<p><P>PROBLEM TO BE SOLVED: To provide a fluted container having excellent shape retention that could not attained in a conventional polyethylene terephthalate resin film, a polypropylene resin film, and a laminate formed from such a resin film and paper, and having excellent strength, rigidity, tear resistance, piercing strength, and moisture-proof property. <P>SOLUTION: The fluted container uses a film made from a resin comprising butylene terephthalate as its main constituent. In particular, the film has an intrinsic viscosity of 0.8 to 1.8dL/g, is an unstretched film, has a film thickness of 10 to 500μm, and contains silica particles, thereby making the shape retention more excellent. Excellent strength, rigidity, tear resistance, piercing strength, and moisture-proof property can also be attained. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
