Polymeric films and paper webs are the most important backing materials for self-adhesive tapes.
The backing material of the tape determines its mechanical properties (like conformability, stiffness and tensile strength) as well as its application-related properties (like thermal stability, UV stabilization and optical properties). Choosing the best backing material is therefore crucial for the final tape application. This presentation will provide
an overview of different polymeric films and paper webs regarding their specific properties and some typical applications. It will also point out features of manufacturing and processing of the backing materials. Additionally, some aspects of cloth and non-woven backing materials will be discussed.
