tie off the bales. These balers use either 50lb or 100lb coils of black annealed baling wire, commonly referred to as box wire or auto-tie wire, with most balers requiring 8 to 10 coils at a time. 

The wire used for these coils ranges from 10 gauge to 12 gauge, depending on the materials being baled and bale weights, and can handle 60,000 to 75,000psi in tensile strength. These coils are either placed on mandrels on the sides of the baler or are kept in a stand near the baler after the center punch-out on the boxes is removed.

The top-tier balers, such as two ram balers or open door horizontal balers, use baling wire on the stump, or carrier. These balers are incredibly versatile and can switch between materials quite quickly. 

The two ram balers use high tensile galvanized baling wire, needing only a single stump of baling wire at a time. The stumps can range from lbs to lbs in size, containing either 11 gauge or 12 gauge material. This wire can handle between 145,000 and 170,000psi in tensile strength.
