Make Cylinder (Gravure Engraving)
-
A steel cylinder is engraved with the desired pattern using laser or chemical etching. This cylinder ensures high-precision printing on the film.
-
-
Printing (Gravure/Flexographic Printing)
-
The engraved cylinder transfers the design onto a PET/OPP film using solvent-based or UV-curable inks. Special release inks are applied to facilitate later heat transfer.
-
Vacuum Metallization (Aluminum Coating)
-
The printed film passes through a vacuum chamber, where aluminum is vaporized and deposited onto the surface, creating the shiny metallic film effect.

-
Drying & Curing
-
The metallized film is dried in an oven to remove solvents and enhance adhesion. Proper curing ensures scratch and fade resistance.
-
-
Die-Cutting (Punching or Slitting)
-
The film is cut into sheets or rolls using precision die-cutting machines, making it ready for application on PP plastic fruit boxes or other substrates.
-
-
Quality Inspection (QC Testing)
-
Each batch is checked for defects (e.g., uneven coating, scratches, misprints) to ensure durability, adhesion, and visual perfection.
-

-
-
Packing & Shipping
-
The approved heat transfer film shinny rolls/sheets are packed in protective materials and prepared for delivery.
-
-
This process ensures a high-quality metallic film with excellent reflectivity and adhesion, ideal for premium packaging solutions.
