ABSTRACT:
The process for applying labels to articles by first adhering a limited portion of the label to the article and subsequently rendering additional portions of the label adhesive so that they will adhere to the article after the label is affixed to the article. The leading and trailing edges of the label may be bonded to the article or each other to affix the label to a container or other such article. The portions of the label between the leading and trailing edges may be either provided with an adhesive agent that is in a non-adhesive state or be formed from a label material which is not normally adhesive but can be rendered adhesive through an additional process step. For example, coated polyethylene film can be applied to a container by means of a hot melt adhesive and then subsequently heated to a temperature at which the polyethylene material becomes adhesive causing it to stick to the container. Other labeling materials can be printed with an adhesive that remains substantially non-adhesive until heated or activated by means of radiation, application of a chemical activating agent or by application of mechanical force.
