Pressure Sensitive Tape is an adhesive tape that bonds to a surface when pressure is applied, without the need for heat, moisture, or chemical activators. In picture framing, it is often used for mounting, securing, or masking purposes, but care must be taken to use archival-quality versions near artwork to prevent damage over time.

Overview

Pressure sensitive tape consists of a backing material, such as paper, polyester, or plastic film, coated with an adhesive that sticks upon contact. In archival framing, acid-free and lignin-free formulations are preferred, ensuring that the tape does not discolor, off-gas, or deteriorate artwork. Some tapes are permanent, while others are repositionable or removable.

Materials Used

Backing materials: Paper, polyester film, Mylar, or polypropylene, providing structural integrity.
Adhesive: Acid-free, pH-neutral adhesives designed for long-term safety with paper, photographs, or other art materials.
Release liners: Protective paper or film that prevents premature adhesion before application.

Techniques

Ensure clean, dust-free surfaces before applying the tape to maximize adhesion and avoid trapping debris.
Apply firm, even pressure using a burnishing tool or fingers to secure the bond.
Use minimal tape near artwork edges to reduce the risk of long-term adhesive migration.
Choose repositionable or removable tape for temporary layouts, collages, or drafts.

Benefits

Adheres instantly without heat, moisture, or solvents.
Available in archival, acid-free versions suitable for conservation-grade framing.
Flexible application: can secure paper, mats, foam core, or lightweight panels.
Repositionable tapes allow adjustments without damaging the surface.
