For more than 30 years, recy-clers have realized tie benefits of balers with automatic wire-tie systems, or auto-ties. Such systems reduce labor costs because they don't need workers to manually tie wire straps around bales. Auto-tie manufacturers frequently boast that their systems are "hands-off" operations that require only someone to haul away the finished bales. Fewer people involved in the baling process also reduces the potential for injury. Auto-ties lower processors' material costs by using baling wire more efficiently. And they create tighter, denser bales, which is a plus for scrap companies that ship overseas. "To get as much material as possible in 40-foot overseas containers, you need really square, compacted bales," one baling wire distributor says. "Auto-tie machines have become extremely popular because you get more compaction, a bale that's more of a cube, and a lot more weight per square foot in the containers."
