<p><P>PROBLEM TO BE SOLVED: To provide a drawing paper container, which is drawn from a cardboard base paper, whose surface is laminated with a thermoplastic resin layer, by only a drawing, causes no pinhole, break, crack, or the like on the surface thermoplastic resin layer during a deep draw molding, and has a superior formability. <P>SOLUTION: The drawing paper container is formed by drawing a blank 3, which includes the cardboard base paper 30, whose surface is laminated with the thermoplastic resin layer 32, and has radial folded lines formed on the corners of the blank 3. The thermoplastic resin layer 32 is a polypropylene resin layer blended with a block copolymer, and has a static friction coefficient and a dynamic friction coefficient of 0.05-0.3. An intermediate layer 34, which is a completely additive-free single site LLDPE showing a tensile break elongation of 600 to 1,000%, is formed between the cardboard base paper 30 and the thermoplastic resin layer 32. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
