Yellow Jacket Case Study – Orbital Stretch Wrap System

Perfect for oversized, oddly shaped, palletized loads

A leading manufacturer of A.S.M.E & standard tank heads, hot-formed tank heads, cones, manways and rolled shells, needed a way to wrap heavy, odd-shaped loads while the pallet remains on the forklift. Varying in size and material, tank heads measure from 8 5/8” diameters to 16’ diameters. Each day the company ships roughly 27,000 lbs of product in about 40 pallets, throughout the United States and Mexico.

Challenges Presented

The company was hand wrapping pallets which required 3 employees and increased risk to employee safety since workers would pass under the heavy load to pass the flm. In addition, flm rolls are heavy and can cause back injuries. In contrast, Muller’s Yellow Jacket orbital stretch wrapper requires only one employee to wrap the same loads in a fraction of the time. It also allows for a more uniform tension and wrap – further ensuring a consistently secured load.


To meet high wrapping demands, the company runs its Yellow Jacket 6 hours per 24hr time period without much delay. The Yellow Jacket orbital stretch wrapper is available in manual or semi-automatic. The 87M requires a footprint of only about 8’x9’ and runs on 110VAC- making it easy to install in most any plant. It also wraps a standard pallet size up to 68” diagonal.

The purchase of theYellow Jacket 87M has resulted in:

  • 30% savings in costs
  • labor and time savings
  • increased machine reliability
  • improved load containment process
