Shipping labels completely cover what's underneath so corrugated boxes can be reused. Kraft material matches brown box color and makes new logos, addresses and messages on the labels appear to be printed directly on the box. Kraft color provides a printed on look. Labels are compatible with laser and inkjet printers and work with major internet postage service software. Label paper is made with a high percentage of recycled material and with a chlorine-free process. The labels are recyclable.
