Ordinary pressure-sensitive tape is one of the worst static generators on a production floor. Unwinding a roll of standard cellophane or PVC tape can produce charges of several kilovolts — far above the damage threshold of modern semiconductors, some of which are sensitive below 100 V. ESD-safe tapes solve this in two ways: they present a controlled surface resistance so charge can bleed away instead of accumulating, and they use low-charging film and adhesive chemistry so unwinding and peeling generate minimal triboelectric charge in the first place.
Industry practice, following ANSI/ESD and IEC 61340 conventions, divides materials into three working bands. Conductive materials measure below roughly 1×10^4 Ω/sq and drain charge quickly. Static dissipative materials fall between about 1×10^4 and 1×10^11 Ω/sq and bleed charge slowly enough to avoid damaging current spikes. Insulative materials, above ~1×10^11 Ω/sq, hold charge and have no place in static-controlled work. Most ESD tapes and anti-static tapes are specified in the dissipative band, which is the safest general-purpose choice for handling sensitive electronics.
An ESD Protected Area (EPA) operated under ANSI/ESD S20.20 or IEC 61340-5-1 requires that process-essential materials inside the zone be either dissipative, grounded conductive, or demonstrably low-charging. Tape qualifies as a process-essential insulator unless you specify an ESD-safe grade, so every roll used for sealing shielding bags, bundling cables, securing work instructions, or masking boards inside the EPA should carry a documented resistance grade.
A practical rule of thumb: use dissipative, low-charging tape for everyday sealing and fixing tasks near sensitive devices, and reserve conductive grades for cases where the tape must participate in a grounding path or sit adjacent to shielding structures such as copper foil or EMI shielding tapes. For incoming inspection, a surface resistance meter check plus the supplier's datasheet — including ASTM D3330 peel adhesion values and RoHS/REACH declarations — is usually sufficient for audit traceability.
Two printed formats dominate EPA housekeeping. The first is the familiar yellow-and-black ESD warning tape, printed with the ESD susceptibility symbol and "ATTENTION — STATIC SENSITIVE" style text. It is used to seal static shielding bags and transport boxes so that any opened package is immediately visible, and to mark EPA boundaries, racks, and floor zones. The carrier itself should still be low-charging — a printed warning on an insulative film defeats the purpose.
The second is printed grid tape: a transparent dissipative tape overprinted with a fine grid pattern. The grid serves as an instant visual cue that the tape is the ESD-safe variant, preventing mix-ups with ordinary clear office tape on the bench. Grid tape is the standard choice for resealing moisture barrier and shielding bags after sampling, because it identifies the closure as ESD-compliant without obscuring bag labels.
Cellulose (cellophane-type) carriers are the traditional choice for clear ESD grid tape. They tear by hand, accept print well, and naturally charge less than many plastic films, which makes them convenient for bag sealing and bench work. Their limitation is temperature and tensile strength — keep them to room-temperature tasks.
PET carriers offer higher tensile strength, better moisture resistance, and service temperatures of roughly 120–220°C depending on grade, making them suitable for fixing, splicing, and light-duty masking in warmer processes. Polyimide carriers extend the range to approximately 260–300°C, which is why anti-static polyimide tape with silicone adhesive is the default for masking gold fingers and components during reflow and wave soldering — the silicone system removes cleanly after heat exposure. For background on temperature classes, see our guides on Kapton tape temperature ratings and choosing high-temperature tape; for adhesive chemistry trade-offs, see acrylic vs rubber adhesives.
First, fix the resistance grade your EPA program requires — dissipative for general use, conductive only where grounding demands it. Second, confirm low charge generation on unwind and removal, not just surface resistance; both specifications should appear on the datasheet. Third, choose the carrier by process temperature: cellulose for ambient bench work, PET up to its rated range, polyimide for soldering operations. Fourth, match the adhesive to removal needs — silicone for clean high-temperature release, acrylic where UV and aging resistance matter over longer dwell times.
Fifth, check documentation and format: ASTM D3330 peel values stated as typical ranges, RoHS and REACH compliance certificates, and availability in the widths, lengths, or die-cut shapes your line consumes. Pre-cut pieces from a die-cutting service reduce operator handling, which itself lowers tribocharging events at the workstation.
HONGFU manufactures factory-direct ESD tapes and anti-static tapes across cellulose, PET, and polyimide carriers, including printed grid and warning formats, alongside related high-temperature and shielding products.

| Grade | Typical Surface Resistance | Behavior | Common Use |
|---|---|---|---|
| Conductive | Below ~1×10^4 Ω/sq | Drains charge rapidly; can be grounded | Grounding points, shielding layers, EMI-adjacent applications |
| Static dissipative | ~1×10^4 to ~1×10^11 Ω/sq | Bleeds charge in a slow, controlled way | General EPA sealing, bench fixing, bag closure |
| Anti-static / low-charging | Often dissipative range; key spec is low tribocharging | Generates minimal charge on unwind and removal | Sealing shielding bags, masking near sensitive components |
| Insulative (standard tape) | Above ~1×10^11 Ω/sq | Holds charge; can generate high voltages on unwind | Not suitable inside an EPA |
Most EPA applications call for a static dissipative tape, typically in the ~10^4 to ~10^11 Ω/sq range, combined with low charge generation on unwind. Conductive grades (below ~10^4 Ω/sq) are reserved for applications where rapid charge drainage or grounding is required. Always confirm the grade against your facility's ANSI/ESD S20.20 or IEC 61340-5-1 program requirements.
The terms overlap but are not identical. "ESD tape" usually refers to the measured surface resistance grade (conductive or dissipative), while "anti-static" or "low-charging" describes how little triboelectric charge the tape generates when unwound or peeled. A good EPA tape should satisfy both: a dissipative surface and low charging behavior. Ask suppliers for both specifications rather than assuming one implies the other.
No. Standard cellophane, PVC, and packing tapes are insulative and can generate several kilovolts of static when unwound — enough to damage Class 0 and Class 1 components. Inside an EPA, replace them with low-charging dissipative tapes for sealing, bundling, and marking, and verify incoming lots with a surface resistance meter if your audit program requires it.
Use a polyimide-carrier anti-static tape with silicone adhesive. Polyimide film withstands roughly 260–300°C, covering reflow and wave-solder profiles, and silicone adhesive removes cleanly after heat exposure. PET carriers (~120–220°C depending on grade) suit lower-temperature processes, while cellulose grades are best kept to room-temperature bench and packaging tasks.
Residue depends on the adhesive system, not the ESD grade. Silicone adhesives are preferred for high-temperature clean removal; acrylic adhesives offer good UV and aging resistance for longer-term applications. Peel adhesion is typically reported per ASTM D3330, and reputable manufacturers also provide RoHS and REACH compliance documentation with each lot.
