PVC Patch Glossary: A–Z of Custom PVC Patch Terms
A PVC patch glossary defines the materials, construction methods, backing types and ordering terms used in custom PVC patch production. This page lists every PVC patch term A–Z and links each one to the page that covers it in full. Terms are grouped by letter with jump navigation below, and numerals such as 2D, 3D and 3M sit at the end. The glossary is the terminology anchor for the whole site, so each value stated here matches every other page on custompvcpatches.co.uk.

How to Use This Glossary
Use the letter index to jump to a term, then follow the link inside any entry to reach the full page on that subject. Each definition states one fact in plain terms, and each entry points to the node that owns the topic in depth. Numerals appear in the final section.
Glossary
A
Adhesive backing (3M)
Adhesive backing is a peel-and-stick 3M film bonded to the reverse of a patch. The film fixes the patch to hard, smooth surfaces such as helmets, laptop shells and toolboxes, rather than fabric. Our 3M adhesive backing page explains where a peel-and-stick bond holds and where it does not. See also: Backing, Sew-on backing.
Airsoft patch
An airsoft patch is a morale or identification patch worn on plate carriers, rigs and loadouts during airsoft and milsim. Hook-and-loop backing dominates this use because players swap patches between kit. The airsoft and morale patches page covers subdued and glow variants for night play. See also: Morale patch, Hook-and-loop backing.
Artwork
Artwork is the logo, badge or crest supplied for reproduction as a moulded patch. Vector artwork produces the cleanest mould because it scales without loss of edge sharpness. Our artwork requirements page lists the file formats that reproduce well. See also: Vector file, Proof approval.
Glossary
B
Backing
Backing is the attachment layer applied to the reverse of a patch after curing. The backing choice does not affect the moulded face, because it is added once the rubber has already set. The backing hub compares velcro, sew-on, adhesive and plain options side by side. See also: Velcro backing, Sew-on backing, Adhesive backing.
BFPO delivery
BFPO delivery sends orders through the British Forces Post Office to serving personnel. We accept BFPO addresses on custom PVC patch orders. The BFPO delivery page sets out how forces addresses are handled. See also: Turnaround time.
Bleed
Bleed is the margin of artwork extended past the die line so no gap appears after cutting. Adequate bleed keeps colour running to the very edge of the finished patch. Our artwork requirements page specifies the bleed we need. See also: Die-cut, Vector file.
Glossary
C
Chenille patch
A chenille patch is a raised, yarn-loop textured patch with a vintage varsity aesthetic. Chenille uses looped yarn where PVC uses moulded rubber, so the two differ in texture and durability. Our PVC vs chenille comparison sets the two materials against each other. See also: Embroidered patch, Woven patch.
Colour matching
Colour matching reproduces a brand colour to a Pantone reference through the full depth of the PVC. The pigment is mixed into the liquid compound before moulding, so colour runs through the material rather than sitting on the surface. Our Pantone colour matching page explains full-depth pigment. See also: Pantone, Full-depth pigment.
Curing
Curing is the heat stage that sets poured liquid PVC into solid rubber. Curing fixes the relief permanently, so raised areas hold their shape for the life of the patch. Our guide on how PVC patches are made covers the full four-stage process. See also: Mould, Relief.
Custom die-cut shape
A custom die-cut shape follows the outline of your artwork instead of a stock profile. The mould is cut to your design regardless of shape, so a custom outline carries no extra tooling cost. Our die-cut shapes page explains shaped patches in detail. See also: Die-cut, Size.
Glossary
D
Die-cut
Die-cut describes an edge cut to the patch profile during moulding. The die-cut edge seals as the rubber sets, so it does not fray or unravel. Our die-cut shapes page shows how the outline is formed. See also: Custom die-cut shape, Edge finish.
Digital proof
A digital proof is the on-screen mock-up a customer approves before any tooling begins. Approval locks the design, because the next stage cuts that design into metal. Our proof approval page explains what to check on a proof. See also: Proof approval, Artwork.
Dual-layer patch (PVC and embroidery)
A dual-layer patch bonds a moulded PVC element onto an embroidered twill base. The PVC section carries fine detail and the embroidered section supplies thread texture on the same badge. Our PVC and embroidery combo page covers this hybrid build. See also: Twill, Embroidered patch.
