Abstract: Pressure-sensitive adhesive-backed labels are carried adhesive back side down on a backing strip. The present method and apparatus completely removes each label from its backing material and then may relocate, manipulate, or hold the label by its adhesive back side before it is attached to a passing article. The apparatus may be arranged to dispense the labels along an axis parallel to the path of travel of the moving article or along an axis that crosses the path of travel of the moving article.

Abstract: A shipping label that also functions as a packing list comprises a packet having a self-adhesive feature for attaching it to a shipping package with the same security of nonremovability as a standard shipping label. The packing list forms which are under the covering layer of the packet are multilayer composites that stick to the carton when applied but leave the sticky layer when pulled away. The packing list form has a place for the shipping address. The covering layer for the packet is opaque with a clear window overlaying the shipping address area. A packet may contain a plurality of packing list forms stuck one on top of the other. When each packing list form is pulled up it leaves a nonstick film on the one below it.
