Unimprinted - E-Flute corrugated tuck box is available with white material on both sides. If four color process printing is wanted in smaller quantities on boxes, Spot Mounting on the lid only is an affordable option. The paper is printed with the four color process and this is then spot mounted to the lid of the box. One inch tolerance is required on all four sides. Outside Tuck allows the box cover to extend over the outside front of the box. All box material is recyclable.
