There are plastic bags, which brings inconvenience to consumers; the proliferation of plastic bags hinders the purification of the environment.
Since the beginning of this year, stories about stone paper have been mentioned many times. Someone flushed the memo paper made of stone paper under the faucet and found that the stone paper was not soaked or leaked.
It didn't take long for a rag to wipe off the water on the paper, and the paper was basically restored to its original condition.
"This kind of paper does not contain plant fibers, so it is much better in terms of water resistance." Zhang Chongwu, CEO of the stone paper manufacturer and Earth Guardian, told reporters that paper bags made of stone paper feel heavier and cooler than ordinary paper bags. The thing is, it is very strong. They once tried to pour water into a handbag made of stone paper, and the result was that the handbag filled with 20 kg of water was intact and there was no leakage.
According to reports, the traditional papermaking process requires a large amount of wood to be cut as raw materials. And this kind of stone paper mainly extracts calcium carbonate in limestone, and then uses polymer as the base material, utilizes the interface chemistry principle of polymer and the characteristics of polymer modification, and is processed by special technology. Manufactured by extrusion and blow molding process.
The production of stone paper does not need to cut down wood. In addition, there is no need to add a large amount of strong acid, alkali, bleach and other chemicals in the production process, and no waste water, waste residue, toxic and harmful gases and substances are discharged.
