    • Unexpectedly unique and environmentally friendly composite material structures, storage articles fabricated therefrom, and related methods. The composite structure includes at least one or more fiber-containing layers, such as fiberboard or other layers having fibers from natural and/or synthetic sources, and one or more mineral-containing layers. The mineral-containing layer(s) comprises a thermoplastic bonding agent fixing the mineral particles in place. The fiber-containing layer(s) and mineral-containing layer(s) can be shaped, sized, and manufactured such that the composite structure formed therefrom is capable of being machined to form the storage article. The composite structure can be repulped and recycled without the use of dispersions, emulsions, or aqueous solutions. Further, the composite reduces layer mass requirements for heat seal, barrier, and fiber adhesion compared to polymer layers. The composite structure further has tensile strength and other structural characteristics that allow it to be readily machined into desired storage article forms.
    • 意外的独特和环保的复合材料结构,由其制造的储存制品和相关方法。 复合结构包括至少一个或多个含纤维层,例如纤维板或具有天然和/或合成来源的纤维的其它层,以及一种或多种含矿物层。 含矿物层包括将矿物颗粒固定就位的热塑性粘合剂。 含有纤维的层和含矿物层可以成形,定尺寸和制造,使得由其形成的复合结构能够被加工以形成储存物品。 复合结构可以在不使用分散体,乳液或水溶液的情况下再浆化和再循环。 此外,与聚合物层相比,该复合物降低了热封,阻隔层和纤维粘合剂的层质量要求。 该复合结构进一步具有拉伸强度和其它结构特性,使其易于加工成所需的储存制品形式。
