Before the heat-sealed plastic and resealable zip lock style closure, any large quantity dry goods (like potatoes or dog food) were sold in a sack or bag that was sewn closed across the top.

Like any sewn thread that was left unsecured, if you pulled on the correct end it would "unzip." Trying from the wrong end only tightened the sewn thread into a knot.

Oh, I found this sample image
