Elkay vented lettuce bags are commonly used by supermarkets and produce stores to hold fresh lettuce. Since the bags are vented, they can prolong the freshness of the lettuce by allowing air to circulate through. The bags are made of strong and flexible co-extruded polypropylene and have a generous bottom gusset for additional storage. Printed 1 color, 1 side with “Eat 5 a Day” artwork.
