As we all know, paper is a recyclable resource. The raw materials of papermaking are mainly plant fibers. Apart from cellulose, hemicellulose and lignin, there are other components with less content, such as resin, ash and so on. There are also auxiliary ingredients such as sodium sulfate. In addition to plant fiber, paper also needs different filler based on different paper materials. The usual plastic bags made from polyethylene are made from petroleum, which is already our scarce source of energy. In contrast, the raw materials for paper bags are trees, which are renewable resources. The characteristics of its own degradable and recyclable are naturally labelled with green.
