New molded pulp and molded fiber interior package cushioning (IPC) structures (10, 47, 70, 85, 105, 125, 150, 170) provide cushioning to protect products in a package. The IPC structure (10) defines a product-receiving cavity (12), reinforcing structural ribs (15, 16, 18), crushable structural pods (22, 25, 28). The ribs are in the form of elongate hollow ridges and include intersecting ribs (16, 18) extending in orthogonal directions. The ribs are distributed around the cavity to absorb energy in response to mechanical shock to prevent damage or breakage to the product. Other IPC structures include rows of pods (20), fillets (30), podded ribs (26), anti-hinge ribs, stacking ribs (26), shelves (32, 34, 35), corner protectors, etc. |
