Environmental protection concept

Paper is a resource that can be recycled. The raw materials for 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 components such as sodium sulfate. In addition to plant fibers, paper also needs to add different fillers according to different paper materials. The commonly used plastic bags made of polyethylene are made from petroleum, and oil is already a scarce source of energy. In contrast, paper bags are made from trees and are a renewable resource. The inherently degradable, recyclable features are naturally labeled with green labels.
