(57) A composite strip for preparation of a substrate edge for application of labels is
disclosed. The composite strip comprises an elongated carrier web having an upper
surface and a lower surface with the lower surface having a pressure sensitive adhesive
backing covered with a removable release sheet. A high tensile strength film, such
as that sold under the trademark "Mylar" by DuPont, is directly bonded to the upper
surface of the carrier web by a further adhesive. This film provides a receptor surface
for receiving labels. The film is of a width equal to or less than the width of the
carrier web and of a width to receive a label therein. This composite strip has proven
useful in preparing a substrate, such as an existing file folder tab or the edge of
an x-ray jacket for the subsequent application of a discrete series of labels applied
about the edge of the substrate. Such discrete series of labels may also be applied
to the composite strip before its application to the edge of the substrate. The composite
strip is also advantageously used in combination with a tab extension to provide an
add-on tab assembly.
