# Tape

Tape's backing material and adhesive chemistry, not its brand, decide whether it holds permanently, releases cleanly, insulates electrically, or bonds two surfaces without screws. Which of six product types it is (washi, masking, packing, duct/gaffer, double-sided, electrical) sets which spec-sheet rows matter next.

## How it works

Tape is a backing film or fabric coated on one or both faces with a pressure-sensitive adhesive that bonds on contact, no heat or solvent needed. The backing sets mechanical behavior: crepe paper tears by hand and lifts cleanly for masking; woven cloth or scrim adds tear-resistance for duct and gaffer tape; stretchy PVC vinyl conforms around wire splices for electrical insulation; thick acrylic foam (VHB) replaces screws by spreading load over a bonded area; thin oriented polypropylene (BOPP) film seals cartons cheaply. The adhesive sets removability and heat tolerance: natural rubber holds hardest but ages into residue, acrylic balances hold and clean release, silicone survives the most heat, and hot-melt bonds instantly but softens under heat. A safety-rated tape (UL 510 for electrical, ASTM for packaging/masking) has been tested against that failure mode specifically.

1. **Tape type.** Washi, masking, packing, duct/gaffer, double-sided, or electrical tape?
   Each type has its own spec sheet: a washi tape's paper weight has nothing to do with an electrical tape's voltage rating. This fork decides which facet set applies.
   If washi_decorative: ask Paper weight/feel; skip Electrical tape thermal class, Voltage rating, Scrim reinforcement, Surface finish, Foam or film core, Tape thickness (mounting tape), Minimum application temperature, Service temperature class, Packing tape thickness grade, Clean-removal window.
   If masking_painters: ask Clean-removal window, Outdoor/UV rated; skip Electrical tape thermal class, Voltage rating, Scrim reinforcement, Surface finish, Foam or film core, Tape thickness (mounting tape), Minimum application temperature, Service temperature class, Paper weight/feel, Packing tape thickness grade.
   If packing_shipping: ask Packing tape thickness grade; skip Electrical tape thermal class, Voltage rating, Scrim reinforcement, Surface finish, Foam or film core, Tape thickness (mounting tape), Minimum application temperature, Service temperature class, Paper weight/feel, Clean-removal window.
   If duct_cloth_gaffer: ask Scrim reinforcement, Surface finish; skip Electrical tape thermal class, Voltage rating, Foam or film core, Tape thickness (mounting tape), Minimum application temperature, Service temperature class, Paper weight/feel, Packing tape thickness grade, Clean-removal window.
   If double_sided_mounting: ask Foam or film core, Tape thickness (mounting tape), Minimum application temperature, Service temperature class; skip Electrical tape thermal class, Voltage rating, Scrim reinforcement, Surface finish, Paper weight/feel, Packing tape thickness grade, Clean-removal window.
   If electrical_insulating: ask Electrical tape thermal class, Voltage rating; skip Scrim reinforcement, Surface finish, Foam or film core, Tape thickness (mounting tape), Minimum application temperature, Service temperature class, Paper weight/feel, Packing tape thickness grade, Clean-removal window.
   Skip if already known: a query that already names the tape type, an earlier answer naming the job (wiring, boxes, painting, mounting).

2. **Clean release or permanent.** Need it to peel off clean later, or is permanent fine?
   Clean release needs synthetic rubber or acrylic adhesive on a tearable backing; permanent hold tolerates natural rubber, which ages into residue. This decides which adhesive_type to favor.
   If permanent_hold_fine: skip Clean-removal window.
   Skip if already known: an earlier answer naming masking, painting, or staging (implies clean release), an earlier answer naming repair, sealing, or bundling for good (implies permanent).

## What to surface

### Tape type

Which of the six common tape families this is: washi/decorative, masking/painter's, packing/shipping, duct/cloth/gaffer, double-sided/mounting, or electrical/insulating. Each family is judged on a different spec sheet. Asking this first avoids asking about voltage rating on a washi tape or paper weight on an electrical tape. [4] [1]

Values: washi_decorative, masking_painters, packing_shipping, duct_cloth_gaffer, double_sided_mounting, electrical_insulating.
Question to ask: Washi, masking, packing, duct/gaffer, double-sided, or electrical tape?

