HOT STAMPING FOIL

 

 

Hot stamping foil is intensively used in printing and packaging industry, like graphic industry, textile industry, security applications, and etc. Typical decorative applications of hot stamp foils include greeting cards, book covers and packaging media, such as labels and folding cartons, wood, leather, textile, etc. Transfer foils can also be found embellishing writing instruments, cellular telephones and cosmetics. In these cases, the hot stamp foils are primarily for promotional purposes or aesthetic appeal. Foil stamping is environmentally friendly due to it being a dry process. It does not use solvents or inks and does not create any harmful vapors.

 

Hot stamping is the process of transferring a very thin coating (typically metallic) onto paper or plastic through a combination of heat and pressure. Hot stamping foils are built up in layers and the foils are processed on a thin film, so the manufacturing skill involved is very complex. Foils start with a carrier film, onto which are placed layers of embossing, metallization, release, protection and an adhesive layer to bond it to the item being protected. If an attempt is made to remove all or part of the layers, this tampering becomes visibly evident.

Foil is an extremely thin polyester film material containing a dry pigment that is transferred to substrate (such as paper) by the use of heat and pressure.

 

Foil composition:

•  Film carrier: The thinner the carriers (often polyester) while all other things being equal, the faster the foil will transfer
• Release Coat: Allows the other layers to release from the film carrier upon application of heat &/or pressure in which this layer affects whether or not a foil is suitable for fine copy or heavy coverage. Lacquer, Tie or Color Coat provides a hard abrasion resistant surface to the foil when applied and carries the color tint in the form of pigments or dyes which is required to make gold or other colored metallic because the metallic layer is always made from aluminum.
• Metal Coat: Generally composed of aluminum to provide the reflective qualities and opacity desired in metallic foils.
• Adhesive or Sizing Coat: The final layer in the foil construction is the sizing which serves to bond the foil to the substrate being stamped.

 

A successful hot stamping job is directly related to the quality of the original artwork. In order to insure the highest quality reproduction of an imprint, the original artwork should be “camera-ready”. The better the artwork at the beginning, the better the imprint reproduction result. The key to a successful hot stamping job is threefold; the first is creating a fixture to support the part firmly under the decorating area. Second, the fixture must also position the part for repeatability of the graphic location. And third, the fixture must allow the operator to easily load and unload the part from the fixture.
