Technical Data

Cold Foil Process:

In cold foil stamping, a photopolymer plate defines the desired design. UV-curable adhesive is applied only to the image area, and the foil is then pressed against the substrate. The foil adheres to the adhesive under UV light, transferring the image with precision and brilliance.

 

Main Characteristics:  

Sharp detail and consistent foil transfer

Excellent performance on paper and laminated films

Works on printed, unprinted, and coated surfaces

Over-printable 

 

Recommended Applications:  

Adhesive paper or laminated films of labels for flexographic using, especially in industries such as cosmetics, personal care wine and beverages, bath & beauty products, etc.
