Two Face Tape Company is a manufacturer of Double Sided Polyester Tape for printed nameplates, membrane switches, electronic components, and industrial mounting parts. This double coated polyester tape uses a stable polyester film carrier to support both adhesive layers during slitting, lamination, die cutting, and final assembly. It is made for thin bonding designs that require clean edges, accurate alignment, controlled peel adhesion, and better shape retention during production handling.

Product Overview
This polyester film carrier tape is developed for industrial converting work where unsupported adhesive may stretch, curl, or lose its shape. The polyester carrier gives the tape a controlled internal structure, so converted parts can stay flatter during narrow-width slitting, small-hole punching, kiss cutting, and roll-to-part lamination.
The carrier is thin, but it provides useful tensile support. Typical carrier tensile strength is around 120-180 MPa, with elongation around 80%-130%. In practical use, this helps reduce distorted windows, shifted holes, uneven borders, and edge wave after cutting. For printed panels, overlays, spacer layers, and electronic mounting parts, that stability is often just as important as peel strength.
The adhesive system can be selected according to the bonding surface. Acrylic adhesive is commonly used where aging resistance, heat exposure, and stable bonding are required on stainless steel, PC, ABS, PET overlay film, painted metal, and smooth industrial substrates. Rubber adhesive can be considered when faster initial tack is more important. For production approval, the tape should be tested on the real material, not only on standard stainless steel panels. Ink-coated nameplates, hard-coated overlays, printed PET films, ABS housings, and painted metal surfaces can show different wet-out, edge lifting, and peel adhesion after 24-72h dwell time. Narrow borders, small windows, and repeated pressing areas should also be checked for adhesive ooze, liner shift, and alignment after roller pressure.
Benefits
- Stable carrier structure: The polyester film carrier helps reduce stretching, curling, and shape change during slitting, die cutting, and lamination.
- Cleaner converted edges: Narrow borders, small holes, and display windows can be cut with less adhesive ooze, edge deformation, and liner shift.
- Useful tensile support: Typical carrier tensile strength around 120-180 MPa helps printed overlays, nameplates, and thin mounting parts keep better handling strength.
- Better dimensional control: Dimensional change is typically <=0.5% after 70 C x 2h heat aging, helping holes, windows, and switch areas remain aligned.
- Substrate-specific bonding: Peel adhesion can be checked on stainless steel, PC, ABS, PET overlay film, painted metal, and printed ink layers before production use.
- Smoother part handling: Controlled liner release force, typically 10-35 g/25 mm depending on liner, supports cleaner transfer and automatic placement.
What should be checked before using Double Sided Polyester Tape for printed nameplates and membrane switches?
For printed nameplates and membrane switches, peel strength alone is not enough. The adhesive must wet out on the ink layer without lifting, staining, whitening, or swelling at the edge. A die-cut polyester adhesive tape should also keep small holes, windows, spacer areas, and narrow borders in position after converting. During sample approval, production teams should check 24-72h dwell adhesion, edge lifting, adhesive squeeze-out, liner shift, and alignment after roller pressure. For membrane switch parts, repeated pressing areas should also be checked for shear stability and shape retention, because small movement may affect switch response and overlay appearance.
Applications
- Printed metal and plastic nameplates requiring clean edges and stable overlay alignment
- Graphic overlay bonding for badges, labels, and decorative panels
- Membrane switch spacer layers where hole position and window cuts must remain accurate
- Electronic component fixing and insulating spacer attachment on flat substrates
- Thin film, foil, and plastic part lamination with controlled thickness
- Industrial panel, badge, and trim mounting on stainless steel, PC, ABS, PET, and painted surfaces

How does the polyester film carrier improve dimensional stability in industrial mounting parts?
The polyester film carrier works as a controlled support layer inside the adhesive construction. When the tape is slit into narrow rolls or converted into small die-cut parts, the carrier helps reduce stretching, twisting, and shape distortion. This is important in nameplates, membrane switches, and electronic assemblies because hole position, edge line, window alignment, and spacer location must remain accurate after cutting and lamination. A stable carrier also helps the adhesive part release from the liner without curling, tearing, or losing its intended shape before bonding.
FAQ
Is this tape suitable for ordinary office use?
No. It is made for industrial bonding, converting, and assembly applications.
Can it be die cut into small parts?
Yes. The polyester film carrier supports clean die cutting, small-hole punching, and narrow-edge parts.
What surfaces should be tested before production?
Stainless steel, PC, ABS, PET overlay film, painted metal, and printed ink layers should be tested.
How long should sample bonding be observed?
A 24-72h dwell test is recommended to check peel adhesion, edge lifting, adhesive ooze, liner shift, and adhesive stability.
