4.The opinions and suggestions of packaging and printing professionals on how to develop the packaging and printing industry in the low-carbon era

Lin Huaxiang, Deputy General Manager of Guangzhou Tongze Machinery Co., Ltd.:

“Low-carbonization” should be a macro concept, directly related to energy conservation and emission reduction, and of course to flexible packaging. Low carbonization will inevitably lead to the packaging industry advocating energy conservation and emission reduction. In terms of the fields we serve, reducing energy consumption in the production process of flexible packaging (reducing energy consumption is also the main way to reduce emissions) is one aspect, reducing emissions into the air (mainly solvent emissions, which are not only harmful, but also solvents are petroleum products) , oil is an energy material) is one aspect. For example, in the production process of the flexible packaging process, replacing the dry composite process with a solvent-free composite process is an effective way to save energy and reduce emissions in the composite flexible packaging industry, and it is also the best choice! “Energy saving – no drying link is required (drying is the most serious power or energy consumption link in the composite process, accounting for more than 80% of the energy share in the composite process), emission reduction – no solvent is discharged into the air and other harmful substances” is one of the main features of the solvent-free composite process! It’s not advertising for ourselves, it’s the truth, telling the truth!

Ink expert Liu Jiaju:

With the introduction of global legislation on environmental protection and VOC emission control regulations, I believe that ink painting will achieve faster development, and enterprises should also focus more on ink painting. As an ink manufacturer, the production of water-based packaging and printing inks with low carbon emissions is not only conducive to the development of the enterprise, but also can take the initiative to assume the social responsibility of environmental protection, safety and pollution-free. With ink printing, 80% of the CO2 emissions produced come from the drying of the ink during the printing process. Because one kilowatt-hour of electricity in the power grid can cause about 500g of CO2 to be produced, that is to say, about 1.5t of CO2 is emitted per ton of ink produced until the terminal is used for printing. In terms of the overall emission ratio, the emission of ink is a low-carbon emission.
