Double Coated PE Foam Tape

Double Coated PE Foam Tape is made with a closed-cell PE foam carrier, acrylic adhesive on both sides, and a controlled release liner for assembly fixing, die-cut mounting pads, and roll converting. As the manufacturer of this product, Double Seal Tape Company supplies it for metal, plastic, glass, trim, nameplate, and panel applications where balanced two-side adhesion, clean liner release, 180-degree peel consistency, and static shear performance need to remain stable after pressure and 24h dwell time.

Product Overview

Double Coated PE Foam Tape is not a thin double sided polyethylene tape with adhesive only for light temporary fixing. Its working value comes from the foam-supported double coated construction. The PE foam carrier gives the tape thickness, compression, and surface contact, while the acrylic adhesive on both sides helps two assembled parts bond with a more even contact area.

For thinner bond lines, 0.5 mm and 0.8 mm are often selected. When the assembly has a slight gap, a light curve, or a small surface mismatch, 1.0 mm, 1.5 mm, or 2.0 mm can give better foam contact. This helps metal nameplates, plastic trims, display frames, glass spacers, and die-cut mounting pads sit flatter after fixing, with less stress concentrated at the edge of the bonded part.

The release liner also deserves attention. In real converting work, it is not only a cover for the adhesive. It affects roll unwinding, slitting, kiss-cutting, matrix stripping, pad removal, and final placement. A stable liner helps the tape stay flat during narrow-width conversion and reduces adhesive transfer when small pads are lifted from the sheet. In typical production checks, open-side and liner-side 180-degree peel are compared after 20 minutes and again after 24 hours to confirm whether both adhesive layers remain balanced before bulk converting.

Benefits

• Balanced double coated construction: acrylic adhesive is applied on both sides of the PE foam carrier for stable bonding between two assembled surfaces.
• Useful thickness selection: 0.5 mm and 0.8 mm suit thin bond lines, while 1.0 mm, 1.5 mm, and 2.0 mm help compensate for small assembly gaps.
• Cleaner liner handling: controlled liner release helps remove die-cut pads without stretching the foam or pulling adhesive away from the carrier.
• Stable converting performance: the roll structure supports slitting, kiss-cutting, mounting squares, narrow strips, and cleaner matrix stripping.
• Two-side peel control: open-side and liner-side 180-degree peel can be checked after 24h dwell to compare adhesive consistency.
• Practical assembly reliability: bonding pressure, dwell time, surface cleaning, foam density, and liner release all influence the final mounting result.

How does release liner control affect die-cut mounting pads and roll converting?

Liner control becomes critical when the tape is converted into mounting pads, narrow strips, kiss-cut parts, or roll-format adhesive components. If release is too tight, small pads may deform during removal. If it is too light, the tape may lift during matrix stripping, sheet handling, or roll unwinding. For die-cut mounting pads, converters usually check pad flatness, liner curl, edge overflow, adhesive transfer, and clean peeling after 24-72h storage. A typical liner release range of 5-25 g/25 mm helps balance converting stability with easy pad removal when the liner is matched correctly.

Applications

• Die-cut mounting pads for trim, badge, and nameplate fixing
• Mounting squares and kiss-cut parts for appliance or electronic assembly
• Metal and painted panel bonding where screws are not preferred
• Plastic housing, ABS covers, PC panels, and PP parts after surface testing
• Glass spacer bonding for display, appliance, and decorative panel use
• Narrow-width roll converting for strips, pads, and converted adhesive components

What should be checked when bonding metal, plastic, and glass with double coated PE foam tape?

Before mass assembly on metal, plastic, or glass, the actual bonding surface should be tested instead of relying only on standard stainless steel data. Metal parts need oil-free cleaning, plastic parts may require surface energy checking, and glass should be free from dust, moisture, and release agent. Proper bonding pressure helps the acrylic adhesive wet the surface, while dwell time allows peel strength to build. Production teams should compare 180-degree peel on both sides, static shear under the expected load, foam compression after fixing, and edge lifting after 24-72h. If the liner-side adhesive leaves residue or peels unevenly, converting settings should be adjusted before bulk production.

FAQ

What is Double Coated PE Foam Tape used for?

It is used for assembly fixing, mounting pads, trims, nameplates, glass spacers, and converted roll parts.

Is the adhesive coated on both sides?

Yes. The PE foam carrier has acrylic adhesive on both sides, with a release liner protecting one adhesive face.

Can it bond plastic and glass?

Yes. ABS, PC, PP, painted surfaces, and glass should be tested with real pressure, dwell time, and load conditions.

Why is liner release important?

Liner release affects unwinding, die-cutting, matrix stripping, pad removal, and clean placement during final assembly.
