Three main methods to add a metallic finish to cosmetic packaging boxes are: 1. Foil stamping, which uses heat and pressure to transfer a thin aluminum coating from foil to paperboard. 2. Metallic inks printing, which uses metallic powders or newer technologies to print shimmering inks. 3. Metalized paperboard printing, which applies a metallic coating directly to paperboard through vacuum metallization or laminating a metal film.

- 1. Three Methods to Add the Metallic Finish The metallic gold/silver finish is a great way to add the impressive and luxury quality feel to the cosmetic packaging box SUGENG ENDARSIWI-2024
- 2. • Foil stamping • Metallic Inks Printing • Metalized Paperboard Printing Three Methods to Add the Metallic Finishing:
- 3. • Foil stamping • Foil stamping has 2 categories: • hot foil stamping • cold foil ================================ • Hot Foil The metallic finish is created by transferring a very thin layer of aluminum coating on the foil paper to the intended paperboard by using heat and pressure. The heat activates separation coatings and adhesive coatings that affect the permanence of the resulting finish on the paper box.
- 4. • Cold Foil • Cold foil has been growing dramatically recently both in brand owner use and in technical development. • The metallic coatings from the film will only transfer to the paper sheet where the adhesive has been applied. The adhesive is cured to set the metallic look with permanence to the sheet so that additional colors of ink can be applied directly to the metallic surface. • With regard to the metallic effect, the cold foil can not rival the hot foil stamping at present.
- 5. • Metallic Inks Printing • Two types of technology are widely used to produce metallic inks and coatings. Of the two, the oldest technology dates back several decades and has traditionally been referred to as metallic powder technology. • The finished results of products using metallic powder suffered from a number of shortcomings. • Reflectivity and brilliance was dull at best and resistance levels to in-use exposures were often a risk.
- 6. • Metalized Paperboard Printing • The metallic effect of this method is realized by the natural metallic color of the metalized paperboard. • During the printing process, the CMYK inks are only printed on the text area and the colored area. While the transparent area on the artwork has no inks applied on the metalized paperboard. • Generally, there are 4 kinds of metalized paperboard used. • The metalized paperboard can be glossy or matte.
- 7. Aluminum Foil Board Laminates Foil board laminates were among the first type of processes for creating a metallic look on paperboard. This product is produced by physically laminating with an adhesive – a sheet of aluminum to a sheet of paper. The manufacturing process is very efficient, however there are relatively few companies involved in the production of aluminum foil board globally. The finished product usually has the higher grammage value than other metallic decorating alternatives.
- 8. • PET/BOPP-Metalized Paperboard • The product is produced by metalizing the PET or BOPP film of choice and laminating the metalized film to the paperboard with an adhesive.
- 9. Transfer Metalized Paperboard Transfer metalized film is produced to create a metalized surface on thinner caliper papers and when weight reduction in an application is desired. The manufacturing process is similar to cold foil transfer processes, but on a larger high-volume scale. A film is coated and metalized to allow the layer of aluminum metalizing to be released away. This metalized film is placed in contact with a paper or paperboard that has an adhesive applied to it. The adhesive can be applied in a flood manner, covering all of the sheet, or a discrete manner, allowing selective elements to transfer. The paper and the film is then stripped away releasing the metallic aluminum, which remains on the sheet only where the adhesive has been applied. The finished product is among the lightest weight options for metallic finishes.
- 10. Direct Metalized Paperboard Direct metalized boards and papers are typically produced using vacuum metallization which deposits a very thin vapor of aluminum directly onto the coated paperboard. The resulting aluminum layer will take on the attributes of the paper fibers or surface profile. Very smooth papers will provide higher reflectivity than less smooth papers. Direct metalized papers and boards are most commonly coated with a clear coating. The coating will provide attributes for printing, exposure resistance features and final finish to the paper. The coatings can be cellulose-based or acrylic- based. Application methods will cure using oxidation, ultraviolet light or electron beam. It is one of the lightest weight options.
- 11. How do print offset printing on metalized paper? need a UV dryer / Lamp (because it is impossible for the ink to dry naturally on metallized sheet) There are 2 options to print on metallized sheet: 1. Buy the paper sheet and laminate it with metallic film, now when you buy the film, ask your vendor to give you a ready to print film. If you're already getting that its no problem. 2. But if not , then you need to a base coat (Primer Base) run on your offset machine (offline) for ready to print sheet: First run: White ink opaque Second run :White ink transparent (if required) Third run : 4 colour uv printing Fourth run : Top Coating varnish (if required) All these processes will require a UV dryer (UV Lamp). * UV Cured ink can not dry with IR * Even normal ink with an IR on a metallized sheet (need aging time).
