Abstract: The present invention is directed towards a paper-based composite packaging structure comprising a paper layer and a filler layer which may be laminated or otherwise adhered to the paper layer. In certain embodiments, the filler layer comprises a polymer or bio-based polymer. An optional barrier layer may be deposited on to one side of the paper layer or filler layer as desired to provide functional barrier characteristics. The composite paper-based film structure(s) may comprise additional layers such as one or more optional primer layers, adhesive layers, ink layers, and/or sealant layers that can be incorporated into the composite film structure as desired to enable the required functional characteristics of the composite film structure described herein. The paper-based composite packaging structure is substantially compostable and/or recyclable as both the paper and the bio-based polymer filler layers will break down under composting conditions and/or meet standardized recyclability requirements.

Abstract translation: 本发明涉及一种纸基复合包装结构，其包括可以层压或以其它方式粘附到纸层的纸层和填料层。 在某些实施方案中，填料层包含聚合物或基于生物的聚合物。 可选择的阻挡层可以根据需要沉积到纸层或填料层的一侧以提供功能性屏障特性。 复合纸基膜结构可以包括另外的层，例如一个或多个任选的底漆层，粘合剂层，油墨层和/或密封剂层，其可以根据需要结合到复合膜结构中以使所需的功能性 本文所述复合膜结构的特征。 基于纸的复合包装结构基本上可堆肥和/或可回收，因为纸和生物基聚合物填料层将在堆肥条件下分解和/或满足标准化的可回收性要求。
