You save it…especially when it comes to labor costs.
People are expensive, but they’re worth it, as long as their time is spent in productive activities. Stretch wrapping by hand, watching a load spin while it’s being wrapped, and climbing on and off a forklift to cut film or press “start” don’t qualify. Neither does the time it takes to move a load from the wrapper to a freestanding platform scale. All of that is time wasted and money lost.
