PET Double Sided Tape

Double Bond Tape Company is a manufacturer of PET Double Sided Tape for industrial bonding, laminating, mounting, and die-cut assembly. This double coated PET tape uses a stable PET film carrier with acrylic adhesive on both sides, giving production teams a clean bonding layer with controlled thickness, liner release, and slitting performance. Clear film, red film, and yellow paper liner options are available for electronics, appliance panels, nameplates, display frames, plastic parts, and other industrial assembly work.

Product Overview

PET Double Sided Tape is used when an assembly needs a thin adhesive layer that stays stable during converting and final bonding. The PET film carrier gives the tape better dimensional control than unsupported adhesive film, especially during slitting, lamination, kiss cutting, and small-part placement. When the material is converted into 5 mm narrow rolls or die-cut adhesive pieces, the carrier helps reduce stretching, curling, and part distortion. PET carrier construction is useful when dimensional stability and a controlled thin bond line are required. For low-profile router templates or CNC positioning, PET-carrier tape may be worth evaluating where limited bond-line thickness is important, but adhesion and removal should still be tested on the actual wood surface. See the router template and CNC tape selection guide for the complete comparison. Peel, shear, dwell and surface-removal checks should be confirmed for the selected adhesive grade before routine use.

The standard construction is release liner, acrylic adhesive, PET carrier, acrylic adhesive, and release liner. For general mounting work, 100 um and 125 um total thickness are often selected because they balance thin profile and holding strength. Thin grades such as 50 um and 80 um fit narrow gaps, membrane switches, display parts, and thin panel bonding. Heavier grades such as 150 um and 205 um provide more adhesive mass for nameplates, appliance badges, ABS trim, and slightly uneven contact surfaces.

Liner choice should match the converting process. Red film liner is easy to identify during die cutting, waste matrix stripping, and manual positioning. Yellow glassine paper liner is practical for regular slit rolls and standard converting. Clear film or PET liner is useful when cleaner cutting, lower paper dust, or more stable release is needed for automatic placement.

Benefits

The reinforced polyester film core helps keep slit rolls flatter during rewinding, laminating, and rotary die cutting.
Double coated structure gives balanced bonding on both sides for film, foam, plastic, metal, glass, and coated panels.
Acrylic adhesive PET tape supports stable 180-degree peel adhesion after 24h dwell on properly cleaned surfaces.
Clear, red film, yellow paper, and PET liner options help match positioning, waste removal, and automatic feeding.
Slit roll widths from 5 mm to 1240 mm support both narrow mounting strips and wide lamination rolls.
Standard slitting tolerance is typically +/-0.5 mm, with tighter control available for narrow roll projects.

How should thickness and liner be selected for PET double sided tape?

Thickness should be selected according to the bonding gap, surface texture, and holding requirement. A 50 um or 80 um double sided polyester tape is suitable when the part has limited space and the bonding surface is flat. A 100 um or 125 um grade is a common choice for balanced industrial mounting. For nameplates, ABS trim, appliance panels, and parts with slight surface unevenness, 150 um or 205 um can improve contact area and long-term holding.

The liner should be chosen according to the way the tape will be handled. Red film liner is easier to see during die cutting, waste matrix stripping, and positioning. Yellow paper liner works well for regular slit rolls and standard converting. PET liner is preferred when cleaner edges, lower paper dust, and stable release are important. For narrow rolls below 10 mm, liner release and edge ooze should be checked after 24-72h storage before large-scale use.

What should be checked before die-cutting or laminating PET double sided tape?

Before die cutting, the liner release, adhesive thickness, and roll tension should be checked together. If the release is too tight, small die-cut parts may lift during waste removal. If it is too loose, parts may shift during rewinding or automatic feeding. For narrow strips, slitting burrs, edge ooze, and adhesive transfer should be inspected after 24-72h storage, especially when the width is below 10 mm.

Before laminating, the bonding surface should be dry, clean, and free from oil, dust, silicone, and mold-release residue. ABS, PC, PET, metal, glass, and painted panels usually bond well after cleaning. PP, PE, EPDM, powder-coated surfaces, and very low surface energy plastics may need primer, corona treatment, or separate bonding tests. For painted panels and coated plastics, cleaning method and dwell time often affect final peel strength more than initial tack. For a broader process covering foam surface assessment, lamination, liner behavior, die cutting and pilot validation, use the foam converting adhesive tape guide.

FAQ

Q1: What is PET Double Sided Tape used for?

It is used for industrial mounting, laminating, die-cut parts, nameplates, electronics, display frames, appliance panels, and plastic component bonding.

Q2: Can this tape be supplied in narrow widths?

Yes. It can be slit into narrow rolls from 5 mm, with typical width tolerance around +/-0.5 mm depending on roll width and material structure.

Q3: Which liner is better, red film or yellow paper?

Red film is useful for visual positioning and die cutting. Yellow paper is practical for general roll converting and standard assembly.

Q4: Should samples be tested before production?

Yes. A 24-72h dwell test, peel adhesion check, static shear test, edge lifting inspection, and surface compatibility check are recommended before production.
