Scratch-Off Foil for Hot Stamping: A Complete Buyer's Guide for Lottery, Card & Label Manufacturers

If you print lottery tickets, prepaid cards or promotional scratch cards, the foil you choose determines whether your finished product looks professional — or ends up with flaking, streaking, or codes that scratch off too easily (or not at all). This guide breaks down what scratch-off foil for hot stamping is, how it works, and the technical factors that separate reliable suppliers from risky ones.

What is scratch-off foil?

Scratch-off foil is a specialised hot stamping foil designed to conceal printed information — a PIN, a code, a barcode, a "win/lose" message — until the end user physically scratches it away with a coin or fingernail. Unlike decorative gold or silver stamping foils, its job is not to look shiny; it is to release cleanly and completely, every time, without damaging the print underneath.

The foil is applied using standard hot stamping equipment: heat and pressure transfer the masking and adhesive layers from a carrier film onto the printed substrate — typically coated paper, cardstock or PVC. Any flatbed or rotary press works, including our XG1080G fully automatic hot stamping machine.

How it works: the layer structure

A scratch-off foil has four functional layers working together:

• Carrier film — the BOPET base (12 / 19 / 23 µm) that carries the foil through the stamping press and is stripped away after transfer.
• Release coating — engineered so the top layers separate cleanly under a fingernail scratch without tearing or leaving film residue.
• Opacity / masking layer — a dense, light-blocking silver or gold pigment layer that fully hides the print underneath.
• Heat-seal adhesive — bonds the whole stack to the substrate during hot stamping.

Getting the balance right between these layers is the difference between a card that scratches off in one smooth motion and one that either will not come off or flakes apart in the box during shipping. For a refresher on the underlying process variables — temperature, dwell and pressure — see our hot stamping process guide.

Where scratch-off foil is used

• Lottery and instant-win tickets — the highest-volume application, where consistency across millions of units matters most.
• Prepaid and gift cards — concealing the redemption code or PIN.
• Loyalty and promotional scratch cards — retail and F&B "scratch to win" campaigns.
• Security labels and tamper-evident seals — often paired with anti-counterfeit security foil to prove a package or document has not been accessed.
• Cosmetics and consumer goods — scratch-to-reveal promo codes on secondary packaging, sometimes combined with holographic foil for added visual security.

What to check before you order

Sourcing scratch-off foil from China

China-based hot stamping foil manufacturers, including All-in Pack, supply scratch-off foil to lottery operators and card converters across 60+ countries. When evaluating an overseas supplier, prioritise:

1. Availability of a technical data sheet covering thickness, release spec and adhesive type.
2. Willingness to send free or low-cost samples before a full order.
3. Custom slitting to your press's roll width and core size.
4. A track record with security or financial-sector clients, given the tamper-evident nature of the application.

If you are also comparing decoration methods for the rest of the card or ticket, our hot vs cold foil stamping comparison covers the cost and tooling trade-offs.

Final thoughts

Scratch-off foil looks simple on the surface, but the release layer, opacity and adhesive chemistry all have to be precisely tuned to your substrate and press. Testing samples before committing to a production run is the single best way to avoid costly reprints.
