Film Savings Design Drastically Reduces Film Usage
With conventional wrappers (rotary arm and turntables) the film clamp is fixed at conveyor height and the wrap cycle must start at the bottom and get to the top as fast as possible, apply the top wraps, spiral down with a controlled overlap to contain the load and finish at the bottom with bottom wraps and clamping and film tail treatment of the load. However the typically 30 ft. or so of stretch film applied getting to the top is effectively wasted film.
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.
