<p>PROBLEM TO BE SOLVED: To improve oilproofness and waterproofness while suppressing an amount of used additive for increasing oilproofness and waterproofness such as a fluororesin by using kenaf stalk pulp as a raw material for molding. SOLUTION: This container is integrally formed by molding with only kenaf stalk pulp used as material pulp. That is, a paper-making cup 11 having an appropriate capacity according to specifications for a product to be made is selected, and material liquid M mainly containing the kenaf stalk pulp as a raw material is thrown in. Then liquid component L is discharged by suction or the like from a liquid drawing hole 12a of a supporter 12 at a lower end of the paper-making cup 11. Thus pulp fiber 13 of the kenaf stalk pulp is left on a carrier net 13 for forming a web-like layer having a certain thickness. Thus a base material 2 of predetermined shape is formed on the carrier net 3. This base material 2 is sent to a drying process, and after it is dried, an appropriate external additive is applied. An additive such as a fluororesin may be internally added to the material liquid M.</p> |
