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.
Class A Die Cutting – a process using a male and femaleprecision die set, also known as "compound tooling".This type of tooling will produce the highest quality of cut with the least amount of burrs on the die cuts and the closest tolerances in the industry (+/- .001").
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).
Rotary Die Cutting – the process of using a cylindrical engraved hardened steel tool to cut materials at high speeds and close-tolerance cutting.Many layers of materials can be cut at one time, using different materials and cutting dies in registration to produce your most complex parts.
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.
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.
