LIQUID BLEACHING AGENT IN MULTILAYERED CONTAINER

摘要

PURPOSE:To prevent a liquid bleaching agent from decomposing under serve conditions by filling it in a thermoformed multilayered container which is composed of an outer layer comprising a thermoplastic resin which contains pigments and an inner layer comprising a thermoplastic resin which does not contain any pigment. CONSTITUTION:A component (c) is obtained by blending 99.99-50wt.% thermoplastic resin (a) thermoformable under bottle thermoforming conditions (e.g. a low-density PE) with 0.01-50wt.% pigment (b) (e.g. titanium white). A laminated sheet is formed from the component (c) and the component (a) which does not contain the component (b). The sheet is thermoformed, for example, by blow molding to produce a thermoformed multilayered container which comprises an outer layer (A) composed of the component (c) and an inner layer (B) composed of the component (a) and wherein the thickness ratio of A to B is 99.99-50:0.01-50. The container is filled with a liquid bleaching agent which comprises an aqueous solution of a hypochlorite and hydrogen peroxide as a bleaching base.
