Abstract:Liquid packaging board (LPB) is the top quality packaging board. In recent years, LPB has become an important liquid packaging with its low material cost, high profit margin and environmentally friendly properties. The demand of LPB is increasing rapidly. In China, LPB products mainly rely on importing from Europe or America because the limited production capacity. In this paper, the significance of developing LPB was described, and the development situation of LPB at home and abroad, the selection of pulp materials, the sizing process and internal bond strength of LPB were summarized.