Durometer
Durometer is the Shore-scale measure of PVC hardness. A lower durometer gives soft, flexible PVC, and a higher durometer gives rigid, hard PVC. Our guide on soft PVC vs hard PVC explains where each sits on the scale. See also: Soft PVC, Hard PVC.
Glossary
E
Edge finish
Edge finish is the border result of moulding, and on a PVC patch it is a clean die-cut seal. A PVC edge carries no stitched border, so nothing unravels over time. Our die-cut shapes page explains the sealed edge. See also: Die-cut, Merrow border.
Embroidered patch
An embroidered patch is a stitched-thread badge built on a twill base with a merrow border. Embroidery holds thread texture, while PVC holds moulded detail and resists water. Our PVC vs embroidered comparison weighs detail, weather resistance and heat tolerance. See also: Dual-layer patch, Twill.
Express production
Express production completes a run in 5 to 7 working days from proof approval. Express sits ahead of standard turnaround for orders on a tighter deadline. Our turnaround and delivery page lists both routes. See also: Standard production, Turnaround time.
Glossary
F
Full-depth pigment
Full-depth pigment is colour mixed into the liquid PVC before moulding, so it runs through the whole patch. Colour therefore does not fade, peel or crack the way surface printing does. Our Pantone colour matching page explains why full-depth pigment holds a brand colour. See also: Pigment, Colour matching.
Glossary
G
Glow-in-the-dark patch
A glow-in-the-dark patch contains phosphorescent pigment that charges under light and re-emits it in darkness. Charge time runs to roughly 15 minutes under direct light, followed by several hours of visible glow. Our glow-in-the-dark patches page covers night identification. See also: Reflective patch, Pigment.
Glossary
H
Hard PVC
Hard PVC is a higher-durometer blend used where rigidity matters more than flex. Hard PVC resists bending, while soft PVC returns to shape after flexing. Our guide on soft PVC vs hard PVC sets out the trade-off. See also: Soft PVC, Durometer.
Heat stabiliser
A heat stabiliser is a PVC additive that holds shape and colour under sunlight and high temperature. Stabilisers give the patch its UV resistance across long outdoor exposure. Our guide on what PVC patch material is lists every additive. See also: Plasticiser, UV resistance.
Hook-and-loop (velcro) backing
Hook-and-loop backing is a hook panel bonded to the reverse that fastens to a loop field on the garment. This backing makes the patch removable and repositionable, so wearers swap emblems between jackets, plate carriers and packs. Our velcro backing page covers tactical and swappable use. See also: Sew-on backing, Airsoft patch.
Glossary
I
Infrared (IR) compatible
IR compatible describes a subdued finish that behaves predictably under night-vision devices. Military and cadet units specify IR-compatible patches so kit stays low-signature after dark. Our military and cadets page covers subdued and IR requests. See also: Morale patch, Subdued colourway.
Iron-on (why PVC is not iron-on)
PVC patches are not supplied iron-on. Polyvinyl chloride softens above 120°C, and a domestic iron reaches 180°C on a cotton setting, which deforms the moulded relief. Our guide on why PVC patches cannot be ironed on explains the temperature limit and points to sew-on backing instead. See also: Sew-on backing, UV and heat resistance.
Glossary
L
Leather patch
A leather patch is an embossed or debossed badge made from genuine or faux leather. Leather reads as premium on denim and bags, while PVC reads as tough on outdoor gear. Our PVC vs leather comparison sets finish against durability. See also: Embroidered patch, Woven patch.
Glossary
M
Magnetic backing
Magnetic backing is a concealed magnet fixing that avoids piercing the garment. Magnets suit uniforms where a sew-on stitch line is unwanted. Our magnetic backing page explains where a magnet holds and where it does not. See also: Pin-and-clip backing, Plain backing.
Merrow border
A merrow border is an overlocked stitched edge, and it is the standard border on embroidered patches. PVC patches use a sealed die-cut edge instead of a merrow border, so no thread wraps the rim. Our PVC vs embroidered comparison shows the edge difference. See also: Edge finish, Die-cut.
Metallic-effect patch
A metallic-effect patch is finished to imitate a metallic surface without a metal component. The effect comes from pigment and surface treatment inside the PVC. This term links to the metallic-effect patches page, which is in preparation. See also: 3D PVC patch, Transparent patch.
