Zijiang Color Printing: Unswervingly escorting for green printing

To better promote green Printing concept, disseminate green printing knowledge , and guide green production. Xiaobian now conducts in-depth reports on the benchmark enterprises that implement green printing, and disseminates advanced experience, in order to jointly promote the green printing process in China. In this issue, let us join the first batch of enterprises in the country that pass the gravure green printing certification - Shanghai Zijiang Color Printing and Packaging Co., Ltd., to appreciate its green style.

Company Profile

Shanghai Zijiang Color Printing & Packaging Co., Ltd. (hereinafter referred to as “Zijiang Color Printing”) is located in Shanghai, an international metropolis. Packaging printing was encouraged as a metropolitan industry more than a decade ago, and Zijiang Color Printing has also achieved rapid development.

In May 2001, Zijiang Color Printing invested in a new modern factory. The entire plant has central air-conditioning, fire protection, environmental protection, warehousing and other systems, in line with international environmental, health and safety requirements. Since moving into the new factory, the control of emissions and environmental printing has become the consensus of the company's upper and lower levels. The green printing concept is deeply integrated into the company's “blood”. Providing socially responsible products and services has become one of the core parts of the company's culture.

From the perspective of Zijiang color printing, applying for gravure green printing certification is not only to meet the national and social requirements for environmental protection in the gravure industry, but more because of the company's own deep understanding of green printing.

Introducing green printing technology to escort green printing

As early as 2000, Zijiang Color Printing introduced solvent-free composite equipment and multi-layer co-extrusion blown film equipment; in 2006, it was the first in the industry to achieve benzene-free and ketone-free printing;

In 2008, the composite solvent recovery unit was put into use, and more than 70% of the composite solvent was recovered and reused.

In 2012, the original composite solvent recovery unit was completely updated. The original steam desorption was changed to nitrogen desorption. The advanced technology such as on-line detection and adsorption was used to increase the recovery rate of the composite solvent to over 90%, and the VOCs emission reached the standard. At the same time, the waste water generated by steam desorption is eliminated;

In 2014, printing solvent recovery was implemented to replace the original catalytic combustion unit.

The determination of the company's management is the key to implementing green printing

In the process of implementing green printing, the most important point is the determination of the company's management, that is, whether it can clearly recognize the necessity and urgency of insisting on the development of green printing, instead of using green printing only as the image project of the company.

Whether it is the introduction of new processes, new production lines, or the use of new materials and new systems, there will be some unexpected problems, and will also pay a lot of tuition. Without the determination and persistence of the company's management to implement green printing, it is hard to imagine that our company will continue to follow the green printing road.

For example, as the first company to introduce solvent-free composite equipment in China, in the initial stage of equipment introduction, the company faced difficulties in understanding the solvent-free production process, limited selection of solvent-free adhesives, lack of experience in solvent-free composite structures, and even caused A loss of hundreds of thousands of yuan.

In the end, with the support of the company's management and the efforts of the technicians, the company solved a series of technical problems and explored a complete set of solvent-free composite processes suitable for the company's actual situation, becoming the first company in China to master the solvent-free composite technology.
