Abstract

A roll of a water-soluble PVA film which has no or little slackness or creasing; and a process for producing the roll. The roll is formed from a water-soluble polyvinyl alcohol film which dissolves in 20°C water with stirring. The film, when examined after a drying step, has a plasticizer content and water content of 1-30 wt.% and 1-10 wt.%, respectively, and gives a roll in which the proportion of the interstices between the film layers is 4-25%. In a subsequent winding step, this film is wound on a cylindrical core at a film winding tension of 5-40 kgf per meter of the width to form a roll. A film unwound from this roll has a total width of deformed parts extending in the width direction for the film of 10% or smaller based on the overall width of the film.
