In recent years, China's food packaging industry has developed rapidly, and the consumption of ink printing has increased significantly.
With the continuous progress of China's industrialization in breadth and depth, various environmental and food safety problems have become prominent.The field of flexible packaging, especially as the food packaging industry involved in the estimated contact with food materials and products, has attracted social attention.Food safety accidents again and again touched people's sensitive nerve, in the food packaging food contact plastic products and printing ink glue drilling agent and other fields threw up a tide of banning benzene.Ecological environment protection is imperative, food quality and safety can not be ignored.
Waterborne polyurethane series printing inks can be widely used in China's flexible packaging printing ink market, the key depends on some characteristics of waterborne polyurethane resin itself.
Compatibility of waterborne polyurethane resin: with waterborne polyurethane resin as the core, different auxiliary resins can be compatible, such as polyketone resin, phenolic resin, chlorine vinegar, tree vinegar, etc., and then the waterborne polyurethane printing ink system can be adjusted to show different characteristics, so as to be suitable for different application needs.
The plasticity of waterborne polyurethane resin itself: waterborne polyurethane resin in the process of synthesis, according to the application of different raw materials to modify it, and then effectively guide the final product has the function that people need.
