Abstract
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.
Claims21
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;
- and
- a second edge face opposite said first edge face;
- wherein the substrate comprises a first major surface and a second major surface, and
- wherein 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.

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;
- and
- a second edge face opposite said first edge face;
- wherein the substrate comprises a first major surface and a second major surface opposite the first major surface, and
- wherein a UV-polymerized pressure sensitive adhesive 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, wherein the non-contact treatment comprises exposure to an ultraviolet radiation source with radiant output at a wavelength of less than 200 nanometers.

A method of reducing tackiness of a substrate bearing an adhesive, said method comprising:
- providing a substrate comprising a first major surface and a second major surface, wherein 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 major surfaces by subjecting either or both of the upper and lower major surfaces to an ultraviolet radiation source with radiant output at a wavelength of less than 200 nanometers.
