Water-disintegrable resin film, laminated water-disintegrable resin film, water-disintegrable composite laminate and method for production thereof |
摘要 |
A water-disintegrable resin film, characterized in that it exhibits a tensile strength of 2 N/25 mm width or more after the surface thereof is pressed by a cotton gauze impregnated with water of 40° C. with a pressure of 1.47 N/cm<2 >for 5 hours under a condition wherein the temperature is 40° C. and the relative humidity is 90%, and exhibits a start time for the disintegration thereof by water, which means the time needed until it starts to lose its form, of 600 seconds or less, in a test nearly according to JIS P 4501 for the capability of being united. The water-disintegrable resin film has a predetermined mechanical strength under a wet and warm or hot condition and also exhibits excellent disintegradability for a large amount of water, and thus can be suitably used as a back sheet of a liner for sanitary goods, which requires the combination of good water resistance and good water-disintegradability.
