Double-sided tissue tape uses a thin non-woven (tissue) carrier coated on both sides with pressure-sensitive adhesive — most commonly a solvent or water-based acrylic, sometimes a rubber-based system for higher initial tack. The tissue layer is there to stabilize the adhesive and make the tape easy to handle, slit and tear by hand; it contributes little mechanical strength of its own.
Typical total thickness runs around 0.08–0.16 mm, and continuous temperature resistance is usually in the 60–80 °C range, limited by the adhesive rather than the carrier. Its defining traits are conformability and economy: the soft carrier follows curved, textured or slightly irregular surfaces, and the low material cost makes it a default choice for high-volume mounting, splicing, lamination, nameplate fixing and general assembly work.
Double-sided PET tape replaces the tissue with a polyester film carrier, typically coated on both sides with acrylic adhesive. PET film is dimensionally stable, tear-resistant and thin — total tape constructions commonly fall between roughly 0.05 mm and 0.20 mm — which allows a strong bond line in tight assemblies such as electronics, displays and membrane switches.
The PET film itself tolerates roughly 120–220 °C depending on grade, although in practice the adhesive sets the working limit: acrylic-coated PET tapes typically serve around 100–150 °C continuously. Because the film does not stretch or fuzz, PET tape die-cuts cleanly into small, precise shapes and survives automated placement and rework far better than a paper-like carrier. For even higher temperatures, see how to choose a high-temperature tape.
The carrier is the real difference between these two products, and it drives almost every performance gap. Tissue is soft, compressible and hand-tearable, so it conforms to curves and rough substrates but stretches and distorts under load. PET film is stiff in the plane of the tape, holds its dimensions under tension and heat, and resists tearing during application — but it bridges rather than fills surface texture, so it performs best on flat, smooth, clean substrates.
Temperature behavior follows the same logic. Both tapes are usually adhesive-limited, but the PET carrier gives the laminate more headroom: a tissue tape softens and loses cohesion well before a comparable PET construction. Neither, however, is a true high-heat product — for soldering, powder coating or PCB masking above ~150 °C you should look at polyimide (Kapton-type) tape instead, whose film withstands roughly 260–300 °C.
Adhesive chemistry is specified separately from the carrier. Acrylic adhesives offer better UV, plasticizer and aging resistance; rubber adhesives grab faster and bond better at low temperatures but age and yellow sooner. The trade-offs are covered in detail in acrylic vs rubber adhesive tape.
Tissue tape earns its place wherever speed, conformability and cost dominate the specification. Typical applications include mounting lightweight signage, POS displays and decorative trim; splicing paper, films and foils in converting lines; laminating foam, leather and textiles; and general-purpose bonding in stationery, packaging and craft products. Hand-tearability matters on assembly lines where operators apply tape without dispensers or knives, and the soft carrier helps the adhesive wet out on slightly rough or curved surfaces.
Its limits are equally clear: avoid tissue tape where the joint sees sustained heat above ~80 °C, continuous shear load, outdoor UV exposure (unless an acrylic adhesive grade is confirmed), or where the part must be die-cut to tight tolerances. If you need a thicker, gap-filling bond on irregular surfaces, an EVA, PE or acrylic foam tape is often the better step up than simply stacking tissue tape.
Specify PET double-sided tape when the bond line must stay thin, strong and dimensionally exact. Common use cases include bonding components inside electronics and appliances, fixing FPCs, lenses and graphic overlays, membrane switch assembly, and any part produced by precision die-cutting — the film carrier cuts to clean edges and keeps its shape through kiss-cutting, lamination and automated placement.
PET is also the safer choice when the assembly passes through moderately hot processes such as drying ovens or reflow-adjacent zones below the adhesive's limit, or when the tape may need to be lifted and repositioned during rework without tearing. If your application removes the carrier from the equation entirely — pure adhesive lamination of foams, foils or graphics — a carrier-free transfer tape is worth comparing as a third option.
Whichever carrier you choose, compare suppliers on the same basis: peel adhesion per ASTM D3330 with stated dwell time, total thickness and tolerance, temperature rating (continuous vs short-term), liner type for your converting process, and RoHS/REACH compliance documentation. Always validate with samples on your actual substrate, since published steel-panel values do not guarantee performance on low-surface-energy plastics or powder-coated metal.
HONGFU manufactures both double-sided tissue tape and double-sided PET tape factory-direct in China, alongside the broader double-sided adhesive tape range and in-house die-cutting services for converted parts. For datasheets, samples or volume pricing on either construction, send an inquiry with your substrate, temperature and thickness requirements.

PET double-sided tape is generally the better die-cutting substrate. Its film carrier holds tight dimensional tolerances, resists stretching on rotary and flatbed presses, and produces clean edges on small or intricate shapes. Tissue tape can be die-cut for simpler, larger geometries, but the soft non-woven carrier is more prone to edge fuzz and distortion.
Most tissue tapes are rated for roughly 60–80 °C in continuous service, with short-term peaks somewhat higher depending on the adhesive. The limit comes from the adhesive system rather than the carrier. If your assembly sees sustained heat above this range, move to a PET-carrier tape or a polyimide-based product.
Tissue tape is usually the lower-cost option per square meter because the non-woven carrier is inexpensive and the tape runs at high coating speeds. PET tape costs more due to the film carrier, but the premium is often justified where strength, heat resistance or die-cutting precision would otherwise cause rejects or rework.
Yes. Both tissue and PET carriers are commonly coated with solvent acrylic, water-based acrylic or rubber-based adhesives. Acrylic offers better UV and aging resistance; rubber gives higher initial tack, especially at lower temperatures. The carrier and the adhesive should be specified separately against your substrate, temperature and durability requirements.
Ask suppliers for peel adhesion measured to ASTM D3330 (typically 180° peel on stainless steel) so values are directly comparable, and confirm the dwell time used. Also request RoHS and REACH compliance documentation, and validate with samples on your actual substrate — published values on steel do not always predict performance on plastics or powder coatings.
