Composite packaging film printing material affects the quality of packaging.stand up spout pouch manufacturers

　　In the soft packaging industry, the composite packaging membrane has good flexibility, moisture -proof, oxygen, shielding, water resistance, anti -static, can be pumped, can be used, and can greatly improve the comprehensive performance of the packaging finished product.

　　The printing process is very important in the production of composite packaging membranes. Printing of packaging products is a manifestation of corporate marketing methods. It can be used to improve the popularity of enterprises. The unclear printing and text in actual production is a common printing problem for composite packaging membranes. one.

　　When printing the composite packaging membrane, materials that affect the quality of printing include printed materials, printing ink, solvents and rubber rollers. The printed material when printed by the composite packaging film refers to plastic, paper, aluminum -plated paper and aluminum foil. During printing, if the surface of the aluminum foil is not properly treated, excessive oil will cause the ink to change the performance worse, which makes the printing graphic unclear. The aluminum -plated aluminum -plated aluminum plating is not good. The surface is uneven, and the printing finished products will produce a lot of highlights, resulting in unclear graphics and text.

　　Any item in the viscosity, fineness, tactitivity, liquidity, and adhesion of printing ink does not meet the printing requirements in the quality indicators, which will affect the transfer of inks on the printed material, resulting in the unclear graphic printing and text of the print. In addition, excessive impurities in the ink will also affect the definition of prints and texts. Therefore, when the old ink is on the machine, it should be filtered, and a certain amount of new ink should be added. If necessary, you can use the new ink.

　　In addition, pay attention to the purity of the solvent when printing the composite packaging film. Once the purity is low, and contains too much fat or water, it will not be conducive to the dissolution of the ink, which will cause the printing graphics to be unclear and unique; How much, the shape and depth of the net acupoint, the quality of the chrome layer, and the advantages and disadvantages of surface polishing treatment. When the composite packaging membrane concave printing will directly affect the transfer rate of ink in the network acupoint. The ink transfer rate is low, and the printing graphic is not clear. , Not full.
