Stone paper is a new type of material between paper and plastic. From the perspective of replacing the traditional part of paper, it can save a lot of forest resources for the society and reduce the secondary pollution generated in the papermaking process; from the perspective of replacing the traditional part of plastic packaging, it can save a lot of strategic resources for the country. . However, some experts questioned whether it can be truly degraded. As a new thing, stone-based paper is moving forward in controversy.
What is stone paper?
Stone paper is also called stone paper. It is mainly sourced from limestone mineral resources with large reserves and wide distribution (calcium carbonate content reaches 70~80%), and high-molecular polymers (content 20~30%) are used as auxiliary materials. The polymer interface chemistry and the characteristics of polymer modification are processed by a special process and made by polymer extrusion and blow molding processes. It is a variety of processed paper. Stone paper has the same writing performance and printing effect as plant fiber paper, and at the same time has the core performance of plastic packaging.
