Study on Life Cycle Inventory Analysis of Folding Carton

Abstract

To study the folding carton production process of an enterprise in the material consumption, energy consumption and environmental impacts which provides a reference for improving the production process of folding carton and reducing environmental pollution. Methods According to the input and output data of the folding carton production process, using the rebalance life cycle assessment software, the life cycle inventory of folding carton production process was analyzed by the method of life cycle assessment. Results In the production processes of folding carton, the greatest impact on the environment is silk screen, followed by offset printing. The power consumption of offset printing machine is large. At the same time, the ink amount of offset printing and silk screen is consumed greatly which causes serious environmental pollution. Conclusion The effect of the folding carton production process on the environment is mainly from silk screen and offset printing, and the production process of offset printing and silk screen needs to be improved.
