Continue until you have affixed a label containing a row of asterisks, above which is a short red line or long red line. A short red line indicates a package separation, a long red line indicates a sack separation. When you affix the label immediately below a short or long red line, with asterisks visible on the top mailpiece, wrap the pile into a package. If the pile is not over one inch thick, wrap 1 rubber band around the short dimension or girth. From one to six inches thick, wrap a first rubber band around the long dimension, and a second rubber band around the short dimension or girth, forming a package.
Postal regulations specify putting the rubber band on the length before the girth.
Look on top label of the package for sack code at the right hand end of the 2nd line. It will consist of 1 or 2 letters. Find the sack label with an identical sack code. Place the package into that sack. If the red line is full-width, close that sack and start to fill the next.
