Abstract

PURPOSE: To improve cutting facility and solvent resistance of polyvinyl alcohol film by coating one side of the polyvinyl alcohol film as a backing with a pressure- sensitive adhesive having weak adhesive strength to thereby obtain a re-releasable adhesive sheet which protects a variety of articles against damage during storage, transportation and processing.
CONSTITUTION: A weakly adhesive pressure-sensitive adhesive is applied to one side of a backing which is a film having a thickness of 0.02W0.07mm, pref., 0.03W 0.06mm and prepared from a polyvinyl alcohol (saponified product having a saponification degree of at least 99.0%) containing 0W15wt%, pref., 1W10wt% of a plasticizer. When the plasticizer content exceeds 15wt%, the film becomes soft and, when carved or cut, does not give sharp and clear incision. The use of films having a tickness of below 0.2mm gives a disadvantage that the films are easy to crease when applied to articles to be protected and further the films are easily broken when released. The use of films having a tickness of more than 0.07mm gives a disadvantage that the adaptability of the adhesive sheet with articles to be protected becomes insufficient.
