When a film consisting of high density polyethylene and about three percent polystyrene is run on an interfolding machine to produce interfolded sheets of the film for use as deli wrap, the film is completely and consistently cut in the machine into sheets that are entirely separated from adjacent sheets. In comparison, sheets made from film consisting of 100 percent high density polyethylene are not consistently completely separated from adjacent sheets.
