There are many varieties of paper bags, various kinds of paper materials, and many styles.
According to the material, it can be divided into: white cardboard paper bag, white paper paper bag, copper paper bag, kraft paper bag, and a small amount is made of special paper.
As we all know, 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.
Second, not environmentally friendly
Not all paper bags are degradable, and some paper bags are pressed with plastic film. If the film material is PVC, it will not only harm human health but also affect the normal decomposition of the paper material. In addition, the production of paper is still the use of logs as the main material, excessive production of paper bags, resulting in large-scale felling of trees, will also damage the environment. The immature papermaking technology produces a large amount of waste water and waste gas in the production process. If the processing equipment is backward, it will cause untreated or incomplete treatment, and it can still pollute the environment.
