Adhesive Tape Terminology

Single-Sided Tape: For single-sided tapes, the backing can be comprised of a variety of flat web-based materials,

such as film, paper, foil, fabrics, or foam. In many instances, the backing is treated with a release coating to enable

surfaces can be bonded full surface and tension free. In combination with application advise, training
and possible audits, these tapes can be used in warranty applications up to 25 years.
Backings: A backing (or carrier) is a relatively thin, flexible, web based material. It can be made from various kinds of
materials, such as paper, film, foil, foam, fabrics, non-wovens, and laminates. Backings are often chosen due to the
function they fulfill, such as cushioning, dampening, maintaining a barrier, etc.
Release Liner: A release liner is mainly used with double sided tapes. Siliconized papers or films are the main types of
release liners. The optimal liner choice depends on the application. If die-cut ability is required, polyester liners are
preferable. If the tape is exposed to humidity, poly-coated papers are mainly used due to their dimensional stability.
For most applications, paper liners are the liners of choice.

Adhesion: Adhesion is the attraction force between adhesive and substrate, which depends on the adhesive, the
substrate, and the application conditions such as: application pressure, time period of pressure, and temperature

Cohesion: Cohesion describes the inner strength of an adhesive. It is relevant for applications where the force, in effect,
is parallel to the bonding area. High cohesion goes hand-inhand with high temperature resistance, low-edge picking,

pressure and for a short period of contact time. For most applications, tack is not relevant because time is required
to press the tape to the substrate. For applications such as flying splices in the paper and print industry, tack is an
important criterion. Tack also supports adhesion on rough surfaces. The thumb test is often used to characterize
an adhesive, even though it gives no indication of the adhesion or the overall tape performance.
