Source: Economic Daily Paper made of stone is not only environmentally friendly and durable, but its price is 1.5 to 2 lower than that of the same type of corrugated paper. In Shandong Xiangxian Hengsheng Paper Co., Ltd., the box made of stone paper has successfully captured many fresh-type manufacturers, and even Haier, Alibaba and other giant companies have expressed their intention to cooperate. Successfully captured many customers, Haier and Alibaba also expressed their intention to cooperate. In Shandong Xiangxian Hengsheng Paper Co., Ltd., general manager Yan Qiuling said that these boxes have a plastic feel when touched by hand, and the toughness is very strong, and it will not tear when pulled hard. Take it in your hand and feel softer than fiber paper products. In its production workshop, limestone with coal gangue and tailings slag as raw materials is crushed, screened and ground to form ultrafine modified ore powder, calcined into quicklime with calcium content of 57% or more; and then ground into nanometer super Finely add white stone powder, add 20% of specific PE, PP and other additives, and carry out special processing such as casting stretching and three-layer co-extrusion; finally, blow molding is formed into a carton. Yan Qiuling said: "The scientific name of this paper is 'environmental synthetic paper'. Its raw material is limestone. The content of stone in paper is 70% to 80%." The environmentally-friendly stone carton made of this paper has a particularly high compressive strength. It is resistant to folding, waterproof and integrated. It is reported that compared with ordinary corrugated cardboard, the burst strength of this paper is up to 264KPa, and the edge compressive strength is doubled. It will not be deformed and damaged in the environment of minus 40 degrees Celsius to minus 80 degrees Celsius, especially suitable for fruits. , transport packaging of vegetables, frozen seafood, etc. Yan Qiuling revealed that there are already many fresh-type manufacturers who have chosen stone cartons, and Haier and Alibaba have expressed their intention to cooperate. Environmentally friendly and durable, the price is lower than the same type of corrugated paper According to reports, the biggest feature of stone paper is environmental protection. Since the entire production process is a physical change, complete zero emissions are achieved. In terms of water use, traditional papermaking consumes 100 tons of fresh water per ton of paper produced, while the entire production process of the stone paper production process does not require water; In the raw materials, the main raw material of traditional papermaking is forest and grass resources, and the main raw materials of the stone paper production process are coal gangue, slag and other stone materials. The most important thing is that the product can be recycled indefinitely. After the used carton is recycled, it can be directly crushed and processed without causing secondary pollution. Yan Qiuling said that stone paper is not only non-flammable, but the only product produced after burning is white calcium carbonate powder, which can be used as a raw material. “In addition to environmental protection, its price is also 1.5 to 2 lower than the same type of corrugated paper.†A seemingly simple stone board production line is supported by three production technology invention patents and 14 new equipment patents. Yan Qiuling said: "At present, one production line consumes 15 tons of stone every day. There are many coal gangue and tailings slag in our county. Our goal is to 'eat dry and clean' these solid wastes, all made into recyclable 'green' stone paper.
