Slitting/Rewindingis a shearing operation that cuts a large roll of material into narrower rolls. There are two types of slitting: log slitting and rewind slitting. In log slitting the roll of material is treated as a whole (the 'log') and one or more slices are taken from it without an unrolling/re-reeling process.

Steel Rule Die Cutting

Steel Rule Die Cutting – the process of using a flat die made with wood and hardened steel rules.This process is best suited for lower quantity orders where raw materials come in sheet form only and thicker materials that can be cut with straight edges (e.g. 2" thick foams).

Subsequent Adhesion

The force required to remove a unit width of pressure sensitive tape from a standard panel after it has been in contact with a release liner for a given period of time.   This must be compared with the adhesion of the same tape that has  not been in contact with the release liner to determine the degree of loss of adhesion.

Surface Energy (Surface Wetting Ability)

The measure of surface tension in dynes.  The lower the surface energy of a substrate, the more difficult it becomes for an adhesive or coating to wet out that surface.

Tear Resistance

The force required to propagate a tear in a tape in a given direction after the tear has been initiated.

Thickness (caliper, gauge)

The perpendicular distance from one surface of either a tape, backing, or adhesive to the other, usually expressed in mils, thousanths of an inch, or millimeters.  This is usually measured under controlled slight pressure with a special gauge.
