Double Coated PET Tape (Ultra-Thin & Black)

Double Coated PET Tape (Ultra-Thin & Black Options)

Charmetack Double Coated PET Tape is the industry standard for precision electronic assembly. Featuring a dimensionally stable PET carrier and modified acrylic adhesive, it offers high shear strength and ensures tight tolerances during high-speed die-cutting processes.

Ultra-Thin Profile — Available in thicknesses from 5µm to 30µm (Tesa 4972 equivalent) for ultra-slim devices.
Dimensional Stability — The non-stretchy polyester carrier prevents deformation, ensuring die-cut parts retain their exact shape.
Clear & Black Options — Available in Optically Clear (for lens bonding) and Black (for light blocking/shading).

product description

The Precision Standard for Electronic Assembly.

Charmetack’s Double Coated PET Tape (Polyester) combines a thin, high-strength PET carrier with a high-performance acrylic adhesive. It offers superior dimensional stability compared to tissue tapes, ensuring precise positioning for micro-components.

Engineered as a cost-effective alternative to Tesa 4972 / 4965, this tape is available in both Optically Clear (for screens) and Black (for light blocking) versions.

Why Electronics Engineers Choose PET Tape?

Dimensional Stability: The non-stretchy PET carrier ensures that die-cut parts maintain their exact size and shape during automated assembly.
Ultra-Thin Profile: Available in thickness down to 0.01mm (10µm) and 0.03mm (30µm) for ultra-slim devices where every micron counts.
High Shear Strength: Resists slippage and lifting, even under continuous load or elevated temperatures (+100°C).
Light Blocking (Black Version): Our Black PET tape effectively blocks LED light leakage around screens and bezels.

FAQ: PET Double Sided Tape

Q: What is the difference between Tissue Tape and PET Tape?

PET Tape is much stronger and does not tear or stretch. It is ideal for precision die-cutting where tight tolerances are needed. Tissue Tape is softer and better for rough surfaces.

Q: Can I use the Black PET for light blocking?

Yes. Our Black PET tape is specifically designed with black adhesive and black carrier to provide excellent optical opacity, preventing light leakage in electronic devices.
