METHODS OF MAKING DETACKIFIED ADHESIVE ARTICLES

摘要

Methods of reducing tack of edge faces of a roll of an adhesive coated substrate. The method includes reducing tack of the edge faces by subjecting the edge faces to a radiation source with radiant output at a wavelength of less than 200 nanometers.

1. A method of reducing tackiness of an edge face of a rolled substrate, said method comprising:
providing a rolled substrate comprising:
a first edge face; anda second edge face opposite said first edge face;wherein the substrate comprises a first major surface and a second major surface, andwherein an adhesive coating is disposed on either or both of the first major surface and the second major surface; and reducing the tackiness of either or both of the first and second edge face by subjecting either or both of the first and second edge faces to a non-contact treatment comprising an ultraviolet radiation source with radiant output at a wavelength of less than 200 nanometers.
