As we all know, paper is a recyclable resource. The raw materials for papermaking are mainly plant fibers. In addition to cellulose, hemicellulose and lignin, there are other components with less content, such as resin and ash. In addition, there are auxiliary ingredients such as sodium sulfate. Besides plant fiber, different fillers need to be added according to different paper materials. Commonly used plastic bags are made of polyethylene, and the raw material used is oil, which is already our scarce energy. In contrast, the raw materials of paper bags are trees, which are renewable resources. Because of its biodegradable and recyclable characteristics, it is naturally labeled as green.
