Die-Cutting?

Die-cutting is the step that gives a label its outline. A shaped blade — the die — presses through the material so the finished label can be peeled and applied. There are three cut depths, and choosing the wrong one is a common, avoidable error.

Kiss-cut cuts through the face and adhesive only, leaving the liner intact. This creates a protective backing around the design, makes the label easy to peel without touching the artwork, and allows several labels to sit on one sheet. Die-cut (full-cut) cuts through both the material and the liner, following the exact shape of the design — the result is a finished, standalone label with no surrounding waste. Through-cut uses interior cuts to create negative space inside the design so the surface behind shows through.

Two tooling routes exist, and the economics diverge sharply by volume. Steel-rule dies carry a one-time tooling cost that must be covered regardless of order size; it is quoted separately and amortised over the life of the die. Commonly available standard shapes — rounds, ovals, rectangles, squares — have no tooling cost because the dies already exist.

For lower volumes or prototype shapes, rotary laser die-cutting avoids a physical die entirely, at the cost of slightly slower run speeds and a modest per-unit premium. A truly custom outline is more economical at higher volumes; a standard die-size minimises tooling investment. When ordering a custom shape, confirm the tooling fee up front, who owns the die, and whether it is stored for reorders.

Die-cut individual stickers suit promotional handouts and any product that ships as a standalone shape. Kiss-cut is the choice for sticker packs, planner sheets, and designs with delicate elements that would tear if peeled directly. Through-cut serves decorative applications where negative space is part of the design.

For automatic labelling lines, die-cut depth interacts with the liner: a shallow die that leaves the liner’s fibres intact is preferable to a deep die that scores through it and weakens the web.

Cut depth is a web-strength decision. On high-speed applicators, a die that penetrates too far into the liner robs it of tensile strength at the cut line, and the web breaks under dispensing tension. The production-validated fix is a heavier liner — stepping up glassine weight — or a coated liner for the fastest lines. Both cost more; confirm the trade-off against your run length.

Heat changes the cut. In hot weather the adhesive softens, and stripping the waste matrix (the surrounding lattice removed after cutting) becomes difficult — the matrix tears or leaves residue on the liner. Scheduling cutting for cooler hours, air-conditioning the die area, and running slower all help. Expect slightly longer die-cutting lead times when ordering in summer.
