The road to green printing needs "you and me"

How many laps can I make around the globe with a 1.3 billion meter beverage label ? "33 laps!" Hangzhou Songyu The employees of Printing and Packaging Co., Ltd. (hereinafter referred to as “Hangzhou Songyu”) will give an accurate answer. The label printing company that has just been established for three years is the winner of the 2014 "Sun Cup" Asian Label Award (hereinafter referred to as "Sun Cup") Food and Beverage Silver Award. What efforts have been made to achieve such amazing results in just three years? Let's listen to the story behind Hangzhou Songyu.

Come into being, strive to be a green print practitioner

Since 2010, the annual output of China's beverage industry has basically maintained a double-digit growth, with an average annual output of nearly 30 million tons. With the rapid development of the beverage market, the competition among major beverage brands has become increasingly fierce. Beverage brands not only pay attention to the taste and quality of products, but also pay more attention to the packaging of products. Therefore, the demand and quality of beverage labels are also increasing year by year. Increment. Under such an industry market development situation, Hangzhou Songyu came into being.

At the beginning of the business, Hangzhou Songyu was concerned that the printing industry was one of the industries that started to implement green environmental standards earlier. Since the printing industry officially promoted the implementation of green printing in 2010, green printing has achieved remarkable results in China. With lithography and commerce The green standards for bill printing and gravure printing have been introduced one after another. Hundreds of companies have passed the green certification, and the green printing campaign is in full swing. It is precisely because of the keen insight into such an era background and industry environment that Hangzhou Songyu has been adhering to the concept of green printing since its establishment and is firmly committed to being a practitioner of green printing.

Workers must first sharpen their tools

To make a good green label product, you have to work hard on the process. To this end, Hangzhou Songyu has established a green printing laboratory to conduct special research. As we all know, although the effect of gravure printing is very good, the traditional gravure printing is very serious. Therefore, how to improve the green index and environmental protection coefficient of gravure under the premise of ensuring beautiful visual effects has become a new topic for Songyu people to explore. Repeated experiments and research, Hangzhou Songyu has established a green gravure printing system from substrate, ink to energy consumption.

1. Replacement of printing materials

In terms of printing materials, PET is one of the substrates for label printing. Compared with traditional PVC materials, PET has advantages such as non-toxicity and good weather resistance, and it is ideal for producing only water and carbon dioxide after combustion. Environmentally friendly materials. Hangzhou Songyu actively promotes the transition from PVC to PET and strives to move toward a higher green environmental protection goal.

2. Ink update

In inks, inks commonly used in conventional gravure contain harmful substances such as benzene, xylene, and ketones. Sometimes, ketone-containing solvents are added due to process requirements, so there will be a large amount of benzene residues in the printed matter, and will be in the air. A large amount of VOC is emitted. In order to solve this problem, Hangzhou Songyu innovatively uses benzene-free ketone-free gravure inks and low-toxic esters to reduce pollution from the source.

3. Exhaust gas treatment

In the final exhaust gas treatment stage, Hangzhou Songyu has adopted a series of measures such as pretreatment, adsorption, and desorption catalytic combustion to make the exhaust emission strictly meet the national emission standards.

4. Exchange learning

In addition, as a new force in the label printing industry, Hangzhou Songyu has been actively communicating with its peers. The company not only actively participates in various industry activities, but also continuously strengthens exchanges and learning with various professional colleges such as Beijing Printing College, thereby continuously improving its own level. .

"In fact, the process of preparing the "Sun Cup" entries is also the process of upgrading our company's craftsmanship. We have learned a lot from it. The final prize is a kind of affirmation and encouragement for us. We will continue to work hard!" The voice of Hangzhou Songyu, I hope they can go further and further on the "green" road.

The topic of "environmental protection" in the two sessions went up again. Premier Li Keqiang pointed out that "it is necessary to lay a solid battle for energy conservation, emission reduction and environmental management. Environmental pollution is the cause of people's livelihood and the pain of the people. It must be controlled by iron fists. This year, carbon dioxide emissions. To reduce by more than 3.1%, chemical oxygen demand and ammonia nitrogen emissions should be reduced by about 2%, and sulfur dioxide and nitrogen oxide emissions should be reduced by about 3% and 5% respectively."

These figures require the efforts of each of our compatriots to let us act and become the practitioners of green printing.
