The goal of this study is to compare the GSM deviation between the incoming Natural and Natural Special Poly rolls and the standard GSM values for the corresponding rolls. A thorough set of comparable data is gathered via literature and an industrial survey. With the aid of a certain set of tools, each individual roll of film was examined, and various readings were collected. These measurements were then analyzed to create the GSM deviation graph. According to this study, Natural Poly films displayed a lower GSM departure from the norm than Natural-special films.
