Double Sided EVA Foam Tape

Double Sided EVA Foam Tape is a double coated EVA foam bonding tape made with adhesive on both sides of a flexible EVA foam carrier. Double Sticky Tape Company is a manufacturer of this tape for mounting, bonding, roll converting, and die-cut adhesive parts. The release liner keeps the open adhesive surface clean before use, while the compressible foam core helps parts sit more closely on nameplates, signs, plastic housings, painted panels, and light metal components.

Product Overview

Double Sided EVA Foam Tape is made for parts that need adhesive contact on both sides, not a single sided foam backing. The EVA foam carrier sits between two pressure-sensitive adhesive layers, and the liner protects one adhesive face until the second part is ready to bond. This structure works well for nameplate backing, sign bonding, plastic and metal component mounting, decorative trim fixing, and pre-applied adhesive parts.

The EVA carrier gives the tape more body than thin film double sided tape. When pressure is applied, the foam compresses slightly, helping the adhesive touch more of the bonding surface. This is useful on lightly textured plastic housings, painted metal panels, acrylic signs, and nameplate backs that are not perfectly flat. Typical reference foam density can be selected around 45-90 kg/m3, depending on thickness stability, cushioning feel, and die cutting performance. For low-profile bonding, thinner grades are preferred. For visible mounting or a softer contact layer, 1mm-3mm is more commonly selected.

Adhesive grade should be chosen according to the surface and working condition. Acrylic adhesive is often used where aging resistance and stable long-term mounting are important. Rubber or hot melt adhesive can give faster initial tack for indoor bonding. On stainless steel or painted metal, typical 180 degree peel adhesion may reach 8-16 N/25mm after proper pressure and dwell time. On ABS, PVC, acrylic, coated panels, or low surface energy plastics, sample testing should be completed before bulk use.

Benefits

• Double sided adhesive coating bonds two parts without screws, liquid glue, or a separate backing adhesive.
• EVA foam carrier gives a soft contact layer for lightly uneven plastic, metal, acrylic, and painted surfaces.
• Release liner protects the second adhesive side during storage, slitting, die cutting, waste removal, and placement.
• Balanced peel adhesion and holding power support light-duty mounting when pressure, dwell time, and surface preparation are controlled.
• Conversion-friendly structure allows slit rolls, sheets, kiss-cut pads, and die-cut foam adhesive parts with typical slitting tolerance around +/-0.5mm.
• Custom converted formats can match manual application, semi-automatic assembly, nameplate backing, and sign bonding work.

How does the EVA foam carrier improve mounting and bonding performance?

The EVA foam carrier is more than a thickness layer. It works as a soft bonding core between two adhesive-coated surfaces. During application, firm pressure helps the foam compress and allows the adhesive to wet out more evenly on plastic housings, painted metal, acrylic signs, and nameplate backs. For more stable peel adhesion and holding power, the surface should be clean, dry, and free from oil or mold release residue. A typical dwell time of 24-72 hours is recommended before final load checks or edge-lifting evaluation.

Applications

• Nameplate bonding where the EVA foam layer helps the back side sit more evenly
• Sign bonding for acrylic signs, display strips, and lightweight panels
• Plastic and metal part mounting for light-duty industrial assembly
• Decorative trim and small component fixing on painted or coated surfaces
• Electronic accessory pads and pre-applied adhesive parts
• Kiss-cut foam tape pads supplied on release liner for easier peeling
• Slit roll converting for manual application or production-line assembly
• Die-cut adhesive parts used where clean edges, liner-assisted handling, and controlled tolerance are required

Where should release liner and die cutting be checked before production?

Release liner selection should be confirmed before mass production, especially when the tape will be slit, kiss-cut, or die-cut into adhesive parts. Liner stiffness, release force, and flatness can affect unwinding, cutting depth, waste stripping, adhesive transfer, and part positioning. For nameplate bonding, sign bonding, or plastic and metal component mounting, production-size samples should be checked for clean die-cut edges, smooth liner-assisted peeling, adhesive residue, edge lifting, and final bonding stability. For shaped parts, typical die-cut tolerance is usually controlled around +/-0.2mm to +/-0.5mm, depending on foam thickness and part geometry.

FAQ

1. Is Double Sided EVA Foam Tape coated with adhesive on both sides?

Yes. It uses an EVA foam carrier with pressure-sensitive adhesive on both sides, and the release liner protects the open adhesive surface before final bonding.

2. Can it be used for plastic and metal bonding?

Yes. It can bond many plastic and metal surfaces, but ABS, PVC, acrylic, painted metal, stainless steel, and low surface energy plastics should be tested before bulk production.

3. Can the tape be supplied as die-cut adhesive parts?

Yes. It can be converted into slit rolls, sheets, kiss-cut pads, and die-cut EVA foam adhesive parts for nameplates, signs, and component mounting.

4. What affects peel adhesion and holding power?

Adhesive type, EVA foam thickness, surface cleanliness, application pressure, 24-72h dwell time, temperature, and substrate surface energy all affect final performance.
