The thickness (as of a sheet of paper) measured under specific conditions.

The ability of a tape to resist damage when a force is applied evenly and perpendicularly to the surface of a tape.

Adhesion between the sheets of the plies of rolls of coated material, usually due to extreme conditions of pressure, temperature, or humidity.

Penetration through the tape of a coloring material (paint, etc.) onto the surface to which the tape is applied.

An occlusive coating applied to the non-pressure sensitive side of a porous backing such as paper in order to provide a satisfactory surface that the pressure sensitive adhesive can contact when the tape is wound into a roll.

A relatively thin flexible material to which the adhesive is applied.   Theoretically any material that is reasonably flat, thin, and flexible can be used as a tape backing.

The specific adhesion of a pressure sensitive adhesive to a face material or an anchor coat.

The conveyance of adhesive from its normal position on the tape backing to a surface to which the tape was attached, either during unwind or removal.

Adhesive that is pulled away from the tape upon removal and remains on the surface to which it has been applied.

The bond produced to the backing of the same tape or another tape backing.

Exposure in a chamber to ultraviolet light, heat, and water whereby the effect of outdoor exposure on a tape can be approximated.