Minimum order
There is no minimum order quantity for custom PVC patches. Unit price falls as quantity rises, because the mould cost spreads across the run. Our minimum order page explains how quantity affects price. See also: Pricing, Reorder.
Morale patch
A morale patch is a unit-identity or humorous patch, usually hook-and-loop backed for quick changes. Tactical, airsoft and security wearers use morale patches across changing roles. Our airsoft and morale patches page covers the format. See also: Airsoft patch, Velcro backing.
Mould
A mould is the engraved metal tool that shapes each patch. One mould serves the entire production run and every reorder of the same design. Our guide on PVC patch mould engraving explains how the tool is cut. See also: Mould engraving, Curing.
Mould engraving
Mould engraving cuts the approved design into the metal mould. Mould depth sets the relief: a shallow cavity produces a 2D patch, and a deep, multi-level cavity produces a 3D patch. Our guide on PVC patch mould engraving covers depth and detail. See also: Mould, Relief.
Glossary
N
Name patch
A name patch is a small PVC patch carrying a name or role, often velcro-backed for swapping. Name patches suit uniforms where the identifier changes between wearers or shifts. This term links to the name patches page, which is in preparation. See also: Hook-and-loop backing, Minimum text size.
Glossary
O
Oversized back patch
An oversized back patch is a large die-cut PVC patch for jacket and vest backs. PVC produces shapes up to 200mm without the fraying risk of a stitched border. This term links to the oversized back patches page, which is in preparation. See also: Motorcycle patch, Die-cut.
Glossary
P
Pantone (PMS)
Pantone, or the Pantone Matching System, is the colour reference used to lock a brand colour on every order. A PMS code fixes the exact colour, so reorders match the original run. Our Pantone colour matching page explains full-depth PMS matching. See also: Colour matching, Full-depth pigment.
Phthalates
Phthalates are plasticiser compounds, and some are restricted under REACH. We state phthalate and REACH compliance on the quality node. Our REACH and phthalates page sets out the position. See also: REACH, Plasticiser.
Pigment
Pigment is the colourant blended into liquid PVC before moulding. The pigment runs through the full depth of the patch, so colour does not sit on the surface. Our guide on what PVC patch material is covers pigment and additives. See also: Full-depth pigment, Pantone.
Pin-and-clip backing
Pin-and-clip backing is a butterfly-clutch pin fixing for lapels and caps. The pin pierces the fabric and the clutch holds it in place. Our pin-and-clip backing page explains the fixing. See also: Magnetic backing, Plain backing.
Plain backing
Plain backing is a patch supplied with no attachment layer. Manufacturers choose plain backing for heat-pressing, moulding-in, or loose supply to collectors. Our plain backing page explains when no backing is the right choice. See also: Backing, Adhesive backing.
Plasticiser
A plasticiser is a PVC additive that keeps the finished patch flexible instead of brittle. Plasticisers turn rigid PVC powder into the soft rubber a patch needs to bend with a garment. Our guide on what PVC patch material is lists every additive. See also: Heat stabiliser, Soft PVC.
Polyvinyl chloride (PVC)
Polyvinyl chloride is the thermoplastic polymer PVC patches are moulded from. Manufacturers plasticise the polymer into a soft, flexible rubber before moulding. Our guide on what PVC patch material is explains the material in full. See also: Plasticiser, Pigment.
Printed patch
A printed patch carries colour on the surface of a fabric or film base. Printing sits on top, while PVC pigment runs through the whole patch, so PVC resists fade and peel. Our PVC vs printed comparison sets the two methods against each other. See also: Full-depth pigment, Woven patch.
Proof approval
Proof approval is the customer sign-off on the digital proof. Turnaround starts at proof approval, not at enquiry, because mould engraving cannot begin on an unapproved design. Our proof approval page explains the sign-off stage. See also: Digital proof, Turnaround time.
PVC keyring
A PVC keyring is a moulded polyvinyl chloride keyring made with the same tooling process as a patch. Keyrings extend a brand set beyond patches. Our PVC keyrings page covers the product. See also: PVC zip pull, PVC label.
PVC label
A PVC label is a moulded brand label for garments and gear. Labels reproduce a logo in raised rubber like a patch. Our PVC labels page covers the product. See also: PVC keyring, Dual-layer patch.
