| titleOfInvention | Polyvinyl alcohol film roller |
| abstract | A roll obtained by winding a PVA film having a thickness of 45 [ mu ] m or less and a length of 2,000m or more, wherein the average interval between adjacent films is 5 [ mu ] m or less; and a method for producing a roll obtained by winding a PVA film having a thickness of 45 [ mu ] m or less and a length of 2,000m or more, wherein a contact winding method is adopted, the pressure between the film roll and the contact roll is 3 to 30N per 1m of the length of the film roll in the axial direction on average, and the winding speed is 30 m/min or less. Thus, a roll of a PVA film having a good appearance shape in which wrinkles and core displacement are less likely to occur even when the PVA film is thin and has a long winding length can be provided. |
