Double Sided PET Polyester Acrylic Adhesive Tape

Both Side Tape Company is a manufacturer of Double Sided PET Polyester Acrylic Adhesive Tape for thin industrial bonding that needs stable thickness, clean cutting edges, and dependable acrylic adhesion. The tape uses a PET/polyester film carrier with acrylic adhesive coated on both sides, protected by release paper or film. It is made for nameplate bonding, panel assembly, graphic overlays, membrane switches, display windows, and electronic parts where foam tape or general craft tape is not the right fit.

Product Overview

This double coated polyester tape is designed for flat, thin, and controlled bonding work. The polyester film core helps the tape stay stable during slitting, laminating, and die cutting, so narrow strips, small tabs, and adhesive frames are easier to handle during assembly. On stable shapes, typical die-cut tolerance can reach +/-0.2 mm, depending on the cutting tool, part size, and liner choice. This is not a gap-filling foam material. It is used when the final part needs a thin adhesive layer, a clean edge profile, and accurate placement.

The acrylic adhesive is coated evenly on both sides of the PET/polyester carrier, giving the tape a balanced structure for joining two flat surfaces. In typical reference testing, adhesion to stainless steel is usually in the range of 8 – 18 N/25 mm after proper pressure and dwell time. The final result can change with adhesive coat weight, total thickness, surface energy, and cleanliness. For aluminum nameplates, PC windows, PET overlays, ABS panels, painted housings, and printed ink layers, testing on the real production surface is recommended. Oil residue, ink curing, coating texture, and release-agent contamination may all affect wet-out or edge lifting.

 

 

Benefits

• Stable polyester carrier: Helps reduce stretching, curling, and shape change during roll slitting, sheet laminating, and die-cut converting.
• Uniform acrylic coating: Supports steady bonding from edge to edge across the roll width, especially for small converted parts.
• Thin bonding profile: Keeps nameplates, overlays, and electronic layers flat without adding bulky foam thickness.
• Useful shear holding: Static shear can reach >=24 h under standard lab conditions when applied with firm pressure on a clean surface.
• Cleaner die-cut parts: PET film improves pickup stability for small frames, narrow strips, tabs, and parts with inner holes.
• Controlled liner release: Typical release force can be 10 – 40 g/25 mm, depending on liner type and adhesive construction.
• Practical aging resistance: Acrylic adhesive gives useful resistance to indoor heat, humidity, UV exposure, and long-term industrial use when matched with the right surface.

What should be checked before selecting a PET polyester acrylic adhesive tape for panel and nameplate bonding?

Before mass production, the tape should be checked on the actual panel surface, not only on clean stainless steel. Powder coating, brushed aluminum, PC, PET, ABS, painted panels, and printed ink layers can each change adhesive wet-out. For nameplates and control panels, check whether the tape wets the surface fully after firm pressure, whether the edge stays flat after 24 hours, and whether peel strength improves after 72 hours. For heat or humidity exposure, a simple edge-lifting check after 70 C for 2 hours or 60 C/90% RH for 24 hours can help reveal bonding risks before bulk assembly.

How does liner selection affect die-cutting, laminating, and electronic assembly?

The liner does more than protect the adhesive during storage. A glassine or PE-coated paper liner works well for many slit-roll and manual assembly jobs, while PET film liner gives smoother release and better flatness for small die-cut parts. For membrane switch layers, display windows, and narrow adhesive frames, the release liner should remove smoothly without tearing, curling, or pulling adhesive from the PET carrier. During trial cutting, check waste stripping, adhesive ooze, edge cleanliness, and pickup stability of die-cut adhesive parts. For automatic placement, liner release force should stay consistent across the roll so each adhesive part transfers cleanly.

FAQ

1. Is this tape suitable for foam mounting applications?

No. It is a thin PET/polyester film carrier tape for flat bonding, not a foam tape for gap filling or cushioning.

2. Can it be supplied as die-cut parts?

Yes. It can be converted into slit rolls, sheets, kiss-cut parts, frames, tabs, strips, and drawing-based shapes.

3. Which surfaces should be tested before production?

Stainless steel, aluminum, PC, PET, ABS, painted panels, powder-coated parts, and printed ink layers should be tested with real assembly pressure.

4. How long should adhesion be checked after bonding?

Initial tack can be checked quickly, but final bonding performance is better evaluated after 24 – 72 hours of dwell time.
