Double Sided PE Foam Tape Jumbo Roll

Both Side Tape Company is the manufacturer of Double Sided PE Foam Tape Jumbo Roll for converters making mounting pads, foam spacers, gasket strips, and industrial bonding parts. This closed-cell PE foam tape is produced with 0.5 mm-3.0 mm foam thickness, 45-100 kg/m3 density, double-sided PSA coating, and selectable liners for slitting, kiss-cutting, rotary die-cutting, roller pressing, and controlled warm pressing.

Product Production

Product Overview

This double coated PE foam tape is designed around the behavior of closed-cell polyethylene foam, not just around roll size. The foam has enough softness to fill small assembly gaps, but it also keeps enough body to support cleaner slitting and more stable converted parts. In production trials, the important signs are practical: the edge should stay neat after slitting, the liner should peel smoothly after kiss-cutting, and the adhesive should not flow past the foam edge after warm pressing.

Thickness selection has a direct effect on how the part behaves in assembly. A 0.5-0.8 mm grade is often used for low-profile nameplates, overlays, badges, and thin mounting parts where the edge height must stay discreet. A 1.0-1.6 mm grade is a common working range for trim bonding, display frames, small appliance panels, and die-cut foam pads. A 2.0-3.0 mm grade gives more cushioning and gap compensation, but it should be checked carefully after pressing for edge lift, foam split, or over-compression.

Foam density is just as important as thickness. Softer 45-60 kg/m3 PE foam conforms more easily to curved trim, light texture, or slightly uneven plastic surfaces. Firmer 80-100 kg/m3 foam gives better edge support for spacers, gasket strips, and pre-cut mounting parts that must keep their shape after liner removal. For many 1.0-1.6 mm die-cut parts, 60-80 kg/m3 foam gives a useful balance between compression recovery, cutting cleanliness, and part handling.

Adhesive choice should match the surface and the working environment. Rubber adhesive gives fast initial tack and can help on some PE, PP, powder-coated, or textured surfaces. Acrylic and solvent acrylic adhesive grades are better suited to long-term holding, heat aging, humidity exposure, and cleaner die-cutting. Typical adhesive coating thickness is 50-120 um per side, and 180-degree peel adhesion is often checked in the 10-22 N/25 mm range after dwell, depending on the substrate and adhesive grade.

For roller lamination or warm pressing, this material should still be treated as a pressure-sensitive adhesive tape, not a heat-activated film. Moderate heat and pressure can improve adhesive wet-out, especially on slightly textured surfaces. Too much heat may soften the adhesive, create edge ooze, or compress the foam beyond the intended gap. A 24-72 h dwell check is recommended before mass production to confirm peel strength, edge lift, foam recovery, and visible adhesive overflow.

Benefits

• – Closed-cell PE foam supports cushioning, sealing, vibration damping, and gap filling with lower water absorption than open-cell foam.
• – 45-100 kg/m3 density options help match soft surface conformity with stronger die-cut edge support.
• – 0.5 mm-3.0 mm thickness options help control assembly height, compression pressure, and visible edge profile.
• – Rubber, acrylic, and solvent acrylic PSA systems support different tack, heat aging, humidity resistance, and substrate bonding needs.
• – Film, paper, or glassine liners can be selected for slitting, kiss-cutting, laminating, and matrix stripping.
• – Typical slitting tolerance of +/-0.5 mm to +/-0.8 mm helps maintain stable roll width after trial validation.

How should PE foam density and thickness be selected for die-cut mounting parts?

For die-cut PE foam tape, density and thickness should be selected together instead of separately. Low-density foam works well when the part needs to follow curved trim or slightly rough plastic, but it can show more edge compression during cutting. Higher-density foam is better for spacers, gasket strips, and mounting pads where shape retention matters after liner removal. For 1.0-1.6 mm parts, 60-80 kg/m3 foam is often a practical starting point. During validation, check compression recovery, edge cleanliness, matrix stripping, foam split, adhesive ooze, and bonding strength after 24-72 h.

– Die-cut foam pads for appliance panels, display frames, and plastic housings

– Automotive interior trim, emblem backing, decorative strips, and light mounting parts

– Nameplates, badges, signs, and membrane switch spacer bonding

– Electronic assembly gaskets needing cushioning, gap filling, and vibration damping

– Foam strips for painted metal, ABS, PVC, aluminum, sealed wood, and powder-coated surfaces

– Industrial converters producing slit rolls, mounting pads, foam spacers, and pre-cut adhesive parts

What should be checked before slitting, hot pressing, or die-cutting double sided PE foam tape?

Before slitting, check roll edge flatness, liner strength, foam thickness consistency, and adhesive balance on both sides. A weak liner may tear during narrow-width slitting, while too much adhesive flow can cause edge blocking. Before die-cutting, focus on kiss-cut depth, matrix stripping, liner release force, foam edge compression, and adhesive transfer to the tool. For warm pressing or roller pressing, use controlled pressure and moderate temperature to improve wet-out without softening the adhesive too much. Finished parts should be checked after 24-72 h for peel strength, edge lift, foam recovery, and visible adhesive overflow.

FAQ

Q1: Is this tape made with closed-cell PE foam?

Yes. It uses closed-cell PE foam for compression support, lower water absorption, and cleaner converting performance.

Q2: Which adhesive should be selected?

Rubber adhesive is useful for fast initial tack. Acrylic adhesive is better for long-term holding, heat aging, and cleaner die-cut parts.

Q3: Can it be used for die-cut foam parts?

Yes. It can be used for kiss-cut, rotary die-cut, flat-bed die-cut, pads, spacers, and gasket strips.

Q4: Is it suitable for hot pressing?

It can support controlled warm pressing or roller pressing, but it should be treated as PSA tape, not heat-activated tape.
