About 70% of Dongjiu’s papers are for green, eco-friendly use. Its sample design papers are classified into two types. One is for book papers. It uses different white quality paper with similar effect images printed on different texture of the paper so that users easily identify the differences of the paper quality. The other is for packaging papers. Dongjiu uses a three-dimensional folding effect and laser technology to create a sense of emotion towards the papers and create a clear expression of the paper characteristics.
