Printing/coating with aluminum foil as the substrate is called aluminum foil printing. Printing can give aluminum foil a new binding design, stimulate consumers' desire to buy, and increase the sales value of products. Printed aluminum foil is widely used in decorative materials such as food, medicine, and cosmetic packaging. Different from general printing paper, aluminum foil is non-absorbable, and has poor affinity with ink during printing, and cannot realize normal ink transfer, so surface treatment is necessary. The surface treatment of aluminum foil before printing is mainly pre-coating. In addition to improving the ink transfer ability, the pre-coating also has the ability to improve corrosion resistance. According to requirements, the pre-coating before aluminum foil printing can be similar to the aluminum foil coloring process, or the aluminum foil coating process can be used. Aluminum foil printing products are mainly used for flexible packaging materials. According to the specific situation, the basic characteristics of the ink are shown in the following table A: The main components of aluminum foil ink are pigments, resins and volatile organic solvents. The nature of the pigment determines the color, tinting strength, acid, alkali, water, and light resistance of the ink, as well as the drying, covering, and density of the ink. A: Characteristics of ink for flexible packaging materials Characteristics of printing inkMain contents and basic requirements Light resistanceIt does not produce discoloration and colour fading under light irradiation Friction resistanceInk can not fall off when friction Folding resistanceAfter printing, there is no big bending in processing and packaging Sticky page resistanceIn the crimp state, the printing surface can not produce sticky pages with other surfaces. LusterTo enhance the value of packaged goods, the printing surface should be glossy. No bad odorThe solvent can't leave a bad odor on the film Health safetyInk can't harm the health of the human body Solvent resistanceCompound processing has certain adaptability to solvents in adhesives Drug-resistant characterAnti acid, anti alkaline Oil resistanceOil resistance to oily food Heat resistanceHeat resistance in post processing (composite, bag making, packaging) Water resistanceAfter printing, the ink layer can not be stripped from water Boiling resistanceHave this requirement for steamed goods Freeze resistanceThe performance of refrigerated goods in cold places Gas resistancePerformance of packaging materials using gas heating sterilization Radiation-resistant linearityThe properties of packaging materials for radiation sterilization Main alloy: 8011, 8006, 8079, 8021 etc. Main tempering: O, H14, H18, etc. Thickness: 0.006mm-0.20mm Printed aluminum foil product categories: flat foil, gold foil, single-sided gold foil, double-sided gold foil, single-color foil, multi-color foil, laser anti-counterfeiting foil, medical PVC hard film, easy-to-tear film soft double aluminum foil, tropical aluminum foil, medical PVC/PVDC/PE /PCDC high-barrier composite hard aluminum foil sheet, medical PVC/PE composite hard sheet, etc. Uses: decoration materials for medicine, food, cosmetics packaging, etc. Main products 鈼?Pharmaceutical PTP aluminum foil, capsule aluminum foil, Pharmaceutical PTP aluminum foil packaging is mainly used for blister packaging of tablets, capsules, pills, etc., and can also be used for blister packaging of food and health products.