PVC zip pull
A PVC zip pull is a moulded polyvinyl chloride pull that matches a patch or brand set. Zip pulls add a branded touch to jackets and bags. Our PVC zip pulls page covers the product. See also: PVC keyring, PVC label.
Glossary
R
REACH
REACH is the UK and EU chemical regulation that governs restricted substances such as certain phthalates in PVC. Compliance keeps a patch safe for wear and sale. Our REACH and phthalates page states the position. See also: Phthalates, Compliance.
Reflective patch
A reflective patch combines moulded rubber with a retroreflective panel that returns light towards its source. The panel activates under torchlight and headlights rather than glowing on its own. Our reflective patches page covers high-visibility use. See also: Glow-in-the-dark patch, Retroreflective.
Relief
Relief is the raised profile of a patch face. 2D relief is flat-topped, and 3D relief is sculpted and rounded across multiple heights. The patch types hub compares every construction type. See also: 2D PVC patch, 3D PVC patch.
Reorder
A reorder is a repeat run of a design already approved. A reorder costs less than the first run, because the mould already exists and needs no re-engraving. Our reorders and mould storage page explains how repeat orders work. See also: Mould, Minimum order.
Retroreflective
Retroreflective describes the optical property of returning light to its source. Reflective patches use a retroreflective panel to light up under a beam. Our reflective patches page explains the effect. See also: Reflective patch.
Glossary
S
Sample
A sample is a physical example produced to check finish before a full run. A sample confirms colour, relief and feel in the hand. Our samples page explains how samples are supplied. See also: Proof approval, Reorder.
Sew-on backing
Sew-on backing is a stitch channel or pre-punched holes around the border for a permanent bond. A sewn attachment survives industrial laundering and produces the strongest fixing of any backing type. Our sew-on backing page covers workwear and uniform use. See also: Hook-and-loop backing, Iron-on.
Shore hardness
Shore hardness is the durometer reading that classifies soft versus hard PVC. A low Shore reading means a flexible patch, and a high reading means a rigid one. Our guide on soft PVC vs hard PVC explains the scale. See also: Durometer, Soft PVC.
Silicone patch
A silicone patch is moulded from silicone rubber rather than polyvinyl chloride. Silicone and PVC look similar but differ in material, feel and cost. Our PVC vs silicone comparison sets the two rubbers apart. See also: Polyvinyl chloride.
Size
Size is the finished dimension of a patch, measured as the average of width and height. PVC patches are produced from 25mm to 200mm. Our sizes and shapes page explains the measurement convention. See also: Die-cut, Oversized back patch.
Soft PVC
Soft PVC is the standard low-durometer, plasticised polyvinyl chloride used for flexible patches. Soft PVC bends with the garment and returns to shape without cracking. Our guide on soft PVC vs hard PVC explains the difference. See also: Hard PVC, Plasticiser.
Standard production
Standard production completes a run in 10 to 14 working days from proof approval. Standard sits behind express for orders without a tight deadline. Our turnaround and delivery page lists both routes. See also: Express production, Proof approval.
Subdued colourway
A subdued colourway is a low-visibility, muted palette used on military and tactical patches. Subdued colours keep a patch low-signature in the field. Our military and cadets page covers subdued requests. See also: Infrared compatible, Morale patch.
Glossary
T
Thickness
Thickness is the finished depth of a patch. A 2D patch measures 2.5mm, and a 3D patch measures 3.5mm. Our guide on PVC patch thickness explained covers depth by construction type. See also: Relief, 2D PVC patch, 3D PVC patch.
Transparent patch
A transparent patch has clear PVC areas that show the surface beneath. The clear section reads as glass-like against a coloured design. This term links to the transparent patches page, which is in preparation. See also: Metallic-effect patch, Relief.
Turnaround time
Turnaround time is the production window measured from proof approval. Standard turnaround runs 10 to 14 working days, express runs 5 to 7 working days, and UK mainland delivery adds 1 to 2 working days. Our turnaround and delivery page sets out the full timeline. See also: Proof approval, BFPO delivery.
Twill
Twill is the woven base fabric used under the PVC layer in a dual-layer patch. Twill supplies the embroidered texture beneath the moulded section. Our PVC and embroidery combo page explains the hybrid build. See also: Dual-layer patch, Embroidered patch.
