1 / 2OCA Tape
Optically Clear Adhesive tape for display lamination, touch panel bonding, and film-to-glass assembly — over 99% light transmission, UV-stable, and die-cuttable to narrow bond lines.
Light Transmission
>99% (corrected for reflection)
Construction
Carrier-free film adhesive — no central supporting layer
Optical Properties
Non-birefringent — does not distort or interfere with LCD/polarized screen function
Environmental Stability
Resists bubbling, yellowing, and delamination under heat, humidity, and UV exposure
Overview
ALS Tape supplies OCA (Optically Clear Adhesive) tape for display assembly, optical lamination, and precision bonding of transparent substrates. OCA is a carrier-free film adhesive — meaning it contains no central supporting layer — which allows superior light transmission, thinner bond profiles, and optical integrity that standard double-sided tape constructions cannot match. Transmission levels exceed 99% (corrected for reflection), the adhesive is non-birefringent once removed from the carrier film, and the bond maintains stability under high temperatures, high humidity, and UV exposure without bubbling, yellowing, or delamination. OCA is die-cuttable to narrow bond lines and minimizes material waste, making it suitable for both large-format display integration and compact consumer device assembly.
Category Focus
Double Sided Tape
Tissue, OCA, and flame retardant double sided tape constructions for lamination, bonding, and assembly.
Key Features
Over 99% Light Transmission — Carrier-free construction maximizes optical clarity without the absorption and haze introduced by standard double-sided tape backings.
Non-Birefringent — Does not distort light or interfere with LCD polarizer alignment, maintaining full display optical performance after lamination.
Environmental Durability — Resists bubbling, yellowing, and delamination under high temperature, high humidity, and UV light exposure for long-term display reliability.
Ultra-Thin Bond Profile — No carrier means thinner stack height and more design freedom in compact device assemblies where total thickness is tightly controlled.
Die-Cuttable to Narrow Lines — Easy to convert, supports minimal material waste, and works with narrow bond line geometries common in precision display and touch panel fabrication.
Broad Application Scale — From early smartphone and tablet assembly to large-scale automotive dashboards, cockpit avionics, and commercial projection and overlay surfaces.
Applications
LCD and touchscreen lamination in smartphones, tablets, and portable devices
Display film-to-glass and film-to-film optical bonding
Automotive dashboard display, GPS unit, and cockpit avionics lamination
