Just a side note, I find this interesting, as we are also in plastics.
We use the same terminology, with vastly different meaning. (also pellets) For us:
- gaylord → big cardboard box, about 4’ x 4’ x 4’, 1100lbs - 1500lbs
- supersack → big nylon bag with a dispenser on the bottom, probably 1500lbs to 3000lbs
I guess it might be related to how people will measure with what they know.
I think @josecgomez posted this one once before:
