Structure of Foil

Here at Foilco we understand the different layers found within a foil structure.

Using our years of expertise and knowledge we have put together a list, breaking down the structure of foil. Our in-depth description on the different layers of a foil will give you a deeper understanding as to how foils are created and how they function.

The Structure of Foil

Usually, a 12 Micron Polyester, this material offers the most heat stability and the carrier film is the most robust for the coating process.

Allows the hot stamping foil to release from the film carrier upon application of heat & pressure. This layer affects whether or not a foil is suitable for fine detail or large area coverage.

Gives colour to the final product. Dyes are combined with the lacquer coat. This is translucent, which allows the aluminium layer to show through, giving a metallic colour. Lacquer is required to give foils a smooth glossy finish, this layer is not present in pigments foils.

Vacuum Metallised Aluminium layer to provide complete opacity. This process of metallisation is only present in metallic foils. This is needed to give the mirror-like effect.

The final layer in the foil construction is the sizing/adhesive which serves to bond the foil to the substrate being stamped. Different adhesives are needed on foils to suit the different materials – this defines the grade.
