Getting the best from double sided tape
Bonding can be a challenge in almost every industry in situations where different materials need to be bonded. In addition, modern design concepts require high-tech materials to be bonded without affecting their special structures or properties. This is where double-sided adhesive tapes solve common mounting and fixing issues found in many production processes.
When bonding two surfaces using a double-sided tape, one side of the tape is positioned and fixed onto a surface A applying pressure. Once in place, the release liner of the tape is removed, and the surface B can be placed onto the open side of the tape and pressed into place with force being attached equally to ensure a good fit.
When a smaller object is being placed onto a flat surface, it is normally more effective to first attach the tape to the item being stuck in place. This reduces the amount of tape that needs to be used and helps to ensure that the item is positioned correctly.

A carrier is a thin backing on which the adhesive is spread. This carrier could be made of one of several materials: paper, film, fabric, acrylic foam, foil, or non-woven fibers. All double-sided tapes have a carrier which also helps further strengthen the bond. The choice of double-sided tape with a specific carrier depends on the application as each material brings particular properties to the tape.
Double-sided tape has adhesive on both sides of a carrier, allowing each surface to bond securely to the tape. The tape’s carrier also provides additional structural support. Adhesive transfer tape, however, has no carrier and just relies on the strength of the adhesive to form a bond. In return it offers an increased conformability and wetting performance.
Our extensive track record has allowed the experts at tesa to test our adhesive tapes against other types of bonding systems over many years. And based on our experience, the advantages of double-sided tapes are clear when meeting the challenges of today’s complex, optimized production processes. For example, double-sided tapes can greatly reduce common health risks related to liquid glue solutions and can be easier to handle. Moreover, double-sided tapes can even carry more weight than using regular screws in certain scenarios and provide more design freedom in manufacturing processes.
Double-sided tapes are used in many applications in a range of industries. Some are ideal for bonding to flat smooth surfaces such as glass, metal, and non-embossed plastics. Others are ideal for rough, irregular surfaces. All tapes generally offer a good temperature resistance, and they are easily integrated into current production lines. Double-sided tapes can absorb shocks and vibrations and are relatively easy to remove, if needed.
tesa® double-sided adhesive tapes provide strong hold on various surfaces, even for heavy duty applications. Many of our products can be removed easily and without leaving any residue, when needed. Over the last decades we have developed a broad range of double-sided tapes that can be debonded in different ways, e.g. by peeling, by applying solvents or by stretching (tesa® Bond & Detach). As debonding is becoming increasingly important we are constantly developing new methods. Please contact us to learn more.
