New technology, the catalyst for soft packaging enterprises to take off (I)

in today's increasingly standardized soft packaging enterprises, the importance of new technologies and processes to the development of soft packaging industry is increasingly highlighted. Using new technology to replace traditional technology or manual mechanical operation can not only improve production efficiency, save labor cost, but also facilitate management. "2005 International Soft Packaging Exhibition" is about to be held. What new technologies that will affect the development of the industry will appear at this exhibition, which has attracted wide attention in the industry

application of ink in heat transfer process

heat transfer

heat transfer process has been widely used in recent years. The process is mainly to soften the ink by heating, and then transfer the printed pattern or text to the transferred material by pressure. It has the advantages of good adhesion, bright and three-dimensional printing patterns, and unrestricted transfer forms. It relies more on human capital, quality and technological progress

the heat transfer film commonly used in high-tech fields such as military industry, aerospace, electronics, etc. is made of pet untreated film (thickness 12 μ- twenty μ) It is a printing substrate, coated with release agent, and then printed with ink to form a heat transfer film

normal> good heat transfer ink has low viscosity and high color concentration, and the ink fineness is 4 μ Below, the printing speed can reach M/min. when the required experimental force is reached, the servo motor stops rotating. At the same time, it must have good light resistance, heat resistance and environmental protection requirements

normal> the choice of ink depends on the different materials to be transferred. Generally, if the materials to be transferred are ABS, PVC, PU, etc., there is no need to apply back glue, and the ink can be directly transferred and attached to the materials. For metal materials, cloth, wood products, PE, PP, EVA and other materials, the back glue shall be coated after the ink layer, or the back glue shall be coated on the transferred material before heat transfer, so that the ink can be well attached to the material

normal> the aluminized film for thermal transfer printing is generally divided into full transfer and half transfer (Section Transfer). The full transfer aluminized film is required to have strong tensile force after transfer, while the half transfer aluminized film is emphasized on section. The process of aluminizing film is to aluminize after printing the coloring layer, and then select the back glue coating on the electroplating layer according to different transferred materials

normal> the ink characteristics of the transferred aluminized film are that it does not change color during Aluminizing and adheres well to the electroplated layer. The choice of adhesive backing varies with the material. A good adhesive backing must be able to effectively adhere to both the aluminum coating and the material

normal> general heat transfer process and ink selection are as follows:
