Fóliaszer

Fóliaszer is a term used in Hungarian technical language to designate a device that applies, transfers, or seals foil onto a substrate. In English-language packaging and printing contexts the function is described as a foil applicator, foil laminator, or hot foil stamping equipment. The category encompasses a range of machines from hand tools to fully automated systems used in manufacturing, packaging, labeling, and decorative arts.

Principle of operation involves feeding a sheet or roll of foil together with the substrate, aligning them, and transferring the foil to the substrate surface through pressure, heat, or adhesive action. Cold-foil processes rely on pressure and an adhesive to carry the foil onto the surface, often with UV or thermal curing. Hot-foil stamping uses heated dies to transfer metallic or pigmented foil in a single impression. Some systems combine multiple steps, such as pre-inking, foil transfer, and post-press finishing, to produce durable decorative effects.

Types range from manual hand-held devices for crafts and small-scale work to desktop laminators and roll-to-roll industrial presses for high-volume production. Configurations may be roll-to-roll, roll-to-sheet, or flatbed, depending on substrate format and production requirements.

Materials used include various metallic and pigmented foils, holographic foils, and specialty laminates, compatible with substrates such as paper, card, plastics, and packaging films. Common applications are decorative packaging, branding and labeling, electronics shielding coatings, and art projects where foil finishes are desirable.

Safety and maintenance considerations focus on handling heat elements, avoiding foil tears, and regular cleaning of rollers and dies to maintain image quality and machine performance.
