Abstract: Each of side grippers that function as a film gripper includes upper and lower openable clampers. These clampers are designed to hold an edge portion of a film, and are opened after film packaging is completed. At least one film contact member, out of two film contact members that are attached individually to the upper and lower clampers, is formed of a cowhide, a material having a property such that a frictional force between the contact member and the film increases to and stays at a certain level as the humidity around the film rises. With use of the film contact member made of the hide, the film gripping force can be restrained from decreasing and the film-releasability can be improved despite the increase of the humidity.
