Temperature: 90–110°C (adjust within this range)
Adjustment Criterion: Stamping temperature should be adjusted between 90°C and 110°C, ensuring the foil can be easily scratched off the substrate after transfer. Conduct sample
tests to determine the optimal setting.
Note: All three SCF models are designed for hot stamping processes where the foil is transferred to the substrate and then hidden beneath a scratch-off coating. The key performance indicator is
reliable adhesion combined with clean scratch-off behavior.
Security labels and tamper-evident seals for pharmaceutical blister packs, electronics warranties, and luxury authentication
Promotional scratch cards, gift vouchers, membership cards, and instant-win lottery tickets
Anti-counterfeiting tags for automotive parts, cosmetic cartons, and premium spirits packaging
Flexible packaging overlays requiring concealed PIN codes, serial numbers, or one-time coupon reveals
All three SCF models are purpose-built for hot stamping processes where the foil transfers onto the substrate and sits beneath a functional scratch-off coating. The critical performance indicators are dependable adhesion during logistics and clean, residue-free scratch-off action for end-users. Always conduct production trials with your actual equipment, dwell time, and ambient conditions before full-scale runs.
For the Scratch Off Foil requirements beyond standard options, Kalefu Packaging provides custom roll widths, splice-free lengths, and adhesion tuning for specific surface treatments. Direct engineering support is available for die optimization, substrate testing, and formulation adjustments to match unique production constraints.
