摘要

A laminate structure for use as a liner in food packaging. The laminate structure includes a paper substrate layer, a metalized oriented polypropylene (mOPP) layer, an extruded mineral oil barrier layer disposed between the paper substrate layer and the mOPP layer and an innermost polymer layer disposed opposite the mOPP layer from the extruded mineral oil barrier layer. The laminate structure is suitable for use as a liner inside an outer shell fabricated from pulp containing recycled materials as the liner includes a mineral oil barrier layer between the outer shell and the inside of the package.
