<p><P>PROBLEM TO BE SOLVED: To provide a composite container which has a barrier layer as the constituent layer, and does not generate the problem of an interlaminar peeling or the like over a long period of time even in the case that a content contains an alcohol component or a strong alkaline liquid. <P>SOLUTION: This composite container is a successively laminated body with a heat-sealing layer, a paper layer, the barrier layer, an anchor coating layer, and the heat-sealing layer. In this case, the composite container is formed by making the heat-sealing layer on the barrier layer side into an innermost layer. In the composite container, the anchor coating layer is an coating dry layer applied on the barrier layer surface of an aqueous dispersed body. In this case, the aqueous dispersed body consists of a polyolefin copolymeric resin particle which contains an unsaturated carboxylic acid or its anhydride in a range of 0.01 to 5 mass%, and also, of which the number-average particle size is 1μm or lower, and does not substantially contain a non-volatile auxiliary agent for aquatic transformation. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
