Foil stamping is a finishing process that presses a thin metallic or pigmented film onto a box surface using heat and a metal die, leaving a shiny, flat mark in gold, silver, copper, or a color. The Best Price Boxes prints custom packaging with no minimum order and a price-beat guarantee, and you can ask us to quote foil on your design.
How hot foil stamping works
A metal die, usually brass or magnesium, is engraved with your artwork in reverse and heated. A roll of foil, which is a carrier film coated with a pigment layer and a heat-activated adhesive, runs between the die and the box. The die presses down for a split second, the adhesive bonds the pigment to the paper, and the carrier peels away. The mark sits slightly flat and sharp, often with a faint impression. Foil can be combined with embossing so the metallic area is also raised, which is how many luxury logos are made.
Hot foil versus cold foil
Cold foil transfers pigment with a UV-curing adhesive printed on press, without a heated die. It suits large runs and fine halftone effects. Hot foil gives a denser, mirror-like finish and is the usual route on rigid boxes and small custom runs, because the die is made once and used repeatedly. Holographic foil is a patterned variant that shifts with the angle of the light; see our holographic foiling boxes.
Design rules that save a reprint
Foil likes bold shapes: logos, monograms, borders, and large type. Very thin lines, small serif type, and tight gaps between letters can fill in. Keep detail at about half a point or heavier and leave breathing room. Foil bonds best to uncoated or lightly coated stock, and it does not stick well over heavy ink coverage or some varnishes, so keep the foil area clear of both. Supply foil artwork as a separate vector layer, in one flat color, so the die can be made accurately.
Where foil earns its place
Foil reads as premium, so it shows up on cosmetic cartons, candle boxes, gift sets, and cigar boxes. It works well on rigid boxes, where the thick wrapped board gives a smooth, stable surface. On a tight budget, one small foil mark on a plain box often does more than full-coverage printing. Foil is a poor fit for large solid areas, which can show wrinkles and uneven coverage.

Getting it quoted
Send your logo as a vector file, the box style, size, and quantity, even if it is one. We confirm foil colors and placement for your spec, then send a dieline and quote. Have a written quote from another supplier for the same job? Send it and we will beat it. Start on the request a quote page.
Questions buyers ask
What is the difference between foil stamping and metallic ink?
Foil is a solid metallic film pressed onto the surface and reflects light like real metal. Metallic ink is printed pigment with metal flakes, so it looks softer and duller. Foil is brighter, but it needs a die and cannot cover fine halftones.
Can I add foil to a small order?
Often yes, since we have no minimum order. A foil die is a one-time setup for each design, so very small runs carry more setup per box. Ask us to quote your exact spec.
Does foil work on kraft or dark stock?
It can, but the result changes. Opaque foils cover dark stock well, while thin or transparent foils pick up the color underneath. Textured kraft can make fine detail patchy. Ask for a sample before committing.
What artwork file does foil need?
A vector file in a single color, such as an AI, EPS, or PDF, with the foil areas on their own layer. Send it with the box style and we will prepare the die artwork.