Used as: top-level split, filter. Data: derived from listing fields, backfill cost low. Look for it as: Derive from product title/category keywords (washi, painter's/masking, packing/shipping/carton, duct/gaffer, double-sided/mounting/VHB, electrical/insulating).
Title keyword match covers nearly every listing; ambiguous titles default to packing_shipping, the most common generic tape.

### Clean release or permanent

Whether the tape is designed to peel off cleanly without residue (often time-limited) or to hold for good and may leave residue or tear on removal. This is the single biggest adhesive trade-off in the category: synthetic rubber and acrylic release clean, natural rubber holds harder but ages into residue. [5] [11]

Values: needs_clean_release, permanent_hold_fine, unspecified.
Question to ask: Need it to peel off clean later, or is permanent fine?

Used as: top-level split, filter. Data: needs research, backfill cost low. Look for it as: Infer from category name: painter's/masking/gaffer tape implies clean release; duct/packing/electrical tape implies permanent is acceptable.
Category-name keyword match; low confidence for generic 'cloth tape' listings that could be either.

### Outdoor/UV rated

Whether the tape is formulated to survive sunlight and outdoor exposure without the adhesive breaking down or the backing degrading. A tape without UV stabilizers chalks, hardens, or releases early outdoors; brands that rate a tape for exterior use test it against this specifically. [11] [12]

Values: rated_for_outdoor_uv, indoor_only_or_unspecified.
Question to ask: Will this sit outdoors in sunlight, or stay inside?

Used as: filter. Data: needs research, backfill cost medium. Look for it as: Look for 'UV resistant', 'exterior', or 'outdoor' in the description; absence usually means indoor-only.
Not every listing states this explicitly; brand spec sheets are more reliable than retail bullets.

### Foam or film core

Whether a double-sided tape's core is a thick acrylic foam (VHB-style, for structural mounting) or a thin film/paper core (for light bonding or crafts). Foam core gap-fills and spreads stress over an area, which is what lets it replace screws or rivets; a thin film core is for light, flat-to-flat bonding only. [6]

Values: acrylic_foam_vhb_style, thin_film_or_paper_core, unspecified.
Question to ask: Mounting something heavy, or just bonding light, flat pieces?

Used as: filter, shown on the card. Data: on the listing, backfill cost low. Look for it as: 'VHB', 'foam mounting tape', or 'heavy duty double-sided' in the title signals foam core; 'double-sided tape' alone usually means thin film.
Keyword match; default plain 'double-sided tape' listings to thin_film_or_paper_core.

### Adhesive chemistry

What the sticky layer itself is made of: acrylic, natural rubber, synthetic rubber, hot-melt, or silicone. Chemistry decides heat tolerance and aging: natural rubber holds hardest but hardens/yellows into residue over time, acrylic balances hold and clean release, silicone survives the most heat, hot-melt bonds instantly but softens when warm. [9] [1]

Values: acrylic, natural_rubber, synthetic_rubber, hot_melt, silicone, unspecified.

Used as: filter, shown on the card. Data: on the listing, backfill cost low. Look for it as: Often named in the title or bullets ('acrylic adhesive', 'rubber adhesive', 'hot melt').
Keyword match; default to acrylic when unstated since it is the most common general-purpose chemistry.
Chart: position on a hold-strength vs clean-release axis.

### Backing material

What the tape's carrier layer is made of: crepe or flat paper, woven cloth/scrim, PVC vinyl, BOPP film, acrylic foam, or metal foil. Backing decides tear behavior and conformability: paper tears by hand for masking, cloth/scrim resists tearing for duct work, vinyl stretches around splices, foam carries load for mounting. [4] [11]

Values: crepe_paper, flat_paper, woven_cloth_scrim, pvc_vinyl, bopp_film, acrylic_foam, aluminum_foil, unspecified.

Used as: filter, shown on the card. Data: on the listing, backfill cost low. Look for it as: Usually in the title ('duct tape', 'foam mounting tape', 'vinyl electrical tape', 'crepe masking tape').
Title keyword match; cross-checks cleanly against tape_type since each family favors one backing.

