We’ve heard of candy in a resealable pouch. But a reclosable candy bar wrapper? Mars has found a way to mix convenience and portion control with its new Snickers King Size bar, which contains two candy bars wrapped in a twistable film that allows consumers to eat one bar now, and save the other for later. Once they twist the wrapper closed, it stays closed until they open it again. (Graphic design: Mars, www.mars.com; Structural design, printing: Bemis, www.bemis.com)
