PremiumBespokeArtisanLuxuryLabels Stickers

Functionally none — both are printed adhesive-backed material. The distinction is how they are used and supplied.

Labels are typically supplied on rolls for machine application and carry product information: ingredients, barcodes, batch codes, regulatory content. Stickers are usually supplied in sheets or as individual die-cut pieces, applied by hand, and serve promotional or decorative purposes. The specification conversation is the same for both: facestock, adhesive, and how it will be applied.

Die size, facestock, adhesive, core diameter, outer diameter, unwind position and gap distance.

The last four are machine requirements rather than design choices. Unwind position describes which way the label faces coming off the roll — there are eight standard positions, and an applicator built for one will jam on another. Core size is usually 3 inches for industrial applicators and 1 inch for desktop printers. Getting these wrong produces a correct-looking roll that cannot be used.

Film facestocks — BOPP, polypropylene, vinyl and polyester — are inherently waterproof. Paper labels are not, regardless of coating.

But waterproofing is a system, not just a facestock. The ink must be water-stable, a laminate protects it from abrasion, and the adhesive must hold on a wet or chilled surface — standard permanent adhesives lose grip on condensating containers, which is what freezer-grade and wet-apply adhesives exist for. The weakest of those four layers determines the result.

Almost always a surface-energy problem. HDPE, polypropylene and recycled kraft are low-energy or textured surfaces that standard adhesives struggle to bond to.

The fix is a high-tack adhesive formulated for those substrates. The failure is often delayed — a label that looks fine leaving the line lifts at the edges days later in a customer's cupboard, which is why testing on the real container, filled, at realistic temperature, and left for a week is the only reliable validation.

Kiss-cut cuts through the sticker but not the backing. Die-cut cuts through both, so the sticker and its backing share the same shape.

Kiss-cut leaves a border of backing around the design, which makes peeling easy and sheeting simple — it is the standard for merchandise and pack-in stickers. Die-cut has no surrounding border and looks better as a standalone object, at a slightly higher handling cost. Kiss-cut on a die-cut backing is the premium retail format, giving a shaped backing with a shaped sticker inside it.

Cast vinyl with a UV laminate typically lasts five or more years outdoors; calendered vinyl without lamination may fade within a season.

Two factors drive this. Cast vinyl is poured rather than rolled, so it has almost no internal stress, conforms to curves and does not shrink — calendered vinyl does all three and lifts at the edges on curved surfaces. The UV laminate is what prevents fading; unlaminated vinyl in direct sun goes chalky far faster than buyers expect.

Product identity, net contents, ingredient declaration in INCI names, and a responsible person's US contact details.

Under 21 CFR 701.3 the ingredient list must be at least 1/16 inch in height, reducible to 1/32 inch only where the total labeling surface is under 12 square inches. Since December 2024, MoCRA has required a US address, phone number or electronic contact for adverse event reports. A PAO symbol appears where shelf life exceeds 30 months.

Digital label printing has effectively no meaningful minimum — runs of a few hundred are routine — while flexographic printing generally starts around 5,000.

That difference is plate cost. Digital has no plates, so a hundred labels and a thousand cost roughly proportionally. Flexo pays plate setup per colour per version, which is expensive at low volumes and negligible at high ones. Because labels are cheap per unit, the price break comes earlier and harder than in most packaging.
