Introduction to Printing and Lamination         The film covering effect is not only related to the film covering raw materials and film covering operation methods, but also related to the ink layer condition of the pasted printed matter. The condition of ink layer of printed matter is mainly determined by the nature of paper, ink performance, ink layer thickness, graphic area and integrated density of printed graphic.Introduction to Printing and Lamination         These factors affect the formation conditions of bonding mechanical adhesion and physical-chemical adhesion, resulting in the change of surface adhesion of printed matter.Introduction to Printing and Lamination         Ink layer thickness of printed matter. Field printed matter with thick ink layer is often difficult to bond with plastic film, and will soon delamination and blister. Introduction to Printing and Lamination       This is because the thick ink layer changes the porou […]

Pollution Problems and Countermeasures of Packaging and Printing        Today’s society has developed to the extent that all commodities need packaging and all packaging needs printing. Printing is the most important decoration and processing means of product packaging. Packaging without printing is almost unimaginable.Pollution Problems and Countermeasures of Packaging and Printing          Printing plays the role of transmitting information, publicizing and introducing products. At the same time, for some commodities, printing also plays an important role in anti-counterfeiting. Today’s packaging and printing is developing towards more exquisite and increasing the added value of goods.Pollution Problems and Countermeasures of Packaging and Printing        In all links of the printing process, such as he zushun, Hu Weiping, Tan Yiguo, School of mechanical and electrical engineering, Kunming University of tech […]

Modern Certificate Making Technology           In the application industry of packaging and printing, card materials are mainly plastics, including PVC, polyester, ABS plastics, etc. their performance is different from that of conventional similar materials.Modern Certificate Making Technology         For example, in order to prevent non-destructive stripping after hot pressing, the certificate substrate is required to have wrinkle resistance and tear resistance, while most of the conventional PVC is transparent, and it must have high light blocking performance for certificate preparation.Modern Certificate Making Technology   For example, copying watermark, adding security line, mixing special components, micro printing, broken line wiring, invisible pattern, setting secret mark, magnetic and color changing ink, unconventional signs (such as hologram, cursor image), IC chip, etc.Modern Certificate Making Technology     & […]

Environmental Harm of Printing Ink and Development of Environmental Protection Ink       With the increasing voice of environmental protection, as the main part of green printing, the requirements for environmental protection of ink are also increasing. It can be said that environmental protection ink is the first consideration for the development of ink in the future.Environmental Harm of Printing Ink and Development of Environmental Protection Ink   One Harm of ink to environment       Ink is the largest pollution source in the printing industry, and the annual output of ink in the world has reached 3 million tons. Global Organic volatiles caused by ink every year (VOC) pollution emissions have reached hundreds of thousands of tons. Environmental Harm of Printing Ink and Development of Environmental Protection Ink        These organic volatiles can form a more serious greenhouse effect than carbon dioxide, and will form oxides and photochemical […]
