What is double-sided tissue tape used for?
Double-sided tissue tapes are thin, flexible adhesive tapes with adhesive on both sides, used for bonding, mounting and laminating. The carrier in the middle is tissue paper, which makes the tape easy to tear by hand and gives better flexibility and conformability on curved surfaces than a film carrier does.
LKJ® Tissue Tape is built that way at a total thickness of 60 microns, with high-tack hot-melt adhesive on both faces. Because the carrier is so thin, the bond line effectively disappears: two surfaces sit together as if laminated, which is why the tape is specified for posters, stationery, invitation boxes and paper wristbands, and for signage, photo mounting, foam mounting and point-of-sale displays.
Tissue is the thinnest carrier in the LKJ® specialty tapes range, and the carrier choice is usually the first decision a buyer has to make.
Where a job calls for a thicker tissue tape, a solvent-based adhesive or a printed liner, the group makes seven PTK® grades for exactly that. The full PTK® grade range on Prateek® Tapes runs from 70 to 100 microns plus the premium 910, 1200 and 1600 grades, so you can step up when the substrate is harder to hold.
Why does tissue tape have a release liner?
A double-sided tape has adhesive on both faces, so one of them has to be protected until the tape is in position. That is the release liner. On LKJ® Tissue Tape it also does a second job: it gives a clean look with no print bleed-through, which matters when the tape is applied to a printed sheet and the finished face has to stay unmarked.
In practice the liner is what makes the tape usable at speed. The operator lays the tape down, positions the part, then peels the liner and closes the joint, no wet adhesive, no drying time, no squeeze-out at the edges. The adhesive has high initial tack, so it bonds on contact rather than needing a cure.
The same liner behaviour is why the tape slits cleanly from 4mm to 1020mm with no adhesive drag or fibre tear on the cutter, which keeps narrow-width production consistent.
Is tissue tape strong enough for mounting work?
For the applications it is made for, yes. The adhesive is a high-tack hot-melt system coated on both sides, and the tape is used for photo mounting, foam mounting, signage and lightweight component fixing as well as for paper work. It bonds on contact, which means the joint is holding as soon as the parts are pressed together.
What tissue tape does not do is fill a gap. The carrier is 60 microns, so both surfaces have to meet. If one of them is uneven, textured or curved enough to leave an air gap, a compressible foam carrier is the right choice instead, LKJ® Foam Tape uses a 2mm EVA foam for that reason.
For heavier or more demanding bonds on metal, glass, coated paper and low surface energy plastics such as PP and PE, look at PTK® 910 premium double-sided tissue tape, which is formulated for nameplates, membrane switches and chrome labels.
