Abstract
A pallet block includes an extruded inner core and an outer shell co-extruded with the inner core. The outer shell surrounds the inner core with respect to an extrusion axis defined by the inner core. The compositions of the inner core and outer shell differ by one or both of mass density and formula. For example, the outer shell may have a higher mass density than the inner core and may protect the inner core from impact and moisture ingression. Each of the inner core and outer shell may include product-packaging waste.

A pallet block comprising:
- an extruded inner core defining an extrusion axis, the inner core comprising a foamed composition of plastic and at least one of paper, wood, and metal;
- an outer shell co-extruded with the inner core, the outer shell surrounding the inner core with respect to the extrusion axis, the outer shell comprising plastic and at least one of paper, wood, and metal;
- wherein the mass density of the outer shell is greater than the mass density of the inner core.
A pallet comprising:
- at least one pallet member;
- a pallet block attached to the pallet member, the pallet bock comprising:
- an extruded inner core defining an extrusion axis, the inner core comprising a foamed composition of at least one of plastic, paper, wood, and metal;
- an outer shell co-extruded with the inner core, the outer shell surrounding the inner core with respect to the extrusion axis, the outer shell comprising plastic;
- wherein the mass density of the outer shell is greater than the mass density of the inner core.
