The PRRA is a revolutionary design that uses a unique wrapping ring concept. The PRRA Rotary Ring style wrapper is able to start at the bottom of a load and finish at the top without having to return back down to the clamp fixed at the conveyor. This means that you can save an extra 30+ feet of stretch film while still applying the same required load retention wraps. The result is thousands of dollars in annual film savings compared to all conventional wrappers. The PRRA Rotary Ring is similar in concept to the Muller Octopus 505, Octopus 606 and Octopus 808 but cost 30% less.
