aluminium foil, which is different from the general printing paper, with thenon absorbable property,iIt has poor affinity to ink in printing and can not achieve normal ink transfer,therefore, surface treatment must be carried out. The surface treatment before aluminium foil printing is mainly pre coating. In addition to improving the transfer capability of the ink, the pre coating also has the ability to increase the corrosion resistance. According to the requirements, the pre coating before the aluminium foil printing can be similar to the aluminium foil coloring process, and the aluminium foil coating process can also be used.
aluminium foil printing products are mainly used for flexible packaging materials. According to specific conditions, the basic characteristics of printing ink are shown in table A below:
The main components of aluminium foil printing ink are pigments, resins and volatile organic solvents. The nature of the pigment determines the color of the ink, the coloring force and the acid resistance, alkali resistance, water resistance and light resistance, as well as the drying, covering and density of the ink,etc.
A: characteristics of printing ink for soft packaging materials
| characteristics of printing ink | Main contents and basic requirements |
| Light resistance | It does not produce discoloration and colour fading under light irradiation |
| Friction resistance | Ink can not fall off when friction |
| Folding resistance | After printing, there is no big bending in processing and packaging |
| Sticky page resistance | In the crimp state, the printing surface can not produce sticky pages with other surfaces. |
| Luster | To enhance the value of packaged goods, the printing surface should be glossy. |
| No bad odor | The solvent can't leave a bad odor on the film |
| Health safety | Ink can't harm the health of the human body |
| Solvent resistance | Compound processing has certain adaptability to solvents in adhesives |
| Drug-resistant character | Anti acid, anti alkaline |
| Oil resistance | Oil resistance to oily food |
| Heat resistance | Heat resistance in post processing (composite, bag making, packaging) |
| Water resistance | After printing, the ink layer can not be stripped from water |
| Boiling resistance | Have this requirement for steamed goods |
| Freeze resistance | The performance of refrigerated goods in cold places |
| Gas resistance | Performance of packaging materials using gas heating sterilization |
| Radiation-resistant linearity | The properties of packaging materials for radiation sterilization |
