| titleOfInvention | Polyvinyl alcohol film roll |
| abstract | A roll formed by winding a PVA film having a thickness of 45 µm or less and a length of 2,000 m or more, wherein the average spacing between adjacent films is 5 µm or less; And, as a method of manufacturing a roll in which a PVA film having a thickness of 45 μm or less and a length of 2,000 m or more is wound, a touch winding method is employed, and the pressure between the film roll and the contact roll is 1 m in the axial direction of the film roll. Sugar is 3 to 30 N, and the winding speed is set to a manufacturing method of 30 m/min or less. Thereby, even if it is a case where a PVA film is thin and winding length is long, wrinkles and eccentricity do not generate|occur|produce easily, and the roll of a PVA film with a favorable external appearance is provided. |
