Generally, it includes packaging materials and technical principles, packaging safety and environment, printing technology and principles. I only recommend Jiangnan University and Hunan University of Technology, and Jiangda is 2 1 1, which is very good. Although Hunan industry is not 2 1 1, its employment and specialty are good. Wuhan University 985, it is also very good to be admitted. Zhengzhou University, Jinan University, Southwest University and Guangxi University are 2 1 1. Xi University of Technology, Xi University of Technology, Henan University of Science and Technology, Qilu University of Technology, Nanlin University and Tianjin University of Science and Technology are all ok, right?
