摘要:Compositions, methods, and systems for manufacturing articles, particularlycontainers and packaging materials, having a fiber-reinforced, starch-bound cellularmatrix. Suitable mixtures used to form the articles are prepared by first preparing aviscous preblended mixture comprising water, a gelatinized starch-based binder, andfibers having an average length greater than about 2 mm. The highly viscous preblendedmixture effectively transfers the shearing forces of the mixer to the fibers. The finalmoldable mixture is then prepared by mixing into the preblended mixture the remainingstarch-based binder, water, and other desired admixtures, e.g., mold-releasing agents,inorganic filler rheology-modifying agents, plasticizers, coating materials, anddispersants, in the correct proportions to form an article which has the desired
performance criteria. The moldable mixtures are heated between molds at an elevatedtemperature and pressure to produce form-stable articles having a desired shape and aselectively controlled foamed structural matrix. The articles may be manufactured tohave properties substantially similar to articles presently made from conventionalmaterials like paper, paperboard, polystyrene, plastic, or other organic-based materials
and have especial utility in the mass-production of containers, particularly food andbeverage containers.
