High-Tack Blue Polyester Tape | High Opacity Light-Blocking PET Film
High-Tack Blue Polyester Tape | High Opacity Light-Blocking PET Film
High-Tack Blue Polyester Film Tape | High Opacity Light-Blocking Grade
Engineered with a premium blue-tinted polyester (PET) base film and a high-adhesion organic silicone pressure-sensitive adhesive. Combines exceptional light-shielding opacity, aggressive instant tack, and 180°C continuous heat resistance for display modules, battery packs, and industrial web splicing.
Precision Light Control & Heavy-Duty Industrial Adhesion
Standard clear or light-colored polyester tapes allow significant ambient light bleed, which compromises performance in optoelectronic display assemblies and sensor housings. Our High-Tack Blue Polyester Tape solves this by using a high-density blue original PET film carrier that delivers high optical opacity (>99% shading effect) across the visible spectrum.
Formulated with an ultra-aggressive silicone adhesive system, this tape bonds instantly to low-surface-energy (LSE) materials, metal chassis, and plastic housings. It withstands continuous operational temperatures up to 180°C and resists chemical exposure, acid, and moisture without lifting, flagging, or leaving sticky silicone residue upon removal.

Q: What makes "Original Blue PET" different from surface-dyed blue polyester tape?
A: Original blue PET uses masterbatch blue pigment incorporated during plastic resin extrusion. This ensures completely uniform color density and superior light-blocking opacity without dye leaching or fading under heat.
Q: Does the high-tack silicone adhesive bond well to low-surface-energy (LSE) materials?
A: Yes! Silicone adhesive natively offers outstanding adhesion to challenging substrates, including silicone-treated release liners, PTFE, fluoropolymers, and textured plastic housings.
Q: Will this tape leave adhesive residue when removed after high-temperature baking?
A: No. The silicone adhesive is thermally cross-linked to the blue PET backing, ensuring clean 100% residue-free removal even after exposure to 180°C heat cycles for extended periods.
Q: Can you supply precut die-cut shapes or specific narrow widths for display assembly?
A: Yes, we provide precision roll slitting down to 3mm widths as well as custom die-cut parts on release liners according to your CAD engineering drawings.
