Pharma aluminum foil packaging aluminum foil A hot stamping material directly rolled into a sheet of metal aluminum, the hot stamping effect is similar to that of pure silver foil stamping, so it is also called fake silver foil.
Since aluminum has a soft texture and good ductility, it has a silvery white luster. If the calendered sheet is smashed on a offset paper with a material such as sodium silicate, a pharma aluminum foil sheet can be formed, and printing can be performed. However, the pharma aluminum foil itself is easily oxidized and the color is darkened, and friction, touch, and the like are discolored, so it is not suitable for hot stamping of a book cover that has been preserved for a long time.
Therefore, it can be said that the pharma aluminum foil is a packaging material which has various excellent properties and is relatively perfect, and has fully demonstrated its broad application prospect in many fields.
