Optically Clear Adhesive Films for Display Lamination

An Optically Clear Adhesive Film is an optically clear adhesive layer used to join transparent components. Documented OCA applications include laminating display layers and covers. The exact construction depends on the product: tesa® 88008 describes a pressure-sensitive acrylic adhesive layer without a carrier and with separate release liners. So check more than the term OCA. The substrates, optical stack and processing conditions of the specific film are essential to the choice.

Those names alone do not establish separate material classes. The related category pages use search terms for optically clear bonds; the actual choice follows each product's construction and documented properties. A product called a film can, for example, be a carrier-free adhesive layer with release liners. For purchasing decisions, the product identity, adhesive, thickness, liners and intended substrates are more useful than the page name.

Suitability depends on the particular Optically Clear Adhesive Film. The tesa® 880xx series is described for optical lamination behind covers made of glass, polycarbonate and PMMA. This does not establish suitability of every OCA product for those substrates. Tell us the materials of both parts, any coatings and the intended lamination process. The choice can then be checked against documented product information and your actual application.

We need the chosen film or the requirements of the bond, along with substrates, geometry, viewing area and desired delivery format. The sequence in which release liners are removed and components laminated is also relevant. Krückemeyer GmbH converts suitable materials into application-specific dimensions and shapes. Whether a custom cut or die-cut part is appropriate for the optical stack must be assessed against the material and application.
