six-color gravure printing press and other production facil-ities.The gravure printing plant, located on the headquar-ter, handles package printing and bag-making. We have a six-color and a two-color gravure printing presses, and bag-making machines. Substrates are mainly PE (HDPE and LDPE), PP, and PA, and the two-color press has a print-ing width of 700 mm, the six-color press has the printing width of 650 mm, and the printing pitch is 10 to 900 mm for the two-color press and 10 to 800 mm for the six-color press. In the case of contract processing, we use substrates the customer supplied by and provide our own inks. Some processing is done af-ter printing and bag-making, while others are done with just bag-making,” explains Mr. Youji Kita, who manages the printing and bag-making plant.In addition, Mr. Kita describes the characteristics of Godo Kasei as follows.The base material for printing and bag-making is a tube rolled up as an inflation film. Therefore, we have to print and make bags with two layers of film overlapping each other. Depending on the thickness of the film and the degree of uneven thickness, lateral shift and meandering are com-monplace, making processing extremely difficult. Also, depending on the season, PA and other films may absorb moisture, causing curling. Therefore, the printing speed is also slower than normal printing, running at about 50-60 m/min. As we have made improvements and reformed our A bag-making machine that doesn’t have side heating Inflation tube-shaped film is set at the unwinder of gra-vure printing pressSix-color gravure printing press used for 40 years. It was updated with servocontrol system but it is still required proficient skills to make precise printing registration.Gravure plate cylindersplates, so the machine length is short.Youji Kita36
