Optical Adhesive Film

An Optical Adhesive Film (commonly known as OCA film) is a highly transparent, dry, double-sided pressure-sensitive adhesive engineered to bond touch panels, cover lenses, and display modules (like LCD or AMOLED screens) without liquid curing.

Key Features

• High Transparency: Offers high light transmittance (typically >98% to 90%+) and low haze (<1%) to eliminate internal air gaps and boost outdoor contrast.
• Clean Dry Bonding: Eliminates messy liquid handling, flow control, and long thermal or UV curing cycles.
• Durability: Provides reliable adhesion, anti-shatter/explosion-proof support, and resistance to environmental factors like heat and moisture.
• Versatile Uses: Widely utilized in smartphone screens, touch displays, automotive gear, and specialized laboratory plates (such as qPCR sealing films).
