A Simple Guide to Cold Foil Stamping

Cold foil stamping is a premium inline printing process. This process bonds metallic foil to a substrate using a UV cured adhesive. The process is done at room temperature. That means it does not need any heated die or engraved tools. 

The process transfers the thin layer of a metallized polyester foil onto the mylar substrate using a UV curable adhesive. This adhesive is applied at room temperature using a printing plate. The adhesive is printed onto the substrate in the shape of the image where the foil needs to adhere, not onto a metallic image 

Then to cure the adhesive quickly a UV lamp is used and the extra foil is peeled away. It works exceptionally well on flexible packaging solutions such as Mylar bags. 

Why Choose Cold Foil Stamping for Mylar Bags?

Cold foil stamping is a modern printing method that uses a UV curable adhesive to transfer metallic foil onto the mylar. It doesn’t use heat to transfer metallic or gold foil like hot foil stamping. It is an ideal choice for Mylar bags since it applies excellent and high shine metallic finishes on them using UV curable adhesives.

They are highly compatible with thin and heat sensitive plastic films like mylar bags. It does not cause the material to melt or warp during the foil stamping process. 

Here are the key reasons to choose cold foil stamping for Mylar bags:

• It preserves mylar bags' structural integrity. No heated plates or dies are pressed onto the film which ensures the mylar remains completely intact. 

• Cold foil stamping offers design versatility. It allows for intricate, fine details, and overprinting of CMYK inks directly on top of the foil.
