Carton packaging and cardboard. Nanjing packaging manufacturers pointed out that carton packaging and cardboard are an ancient packaging material that remained dominant until the 1980s. China's carton packaging and cardboard account for 40-50% of the packaging materials, occupying the first place. Paper and cardboard for packaging materials in carton packaging and total paperboard production also account for 40-50%. With the development of carton packaging plants, there will be a big development in packaging carton paper and cardboard. This article will introduce you to the variety of printing materials. Now, hot stamping foil is mainly divided into two kinds of printing materials: hot foil and cold foil. Gold foil printing materials must have metallic luster, so most of them contain components such as coloring agents, and people pay more attention to whether they have some harmful substances. Since many environmental regulations stipulate that all kinds of harmful substances in printed materials cannot exceed the standard, there are many hot foil products in the market that meet the environmental protection requirements. In the future, printed materials will be developed in the direction of low VOC emissions, low heavy metal content, low energy consumption processing, recyclability, and environmental protection that does not harm human and environmental safety. At present, there are already hundreds of printing companies in the country that have carried out green certification. It is possible that after the number of printing companies that have passed the green certification, the state will issue regulations. Recently, developed countries have entered the era of product carbon footprint, and one day in China will be the same. Therefore, printing companies need to achieve energy conservation, environmental protection and emission reduction as soon as possible to enhance their own competitiveness. Printed materials are just a microcosm of Dow's innovation in the flexible packaging industry. In addition, Dow can provide customers with the best combination of performance according to different performance needs and different prices. Among them, based on breakthrough patented molecular catalyst technology and advanced polymerization technology.
