A sticker that takes four seconds to peel and place is fine at ten bags an hour and a bottleneck at two hundred. Format decides that more than the artwork does. This guide compares roll labels and sheet stickers, explains the cutting terms suppliers use, sets out how shape and size interact with the surface, and shows how to work out labels per roll so that rolls fit the dispenser or machine. It belongs to the custom printed stickers and labels hub.
Which is better, roll labels or sheet stickers?
Roll labels are better for repeat application at speed, by dispenser or machine. Sheet stickers are better for occasional hand application, mixed designs and short campaigns. The deciding factor is usually handling time rather than label price: if staff apply the same label many times a shift, a roll pays for itself in labour.
| Factor | Roll labels | Sheet stickers |
|---|---|---|
| Application | Peeled from a dispenser or applied by machine | Peeled by hand from a sheet |
| Best volume pattern | Repeated use of one or a few designs | Occasional use, many designs or shapes |
| Speed | Fast; consistent label position with an applicator | Slower; depends on staff |
| Mixed designs | One design per roll (or several in a run, split into rolls) | Several designs or shapes can share a sheet |
| Storage | Compact; each roll needs a clear design code | Flat; sheets can curl or lose labels at the edge |
| Printing at the user | Thermal printers print variable data onto roll labels | Office laser or inkjet printers print onto sheets |
| Typical packaging use | Bag seals, box closures, food product labels | Gift packs, sample packs, mixed promotional stickers |
For takeaway, bakery and delivery packs, roll is the usual format. Sheets suit retail wrapping, sample packs and craft or event use where each sticker is placed deliberately.
What do kiss-cut and die-cut mean?
A kiss-cut cuts through the face material and adhesive but leaves the backing liner whole; a through-cut (full die-cut) cuts through everything, making individual pieces with no liner. Most stickers and labels on rolls and sheets are kiss-cut so they stay on a carrier until applied.
Suppliers use "die-cut sticker" loosely. Clarify which you mean:
- Kiss-cut label or sticker on a roll or sheet: face cut, liner intact; the usual packaging format.
- Kiss-cut custom shape on a sheet: each design cut to its own outline, still on the shared liner.
- Through-cut sticker: cut through the liner too, for single loose pieces; uncommon in packaging.
- Perforated sheet or roll: perforations between labels so they tear apart, sometimes used for sets.
After cutting, the waste around the labels (the matrix) is stripped away. Narrow necks or thin points in a custom shape can tear in the matrix, so the cutting outline should avoid sharp inner corners and slender features.
Round, square, oval or rectangle: which shape suits the pack?
Round stickers apply fastest and lift least, oval suits extra width, squares and rectangles cover more of a flap or seam, and custom shapes brand the sticker itself. Shape should follow the surface it bridges and the content it carries.
| Shape | Strength | Limit | Typical use |
|---|---|---|---|
| Round | No corners to lift; easy to place | Less area for text | Bag seals, jar lids, box closures |
| Square | Fits box corners and flaps | Corners lift without a radius | Gift wrap, tissue seals, small boxes |
| Oval | More width than a circle with soft edges | Orientation matters | Bottles, jars, seals needing width |
| Rectangle | Best for text and bars | Long edges can lift on curves | Ingredient, date, address and strip seals |
| Custom shape | Brand recognition | Cutting tool; fragile points | Logo outlines, product shapes |
Square and rectangular labels should have a small corner radius, because sharp corners snag and start to peel first. A radius of a couple of millimetres is a common starting point for small labels; confirm with the supplier's cutting tool options.
How large should a packaging sticker be?
Size for the job, not the artwork: a seal must bridge the opening with margin on each side, and an information label must hold the required text at a legible size. Start from the surface and test, rather than from a catalogue size.
Rules of thumb as starting points:
- Bag-neck or flap seal: the sticker should bridge the fold and overlap the pack on both sides with enough margin to grip. Test one size up and down on your actual bag.
- Curved surfaces (tubs, bottles): a label that is too wide for the curvature wrinkles. Keep the height within the flat part of the surface unless the label is film and conforms.
- Text labels: size is set by the text and the minimum letter height needed. For food information in the EU, Regulation (EU) No 1169/2011 sets a minimum font size, covered in food packaging labels.
- Round logo stickers: typical diameters run from small seals of a few centimetres to larger closures; the pack decides, not the catalogue.
Metric and US dimensions both appear in orders: 50 mm is about 2 inches, and 76 mm is 3 inches.
