The emergence of any new thing has two sides. The modern society advocates green environmental protection. Paper bag machine, paper bag appeared in this period has the corresponding environmental protection and not environmental protection contradictory characteristics
As we all know, paper is a recyclable resource. Papermaking raw materials are mainly plant fiber, raw materials contain cellulose, hemicellulose, lignin in addition to the three main components, there are other less content of components, such as resin, ash, etc. There are also auxiliary ingredients such as sodium sulfate. Paper in addition to plant fiber, but also need to add different filler according to different paper materials. The plastic bags commonly used are made from polyethylene using oil, which is already our scarce energy source. Paper bags, by contrast, are made from trees, a renewable resource. It is naturally labeled green for its characteristics of being degradable and recyclable.
Of course, not all paper bags can be degraded. 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 still uses logs as the main material. Excessive production of paper bags leads to a large number of trees being felled, which will also damage the environment. Papermaking technology is not mature, so that a lot of waste water and waste gas produced in the production process if the treatment equipment is backward, it will lead to untreated or incomplete treatment on the discharge, still can pollute the environment.

I believe that with the continuous development of high technology, the design of paper bags will be more integrated into the concept of environmental protection in the near future, and pay more attention to its economic applicability and green environmental protection.