### Safety/performance standard

Whether the tape carries a recognized test standard or listing for its job: UL 510 for electrical insulating tape, or an ASTM D10.14 packaging/masking specification for paper or cloth tape. A listed tape has been independently tested against a specific failure mode (dielectric breakdown, flame spread, water resistance); an unlisted tape of the same type has not, even if it looks identical. [1] [2] [4] [3] [15]

Values: ul_510_electrical_listed, astm_paper_masking_packaging, astm_cloth_packaging, none_common_for_type.

Used as: filter, shown on the card. Data: needs research, backfill cost medium. Look for it as: UL 510 is usually printed on electrical-tape packaging; ASTM numbers are rarely on retail listings and must come from the brand spec sheet.
Default duct/packing/washi tape to none_common_for_type unless the listing states a standard; default electrical tape to ul_510_electrical_listed unless stated otherwise, since it is the de facto baseline.

### Packing tape thickness grade

The BOPP film's caliper, which maps to a marketed grade: roughly 1.6-1.8 mil economy, 2.0-2.6 mil industrial/standard, up to 3.2 mil heavy duty. Thicker film resists puncture and holds heavier cartons closed longer; thinner film is cheaper per roll and fine for light boxes. [8] [9]

Range: 1.6 to 3.2 mil.

Used as: filter, shown on the card. Data: on the listing, backfill cost low. Look for it as: Thickness in mil is commonly in the title or bullets for packing tape ('1.8 Mil', '2.6 Mil Industrial').
Parse the mil number directly from title/bullets; default to the 1.6-1.8 mil economy band when absent.
Chart: position on a strength/thickness axis.

### Clean-removal window

How long the tape can stay applied (commonly up to 14 days for painter's tape) and still peel off without residue or lifting paint. A painter who leaves masking tape up longer than its clean-removal window risks residue or pulled paint; this is the number brands race to extend. [11] [12]

Values: up_to_14_days, unspecified_or_shorter.
Question to ask: Will this stay masked for more than about two weeks?

Used as: filter. Data: on the listing, backfill cost low. Look for it as: Painter's tape listings usually advertise the day count directly ('14-Day Clean Release').
Keyword/number match on 'day' claims; default to unspecified_or_shorter for plain masking tape with no stated window.

### Surface finish

Whether the tape's outer surface is glossy/polyethylene-coated or matte/low-reflective. Matte finish is the reason film and stage crews reach for gaffer tape over duct tape: it will not throw glare under lights or reflect on camera. [5]

Values: matte_low_reflective, glossy_poly_coated, unspecified.
Question to ask: Does it need to avoid glare or shine on camera?

Used as: filter, shown on the card. Data: on the listing, backfill cost low. Look for it as: Gaffer tape listings usually say 'matte'; plain duct tape listings usually don't mention finish at all.
Keyword match on 'matte'/'gaffer'; default duct-tape listings to glossy_poly_coated.

### Electrical tape thermal class

The adhesive's heat-tolerance class on an electrical tape: B (rubber), F (acrylic), or H (silicone). Rubber-class tape is cheapest and tackiest for everyday splices; acrylic resists heat-aging near motors; silicone is chosen only when the job runs hottest, since it costs the most. [1]

Values: class_b_rubber, class_f_acrylic, class_h_silicone, unspecified.

Used as: filter, shown on the card. Data: needs research, backfill cost high. Look for it as: Rarely on the retail listing; stated on the brand's technical data sheet as 'thermal class' or by adhesive chemistry.
Default to class_b_rubber, the everyday baseline, when the listing names no thermal class and the adhesive is unstated.
Chart: position on a heat-tolerance axis, B lowest to H highest.

### Voltage rating

Whether the tape is rated for general-purpose insulation at the common 600V class, or needs layering/a self-fusing tape for higher-voltage splices. Most PVC electrical tape on the shelf is rated to the same ~600V class; a single wrap of it is not a substitute for self-fusing tape or extra layers on a higher-voltage splice. [1] [2]

Values: general_purpose_600v, requires_layering_or_self_fusing, unspecified.

Used as: filter. Data: on the listing, backfill cost low. Look for it as: Often printed on packaging as 'rated to 600V' or similar; absence usually still means the 600V baseline.
Default general-purpose PVC electrical tape to general_purpose_600v unless the listing states a higher-voltage/self-fusing design.

