Backing – A thin flexible material which the adhesive is applied to. This is also known as a carrier.

Backings help protect and transport adhesive. The thickness of the carrier can be crucial for converting and die cutting adhesive. A thicker, stiffer backing helps the product maintain its shape and stability.

Below is the construction of a double coated adhesive. The carrier is the middle piece of the construction.

There are several options for carriers depending on the materials used and the process involved. Adhesive can come on Polycarbonate, Polyester, PVC, and other carriers. 3M even produces a Conductive Polycarbonate carrier for electronics applications. This carrier has electrical properties that help protect static-sensitive components with electrostatic shielding and electrostatic decay.
