TUBULAR PAPER CONTAINER

PROBLEM TO BE SOLVED: To provide a tubular paper container which maintains a high barrier characteristic and preserves a content for a long time. SOLUTION: This tubular paper container is provided by superimposing one end edge of a laminated material provided with at least a thermoplastic resin layer on its innermost layer and outermost layer, on the other end edge to form a body member whose top and bottom are open and sides are bonded to each other, one side of the body member is protected with an edge protect tape and the top and the bottom of the member are closed with a bottom member and a lid member. The tape 20 is constituted by laminating a first heat sealing thermoplastic resin 21, an inorganic chemical deposition film 22, a barrier film 23, and a second heat sealing thermoplastic resin 24 in the order. The resin 21 and the resin 24 of the tape are thicker than the resin 12 of the laminated material 10 forming the body part of the container. COPYRIGHT: (C)2009,JPO&INPIT
