Abstract
A process for steam-sterilizing label-bearing containers stacked with the labels in contact, without destroying the labels such as occurs if the labels are printed by thermal transfer for product-variable data. The process features laser-ablating imagewise the label to remove an ink layer so as to expose either a contrasting ink layer below, or a metal foil or polymer substrate. Such containers are then readily stacked on the labels and sterilized without thermal damage to the labels.
