Environmental concept: green
As we all know, paper is a recyclable resource. The raw materials of papermaking are mainly plant fibers. In addition to the three main components of 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. In addition to plant fibers in paper, different fillers need to be added according to different paper materials. The commonly used plastic bags are made of polyethylene and the raw material used is petroleum, which is already our scarce energy source. In contrast, paper bags are produced from trees, a renewable resource. It has the characteristics of being degradable and recyclable, and it is naturally labeled with a green label.
