Zusammenfassung:This invention relates to a degradable container, especially a disposable degradable container for containing food or beverages. This invention also relates to a method of producing such a container. A degradable container is disclosed as containing 60 wt % to 70 wt % of a plant fiber, from 10 wt % to 30 wt % of an adhesive and from 0.1 wt % to 5 wt % of a demoulding agent, in which the adhesive is a modified urea-formaldehyde resin. A method of forming a degradable container is also disclosed as including the steps of (a) grinding a plant fiber to a size smaller than a pre-determined size; (b) nixing grounded plant fiber obtained under step (a) with a demoulding agent to form a premixed material; (c) mixing said premixed material with an adhesive into a powder form; (d) press-moulding said powder obtained under step (c) a first time under a pressure of 5-80 MPa; and (e) press-moulding said powder a second time under a pressure of 1.5-16 MPa into said container.
