PURPOSE:To provide a bag self-disintegrating to allow a liquid or powder to flow out therefrom as required by a method wherein the plastic resin sheet formed by using a self-collasible plastic is shaped into a bag and this bag is filled with a liquid or powder. CONSTITUTION:A self-disintegrating plastic may be classified generally into two kinds: one is the polyethylene which results from the polymerization of ethylene and carbon monoxide and disintegrated by being irradiated with ultraviolet rays and the other results from the resinification caused by adding to polyethylene the starch such as corn starch in an amount of a few percent and is used for the plastic decomposition by feeding microorganisms in the soil with such startch. The plastic resin sheet formed by using partly or wholly either or both of such two kinds of the self-disintegrating plastic is shaped into a bag and this bag is filled with a liquid or powder and adjusted, so that the liquid or powder is allowed to flow out from the bag upon the plastic self- disintegration.