### Scrim reinforcement

Whether a duct/cloth tape's backing is reinforced with a woven scrim (cotton, polyester, rayon, or fiberglass mesh) laminated under the film, or is film-only. Scrim is what keeps duct tape from stretching and tearing under load; a film-only 'duct-style' tape without scrim is noticeably weaker. [4]

Values: cloth_or_cotton_scrim, fiberglass_mesh, film_only_no_scrim, unspecified.

Used as: filter, shown on the card. Data: needs research, backfill cost medium. Look for it as: Rarely stated outright; 'cloth tape' or 'reinforced' in the title suggests scrim is present.
Default duct/gaffer-type listings to cloth_or_cotton_scrim, the common construction, unless stated otherwise.

### Minimum application temperature

The lowest surface/air temperature at which a double-sided foam tape can be applied and still bond properly. Pressure-sensitive adhesive gets too firm to wet out a surface below its minimum application temperature, so a cold-weather install needs a tape rated for it. [6] [7]

Range: 0 to 15 °C.
Question to ask: Applying this somewhere cold, or at room temperature?

Used as: shown on the card. Data: needs research, backfill cost high. Look for it as: Stated on the brand's technical data sheet, not on retail listings; varies by product family within a line.
Default to the room-temperature baseline (around 21°C ideal) when the family's minimum isn't known.

### Service temperature class

How much sustained heat a double-sided foam tape's bond can take: a general-purpose class good to roughly 90°C long-term, or a high-heat class whose short-term ceiling varies by family, from about 121°C for most VHB families up to 150°C for specific thicker-bond families like 3M VHB 4951. A bond used near an engine, light fixture, or sun-facing exterior panel needs the high-heat class; the general-purpose class will soften and creep under sustained heat it wasn't rated for. [6] [7]

Values: general_purpose_up_to_90c_long_term, high_heat_121_to_150c_short_term, unspecified.
Question to ask: Will it sit somewhere hot, like an engine?

Used as: filter, shown on the card. Data: needs research, backfill cost high. Look for it as: Stated on the brand's technical data sheet by product family; rarely on the retail listing.
Default foam mounting tape to general_purpose_up_to_90c_long_term unless the family is marketed as high-temperature; even then, confirm the specific family's short-term figure since it ranges 121-150°C.
Chart: position on a heat-tolerance axis.

### Maximum service temperature

The highest ongoing ambient temperature the applied tape's bond is rated to withstand before the adhesive softens or creeps. A tape sealing a box or wrapping ductwork near heat (a sun-baked truck bed, a warm vent) needs its service-temperature ceiling checked, not just its film thickness. [9] [10]

Range: 82 to 93 °C.

Used as: shown on the card. Data: on the listing, backfill cost low. Look for it as: Sometimes present in a product page's structured spec data as 'Service Temperature Max'; otherwise only on the brand's data sheet.
Default packing/duct tape to the general BOPP/cloth baseline (roughly 80-95°C) when the listing states no figure.
Chart: position on a heat-tolerance axis.

### Adhesive tack (steel peel)

How hard the tape grips on first contact, measured as 90° peel-adhesion force to stainless steel in oz per inch of width. Higher peel-adhesion means the tape grabs and holds immediately on a smooth surface; a low number can mean a seam that lifts under light stress. [9] [10]

Range: 19 to 60 oz/in.

Used as: shown on the card. Data: on the listing, backfill cost low. Look for it as: Sometimes present in a product page's structured spec data as 'Adhesion to Stainless Steel'; otherwise only on the brand's data sheet.
Not comparable across tape types built for different jobs (packing vs. duct); leave unspecified rather than guess when absent.
Chart: position on a tack-strength axis.

### Elongation at break

How far the tape's backing stretches before it tears, as a percent of its original length. Higher elongation lets a tape conform around corners and absorb shock before tearing; lower elongation resists stretching under load but splits sooner once overstressed. [9] [10]

Range: 20 to 150 %.

Used as: shown on the card. Data: on the listing, backfill cost low. Look for it as: Sometimes present in a product page's structured spec data as 'Elongation'; otherwise only on the brand's data sheet.
Default to the packing/duct baseline range when the listing states no figure.
Chart: position on a stretch-before-tear axis.

