Recyclable, paper-based packaging structures and articles comprise extensible or semi-extensible paper layer with an anisotropy ratio in the range of 0.67 to 1.5 and a polymer extrusion coating layer. Methods for forming same are also provided. The structures and articles have a puncture resistance of 3 lbf or greater. Recyclable, paper-based packaging structures and articles and methods are formed using a polymer extrusion coating layer disposed on one side of an extensible or semi-extensible paper layer having an anisotropy ratio in the range of 0.67 to 1.5. A second polymer extrusion coating layer is disposed on a second side of the paper substrate layer. Advantageously, the paper substrates have a puncture resistance in the range of 3 lbf to 13.5 lbf.
