The materials,
defined.

What is BOPP?

The no-label-look film. Clear, waterproof, food-contact safe, used on premium bottle wraps and cosmetic packaging across most of the DTC trade you respect.

Biaxially-Oriented Polypropylene

What is PET?

The strong-arm of the label trade. Heat-resistant, chemically inert, dishwasher-safe with the right ink, and the substrate behind nearly every premium metallic finish you have ever held.

Polyethylene Terephthalate Film

What is Vinyl?

The workhorse of the sticker world. Affordable, versatile, conforms to compound curves, accepts every print method — and the substrate behind almost every Etsy run worth its salt.

Polyvinyl Chloride Film (PVC)

What is Adhesive?

The thin polymer film between the face stock and the liner. Responsible for more peeling complaints than the face material itself. Four chemistries, four permanence levels, a hundred ways to get it wrong.

Pressure-Sensitive Adhesives (PSA)

What is Liner?

The backing you throw away. Invisible, over-engineered, and responsible for more print-shop jams than anything else in the build. Five materials, three coatings, one set of decisions that decide whether the label runs clean.

Release Paper · Release Film

What is Coated Paper?

The premium paper face. A mineral coating holds ink on the surface for razor-sharp type and photo-grade images — perfect for wine and perfume, useless once it gets wet without help.

Clay / Calcium-Carbonate Coated Label Paper

What is Kraft?

The craft-honest brown paper. Signals handmade, organic and sustainable — and wicks water the instant it meets it. Beautiful in a dry pantry, wrong in a fridge.

Unbleached Wood-Pulp Paper

What is Synthetic Paper?

Paper to the touch, plastic in the wash. Waterproof and tear-proof, it is what outdoor menus and waterproof manuals are made of.

Yupo · Teslin · Synaps

What is Thermal?

The barcode-and-receipt family. Direct thermal is cheap and fades; thermal transfer melts a ribbon on for real durability. Pick the wrong one and your label is black by August.

Direct Thermal · Thermal-Transfer Facestock

What is Destructible?

The self-destructing label. Try to peel it and it shatters — irreversible proof that someone tried. The face of every warranty seal and asset tag.

Eggshell · Tamper-Evident Material

What is Metallized Film?

A whisper of aluminium for a barrier and a mirror. The high-gloss silver of beer and spirits — and a real oxygen-and-moisture shield at a fraction of foil-lamination cost.

MetPET · MetOPP

What is Polycarbonate?

The control-panel overlay. Impact-resistant, optically clear, printed on its underside so the graphics never wear off — built for buttons people press ten thousand times.

Lexan Overlay Film

What is Polyimide?

The extreme-heat specialist. Survives the solder reflow oven, the autoclave, and the cold of space. Overkill for anything that is not genuinely on fire.

Kapton Film

What is Die-Cutting?

How the sticker gets its shape. Three cuts, one liner, and the single decision that separates a peel-and-stick sheet from a jam-prone mess on a high-speed line.

Kiss-Cut vs Die-Cut vs Through-Cut

What is Lamination?

The clear film laid over the print. It buys years of outdoor life, shields ink from UV and scuffing, and turns a fragile label into one that survives the warehouse — for a few cents and one specification decision.

Overlaminate & Topcoat Film

What is Permanent vs Removable?

The most misunderstood word on a spec sheet. “Removable” does not mean weak, and “permanent” is not always what you want — the choice turns on the surface and how long the label lives there.

Adhesive Permanence

What is GSM & Caliper?

Two numbers that quietly decide whether a label conforms to a curve, feeds through a machine, or lifts at the edges. Buyers ignore them; converters live by them.

Thickness & Weight of a Label

What is Roll vs Sheet?

Not a cosmetic choice. One format runs on any office printer with no minimum; the other unlocks lamination, low unit cost, and every automatic applicator on the planet.

Roll Label vs Sheet Label Formats

What is Thermal Transfer vs Direct Thermal?

One prints with a ribbon and lasts years; the other prints without one and fades in months. Confuse them and you either overpay or watch your barcodes disappear.

The Two Ways a Barcode Printer Makes a Mark

What is Varnish?

A liquid coat, not a film. It receives the ink, protects the print, and — in its most striking form — puts glossy artwork against a matte background on the same label.

Topcoat, Overprint Varnish & Reverse UV

What is MOQ?

The number that stops many first orders — and the one most open to negotiation once you know why it exists. Setup cost, not stinginess, sets the floor.

Minimum Order Quantity

What is Waterproof vs Water-Resistant?

One word, three different jobs. A splash, a soak, and a season outdoors each demand a different construction — and the adhesive can sink the label even when the face survives.

Three Levels of Water Protection

What is Hot Stamp vs Cold Foil?

Both lay down a metallic shine; one uses a heated die, one uses UV glue at room temperature. The heat decides which substrates are in play and how fine the detail can go.

Two Ways to Put Metal on a Label

What is Incoterms?

The three or four letters in a quote that decide who pays the freight, who clears customs, and who eats the duty. Get them wrong and a “cheap” quote becomes an expensive surprise at the port.

EXW · FOB · CIF · DDP

What is Low-Surface-Energy Plastics?

The reason a perfectly good sticker peels off an HDPE bottle in days. Some plastics chemically repel ordinary adhesive — and the fix is chemistry, primer, or a treated surface, not more pressure.

LSE — PP, PE & Untreated Polyolefins

What is Surface Preparation?

The single most common cause of adhesion failure is not the adhesive — it is what was on the surface underneath it. Clean, dry, room-temperature: three conditions that decide whether the label holds.
