As we all know, paper is a recyclable resource. 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 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. The raw material used is petroleum, and petroleum is already our scarce energy source. In contrast, the raw material for the production of paper bags is trees, which is a renewable resource. It is naturally degradable and recyclable, and has been given a green label.
Not environmentally friendly
Not all paper bags are degradable. Some paper bags are pressed with plastic film. If the film material is polyvinyl chloride, it will not only harm human health, but also affect the normal decomposition of the paper material. In addition, the production of paper still uses logs as the main material, and excessive production of paper bags has led to a large number of felling of trees, which will also damage the environment. The immaturity of papermaking technology has caused a large amount of waste water and waste gas to be produced during the production process. If the treatment equipment is backward, it will be discharged without treatment or incomplete treatment, which can still pollute the environment.