### Tape thickness (mounting tape)

How thick the double-sided foam tape itself is, before liner. A thicker foam gap-fills uneven or textured surfaces and absorbs more vibration; a thinner tape bonds smooth, flat surfaces with less visible tape line. [6] [7]

Range: 0.4 to 2.3 mm.

Used as: shown on the card. Data: needs research, backfill cost high. Look for it as: Stated in the brand's technical data sheet by product family (e.g. '0.045 in / 1.1 mm', up to '0.090 in / 2.3 mm' for the thickest families); rarely on the retail listing.
Match the named product family to its data sheet thickness when the family name is in the title.
Chart: position on a gap-filling/thickness axis.

### Paper weight/feel

How light and translucent the washi tape's paper backing is, from sheer tissue to a heavier, more opaque sheet. A sheerer, lighter paper shows the surface underneath and tears cleanly by hand for layering in journals and scrapbooks; a heavier paper feels sturdier and hides what's beneath it. [13] [14]

Values: thin_translucent, medium_body, heavier_opaque, unspecified.

Used as: shown on the card. Data: needs research, backfill cost high. Look for it as: Essentially never stated on a retail listing; inferred from product photos or brand descriptions of the paper.
Default washi tape to medium_body, the common weight, absent any stated paper weight.

## Numbers worth computing

| Metric | Formula | Why |
|---|---|---|
| Tensile strength per mil | `tensile_strength_N_per_10mm / film_thickness_mil` | How much break strength a packing tape's film delivers per unit of thickness; a higher number means the film is doing more work per mil rather than relying on sheer bulk. [9] |

## What you give up

- Duct tape's natural-rubber adhesive holds harder and ages into a sticky residue; gaffer and painter's tape trade some of that raw hold for an adhesive designed to lift away clean, even after it's been up a while. [5] [11] Board branch: "More permanent hold, less clean removal".
- A thinner BOPP film costs less per roll and seals light boxes fine, but it punctures and splits more easily under a heavy or overstuffed carton than the thicker industrial and heavy-duty grades. [8] [9] Board branch: "Thinner and cheaper, less puncture resistance".

## Words you will meet

- **Scrim**. A thin woven fabric mesh laminated inside duct or cloth tape's backing to stop it from stretching and tearing.
- **Dielectric strength**. How much electrical voltage a material can block before it breaks down and conducts; what electrical tape is rated by.
- **VHB (Very High Bond)**. 3M's name for a thick acrylic-foam double-sided tape strong enough to replace screws or rivets in some mounting jobs.
- **Mil**. One thousandth of an inch; the usual unit for how thick a tape's film or backing is.
- **BOPP**. Biaxially oriented polypropylene, the clear, strong plastic film most packing tape is made from.
- **UL 510**. The Underwriters Laboratories safety standard that electrical insulating tape is tested against for dielectric strength and flame retardancy.
- **ASTM**. ASTM International, the standards body behind the paper- and cloth-tape specifications (like D6123 for masking/light packaging) that set what a tape must survive.
- **Washi**. Traditional Japanese paper made from plant fibers like paper mulberry, gampi, or mitsumata; the backing washi tape is made from.
- **Gaffer tape**. A matte, cloth-backed tape built for film and stage crews to apply and then remove cleanly without glare or residue.
- **Pressure-sensitive adhesive (PSA)**. An adhesive that bonds on contact with light pressure, with no heat, water, or solvent needed to activate it.
- **Hot-melt adhesive**. An adhesive applied molten that sets as it cools; bonds fast but softens again if it gets warm.
- **Crepe paper**. A crinkled, easily hand-torn paper used as the backing on most masking and painter's tape.
- **Thermal class**. A letter grade (B, F, H) for how much heat an electrical tape's adhesive can take before it fails.
- **Clean release**. Adhesive designed to lift off a surface without leaving residue or pulling up paint or finish underneath.
- **Self-fusing tape**. A silicone-rubber tape with no sticky adhesive that bonds to itself under tension, used to build insulation thickness for higher-voltage splices.

## Where we made a call

- General-purpose PVC electrical tape is rated to the same ~600V class; higher-voltage splices need layering or self-fusing tape, not a thicker single wrap. (confidence medium). Corroborated by two brand/specialist spec pages (nibal, tapespec); neither is an independent lab or regulator, so treat the 600V figure as industry-typical, not universal. [1] [2]
