Title: Water-soluble film
Inventor: MIYAZAKI HIROTOSHI
IPC: C08F16/02
Filed: 1988-09-12
Abstract: PURPOSE:To obtain a water-soluble film excellent in cold water solubility and alkali resistance by using a polyvinyl alcohol having a degree of saponification in a specified range and obtained by saponifying a polyvinyl ester with an acid as a component. CONSTITUTION:This water-soluble film is prepared from a polyvinyl alcohol having a degree of saponification of 50-90mol% and obtained by saponifying a polyvinyl ester with an acid. When the above degree of saponification is excessively low, it tends to cause insufficient film strengths or a decreased water solubility, undersirably. When this degree is excessively high, it tends to cause insufficient initial water solubility, hardening of film or decreased melt moldability, undersirably. Especially, when it is excessively high, there is a disadvantage that the excellent features otherwise brought about by acid saponification cannot be realized. The degree of polymerization of the polyvinyl alcohol used is desirably 100-4000. When this degree is excessively low, the strength of the obtained film is low undersirably, and when it is excessively high, the processability in film formation is poor, undersirably.