What do roll specifications include?
A roll specification names the core size, the outside diameter, the unwind direction, the gap between labels and the number of labels per roll. These decide whether the roll fits your dispenser or machine, and are the details most often missing from an enquiry.
| Specification | What it is | Typical values |
|---|---|---|
| Core size | Inside diameter of the cardboard core | Commonly 25 mm (1 in), 40 mm (1.5 in) or 76 mm (3 in) |
| Outside diameter (OD) | Diameter of the full roll, limited by the dispenser or machine | Depends on the equipment; ask for its limit |
| Unwind direction | Whether labels face outward or inward and which edge leads | Specified by number or diagram; must match the machine |
| Label gap | Space between labels along the liner | Often 2 to 3 mm; the sensor needs a clear gap |
| Label pitch | Label length plus gap | Used to calculate labels per metre |
| Labels per roll | Quantity wound on one core | Set by OD and label pitch |
| Web width | Width of the liner | Slightly wider than the label |
Equipment determines most of these values, so ask for the dispenser or applicator's maximum OD, core size and unwind direction before choosing a roll size.
How many labels fit on a roll?
Labels per roll depends on label pitch, core size and the thickness of the label and liner together. A quick calculation is roll length = number of labels x (label length + gap), then outside diameter from the length.
The approximate outside diameter is OD = square root of (core² + 4 x length x thickness / pi), with length and thickness in millimetres. Strictly, "core" here is the core's outside diameter, slightly larger than the nominal inside diameter, so the result is a slight underestimate. Total thickness is face material plus adhesive plus liner; for paper-based constructions it is often roughly 0.1 to 0.2 mm, but check the datasheet.
Worked example (indicative):
| Item | Value |
|---|---|
| Label | 50 mm round, 3 mm gap, so 53 mm pitch |
| Labels | 1,000 |
| Length | 1,000 x 53 mm = 53 m |
| Total thickness (assumed) | 0.12 mm |
| Core | 76 mm |
| Approximate OD | about 118 mm |
On a 76 mm core, a roll with a 150 mm maximum OD would hold roughly two thousand of these labels at the same assumed thickness. Treat the figures as planning numbers; the manufacturer gives the real count per roll for the chosen material.
What do dispensers and applicators need to know?
The dispenser or applicator limits label size, roll size, label gap and unwind direction, so give the machine details when you ask for a quote. A simple hand dispenser accepts a range of widths and OD; an automatic applicator needs a consistent gap and sensor-friendly liner.
- Manual dispensers peel one label at a time and suit counters and small kitchens.
- Semi-automatic and automatic applicators place labels at a set position; the liner must be a consistent opacity so the sensor reads the gap.
- Variable-data thermal printers (for dates and weights) take specific core sizes and need materials suitable for thermal transfer or direct thermal printing; a branded label printed in advance and a variable label printed on site are often two separate rolls.
- Application position matters for tamper evidence and legibility; see tamper-evident takeaway bags where a seal must show opening.
Tell the supplier the dispenser model or its specifications, or send the machine datasheet.
What sheet sizes and layouts are common?
Sheet stickers are typically cut from standard sheet sizes: A4 (210 x 297 mm), A3 and SRA3 (320 x 450 mm) in Europe and the UK, and US Letter (8.5 x 11 in) in the US. Labels per sheet depends on size and layout, and sheets can hold several designs.
Sheets suit hand application of mixed stickers: a sample pack with several logos, a sheet of seals for gift wrapping, or a promotional set. Sheets also suit office printing of short runs, but a manufacturer prints finished branded sheets with proper registration and colour. Allow a margin around the layout for cutting tolerances, which the manufacturer confirms at quotation.
What to send for a quotation
Send the use, the shape and size, the format and the equipment, so each supplier quotes the same thing:
- Use and surface, and the application method (hand, dispenser, machine)
- Shape and size in mm (and inches if useful), with corner radius if square or rectangular
- Format: roll or sheet
- For rolls: core size, maximum OD, unwind direction, label gap or machine datasheet, labels per roll or total quantity
- For sheets: sheet size, labels per sheet and number of designs
- Face material and adhesive, or the conditions so the supplier can propose them (see sticker and label materials)
- Print and finish requirements (label finishes)
- Artwork status; the packaging artwork guide explains cutting lines, bleed and proofs
- Annual quantity per design
Send the list through the contact page; formats, tooling and tolerances are confirmed at quotation and technical review. For the wider pack context see the packaging RFQ guide.
