- Color: black, white, gray, or custom
- Carrier: PE foam, PU foam, EPDM, neoprene, or rubber
- Adhesive: acrylic PSA, rubber PSA, or differential PSA
- Liner: paper, PET, glassine, coated paper, or dual liner

Both Side Tape Company is a manufacturer of Double Sided Gasket Tape for gasket lamination, two-face bonding, die-cut assembly, and positioning work. The tape is made with a foam or rubber carrier coated with pressure-sensitive adhesive on both sides, while liners protect the adhesive faces before lamination and final placement. Typical structures range from 0.2 mm-5.0 mm total thickness and are used for kiss-cut gasket parts, clean matrix stripping, and stable bonding to metal, plastic, foam, and rubber surfaces.

Product Overview
Double Sided Gasket Tape is designed for assemblies where a gasket needs adhesive contact on both faces. It is not a single-sided sealing strip and should not be selected only by initial tack. In a typical gasket lamination process, one adhesive side is laminated to foam, rubber, plastic film, or a pre-cut gasket substrate. The opposite liner stays in place until the part is ready for final assembly.
This staged process keeps the second adhesive face clean and flat during slitting, die cutting, storage, and handling. It also reduces the risk of dust, fingerprints, edge stretching, and adhesive contamination before the gasket is placed into a metal housing, plastic cover, foam pad, or rubber cushion.
For gasket conversion, the important balance is carrier thickness, adhesive coat weight, liner release, and die-cut stability. A 1.0 mm foam carrier with 60-80 um adhesive on each side may be useful for light compression and gap filling, while a thinner rubber carrier can help where a lower profile and firmer positioning are required. Before mass production, samples should be checked after 24h and 72h dwell for peel strength, liner removal force, edge ooze, adhesive stringing, and part alignment after compression.
Benefits
- Provides controlled adhesive contact on both gasket faces during staged assembly.
- Helps foam or rubber gaskets stay aligned during lamination and final positioning.
- Dual-liner options protect adhesive surfaces until each bonding step is ready.
- Smooth adhesive coating helps reduce local high spots, edge ooze, stringing, and bonding gaps.
- Supports kiss-cut parts, part-on-liner supply, and cleaner matrix stripping.
- Helps limit shifting on metal housings, plastic covers, foam pads, and rubber cushions.
- Differential adhesive options can be used when two bonding surfaces have different surface energy.
- 24-72h sample observation helps confirm peel strength, liner release, edge stability, and part alignment before volume production.
How do liners, kiss cutting, and matrix stripping affect double sided gasket tape assembly?
In die-cut gasket production, the liner does more than cover the adhesive. It affects feeding, lay-flatness, cutting depth, waste removal, and final part release. During kiss cutting, the blade should cut through the adhesive and carrier while keeping the bottom liner unbroken, so the finished gasket stays in position on the sheet or roll. If release is too loose, small holes, narrow ribs, or thin gasket walls may lift during matrix stripping. If release is too tight, the part may stretch during peeling. For complex gasket profiles, stable liner release helps keep the adhesive edge clean and the part shape accurate before assembly.

What makes double sided gasket tape suitable for gasket lamination and two-face bonding?
A double coated gasket tape is useful when one side needs to laminate to the gasket material first, while the opposite adhesive face remains protected for later bonding. This allows the gasket to be die cut, stripped, stored, and handled before the final liner is removed during assembly. On metal, plastic, foam, and rubber surfaces, the adhesive should wet out evenly without excessive edge flow. Sample checks should include peel after 24h and 72h, part alignment after compression, liner removal force, edge ooze, adhesive transfer, and whether the adhesive edge stays clean after matrix stripping.
FAQ
Q1: Is Double Sided Gasket Tape the same as a single-sided sealing strip?
No. Double Sided Gasket Tape has adhesive on both faces and is used for gasket lamination and two-face assembly bonding.
Q2: Can it be supplied as kiss-cut gasket parts?
Yes. It can be supplied as sheets, rolls, or kiss-cut parts on liner for easier positioning and cleaner matrix stripping.
Q3: What surfaces can it bond to?
Typical surfaces include metal, plastic, foam, rubber, coated panels, and selected gasket substrates after surface testing.
Q4: What should be tested before production?
Check liner release, die-cut edge quality, matrix stripping, peel adhesion, edge ooze, adhesive stringing, and 24-72h dwell stability.
