3mm Thick Foam Double-sided Adhesive Tape in 15mm, 18mm & 30mm Widths for Mounting

This foam double-sided tape provides a practical solution for attaching objects where a thicker, gap-filling adhesive is needed. Unlike standard flat adhesive tapes, its 3mm thick foam core allows it to conform to slightly uneven surfaces and create a cushioned bond. Available in three specific widths – 15mm, 18mm, and 30mm – it offers flexibility for different project scales, from picture hanging and craft assembly to mounting lightweight fixtures. Its strong adhesive ensures a reliable hold on clean indoor surfaces.

Features and Construction

The tape is defined by its specific construction and available size options, which dictate its practical uses.

Material and Build

The tape uses BOPP (biaxially-oriented polypropylene) as its base material. This plastic film provides a stable and strong backing for the adhesive layers. The key functional component is the 3mm thick foam layer, which is coated with strong adhesive on both sides. This spongy middle layer is what allows the tape to absorb minor surface imperfections and provide a degree of cushioning between the mounted objects, offering an advantage over thinner, rigid tapes.

Size and Practical Fit

The product is offered in three distinct size variants to suit different project requirements. One option is 15mm wide with a total length of 2 metres. The other two options are wider: an 18mm width and a 30mm width, each supplied on a 3-metre long roll. The choice of width allows users to match the tape's coverage area to the size of the items being bonded, with wider tapes providing more surface area for a stronger overall hold on larger objects.

Uses and Placement

Its thick, strong adhesive profile makes this tape suitable for a variety of indoor bonding tasks where a permanent or semi-permanent fix is required.

Event or Professional Use

In professional or event settings, this tape can be used for mounting lightweight signage, securing temporary displays on walls or boards, or assembling promotional stands and props. The 3mm foam allows it to stick effectively to textured surfaces like brick-effect wallpaper or slightly rough boards where flat tape might fail. The wider 30mm variant is particularly suited for these heavier-duty display applications where a broader bond is beneficial.

Everyday Home Use

For home and hobby use, it is ideal for craft projects, framing pictures without using clips, mounting hooks or small shelves on walls, and assembling DIY projects. The 15mm and 18mm widths are well-suited for these smaller-scale tasks, such as securing mirrors, attaching cork boards, or bonding foam sheets and model parts in craft work. It provides a clean, screw-free mounting solution.

Benefits and Buying Value

The value of this tape lies in its specific functional design, offering an adhesive solution that addresses the limitations of standard tapes.

Reuse and Low Maintenance

While designed as a strong, permanent adhesive, the product requires minimal maintenance once applied. For users who need to reposition items during application, the tape allows a brief window for adjustment if pressed lightly initially. Once the final firm press is applied, it sets into a reliable bond. Its key maintenance advantage is its simplicity—no tools, mixing, or drying time are required.

Why Choose This Product

Choose this foam double-sided tape when you need more than a flat adhesive. The 3mm thickness is its primary differentiator, solving the problem of bonding uneven or slightly mismatched surfaces. The choice of three widths provides flexibility, and the BOPP backing contributes to the tape's overall strength and handling. It is a specialised stationery and mounting product designed for situations where a thicker, cushioning adhesive bond is the specific requirement.