Glossary
U
UKCA and compliance
UKCA and compliance cover the UK conformity and material-safety signals for a patch. Compliance confirms a patch is safe for wear and sale in the UK. Our quality and compliance hub sets out the standards we work to. See also: REACH, Phthalates.
UV and heat resistance
UV resistance is the colour and shape stability of PVC under prolonged sunlight, aided by heat stabilisers. PVC holds its colour outdoors where printed transfers fade. Our guide on PVC patch UV and heat resistance explains the limits. See also: Heat stabiliser, Waterproof.
Glossary
V
VAT
VAT is UK value added tax, charged at 20%. PVC patch prices are quoted in pounds sterling excluding VAT. Our VAT and invoicing page explains pricing and invoices. See also: Minimum order, Reorder.
Vector file
A vector file is scalable artwork in a format such as AI, EPS, PDF or SVG. Vector artwork reproduces cleanly at any patch size because it holds sharp edges when scaled. Our artwork requirements page lists the formats we need. See also: Artwork, Bleed.
Velcro backing
Velcro backing is the common name for hook-and-loop backing. A hook panel on the patch fastens to a loop field on the garment, making the patch removable. Our velcro backing page covers swappable use. See also: Hook-and-loop backing, Morale patch.
Glossary
W
Washing and wash tolerance
Wash tolerance is the temperature a patch withstands in a machine wash. PVC patches tolerate a 40°C machine wash without fading or cracking. Our guide on washing PVC patches covers care for sewn and velcro patches. See also: Waterproof, UV and heat resistance.
Waterproof
Waterproof means the material absorbs no water. Solid PVC takes on no moisture, so rain and immersion leave a patch unchanged. Our guide on whether PVC patches are waterproof explains the property. See also: Wash tolerance, UV and heat resistance.
Woven patch
A woven patch is a fine woven-thread badge that holds small typography. Weaving reproduces fine detail flat, while PVC reproduces detail in raised relief. Our PVC vs woven comparison sets detail against durability. See also: Embroidered patch, Printed patch.
Glossary
# (Numerals)
2D PVC patch
A 2D PVC patch is built from flat layers on a single plane, so every raised surface finishes flat on top. A 2D patch measures 2.5mm thick and holds a 5mm minimum text height, which suits text, flat logos and line art. Our 2D PVC patches page covers the format. See also: Relief, 3D PVC patch.
3D PVC patch
A 3D PVC patch is poured against a sculpted mould that contours the surface into rounded relief. A 3D patch measures 3.5mm thick and holds a 6mm minimum text height, which suits faces, animals and detailed crests. Our 3D PVC patches page covers the format. See also: Relief, 2D PVC patch.
3M adhesive backing
3M adhesive backing is the peel-and-stick film described under adhesive backing. The 3M film bonds to hard, smooth surfaces rather than fabric. Our 3M adhesive backing page explains where it holds. See also: Adhesive backing, Plain backing.

Answers
Frequently Asked Questions
Is a PVC patch the same as a rubber patch?
Yes. A PVC patch and a rubber patch are the same product — a badge moulded from plasticised polyvinyl chloride. Suppliers use both names, along with silicone-style patch and morale patch, for the same soft PVC item.
Are PVC patches and silicone patches the same thing?
No. PVC patches are moulded from polyvinyl chloride, and silicone patches are moulded from silicone rubber. The two materials look similar but differ in feel, cost and chemistry, as our PVC vs silicone comparison explains.
Do PVC patches have a minimum order?
No. There is no minimum order quantity for custom PVC patches. Unit price falls as quantity rises, because the mould cost spreads across the run.
Can a PVC patch be ironed on?
No. Polyvinyl chloride softens above 120°C, and a domestic iron reaches 180°C, which deforms the relief. Sew-on backing gives a permanent bond on fabric instead, as our guide on why PVC patches cannot be ironed on sets out.
Does "2D" mean the patch is printed?
No. 2D describes flat-topped moulded relief, not printing. The design is still raised rubber with pigment through the full depth of the material.
Summary
In Short
This glossary gathers the working vocabulary of custom PVC patches into one A–Z reference. Each term names a material, a construction method, a backing type, a design attribute or an ordering rule, and each entry points to the page that treats the subject in depth. Read alongside the patch types hub and the ordering hub, the glossary turns a scattered set of trade terms into a single map of how a moulded rubber patch is specified, made and delivered in the UK.
