Better hold & shinier gloss.

Inline finishing with cold foil is bang on trend...

After all, this method doesn’t just create striking effects on packaging – it is also much faster, more flexible and more cost-effective than hot foil. Cold foil is also more suitable for recycling than metalized film-laminated PET packaging, as the aluminum pigments that transfer onto the substrate are easier to remove in the disposal process.

However, although global consumption of cold foil is rising, the technology has so far barely made any headway in sheetfed in-mold and blow-mold labeling.

This is due to insufficient process stability, which is an irritating problem for print shops and their customers. FoilStar Cure from Heidelberg primarily resolves this issue by using dedicated LED UV cold foil adhesives and inks and Dry Star LED UV dryers. Heidelberg has optimized web guidance on the FoilStar, which can be retrofitted to any appropriately configured press, so that the foil web stays on the impression cylinder for longer.

This results in pigments that are more adhesive and glossier, and high process stability, which opens up new possibilities for in-mold label printers in particular.
