A compostable interior panel for use in a vehicle includes an injection molded compostable polymer. A layer is disposed about the compostable polymer and comprises a composting-resistant polymer having a thickness ranging from 10 μm to 175 μm. The compostable polymer and the composting-resistant polymer are substantially insoluble in one another when liquid.

1. A compostable interior panel for use in a vehicle, comprising: core comprising a compostable polyester composition capable of being a solid or a liquid; anda layer including a thermoplastic polymeric composition capable of being a liquid or a solid, the thermoplastic polymeric composition having a permeability to moisture ranging from 0.01 g·mil/100 in2·day to 0.5 g·mil/100 in2 day, when measured according to ASTM F1249, the layer having an exterior surface and an interior surface adjacent to the core, the layer being orientable and encapsulating the core when both compositions are solid, wherein the layer comprises a stretch melting flow front encapsulating the core when both compositions are liquids under pressure ranging from 750 lbf/in2 to 3000 lbf/in2, the layer, when solid, having a gradient of decreasing orientation from the exterior surface to the interior surface. 2. The compostable interior panel of claim 1, wherein the layer includes a polymer-clay nanocomposite. 3. The compostable interior panel of claim 1, wherein the compostable polyester comprises polylactic acid. 4. The compostable interior panel of claim 1, wherein the layer protects the core from composting. 5. The compostable interior panel of claim 1, wherein the thermoplastic polymer is a polyolefin. 6. The compostable panel of claim 1, wherein the thermoplastic polymeric composition has a number-averaged molecular weight ranging from 1000 to 150,000. 7. The compostable panel of claim 1, wherein the layer comprises a range from 0.1 wt. % to 5 wt. % of the core. 8. The compostable panel of claim 1, wherein the layer includes a first oriented microlayer having a first degree of biaxial orientation and a second oriented microlayer having a second degree of orientation and being disposed closer to the core than the first microlayer, the first degree of biaxial orientation being greater than the second degree of orientation. 9. The compostable panel of claim 1, wherein the panel is selected from a group consisting of a dashboard, an instrument panel, a glove box door cover, a console side, a pillow trim panel, a shelf, a trim cover, and an air handling vent. 10. The compostable panel of claim 1, wherein the layer is bonded to the core forming a laminated composite with a bond surface between the layer and the core, the bond surface having an area. 11. The compostable panel of claim 10, wherein the area of the bond surface is delaminated in less than 5% of the area. 12. A compostable interior panel for use in a vehicle, the panel comprising: a core including a bioplastic resin composition capable of being a solid or a liquid; anda layer including a plastic composition capable of being a solid or a liquid, the plastic composition having a permeability ranging from 0.05 g·mil/100 in2·day to 0.33 g·mil/100 in2·day, when measured according to ASTM F1249, the layer forming, when solid, a first microlayer having a first degree of orientation and a second microlayer having a second degree of orientation, the second microlayer being adjacent to the core, the first degree of orientation being greater than the second degree of orientation, the layer encapsulating the core and when both compositions are solids, the layer comprising a stretch melting flow front encapsulating the core, when both compositions are liquids under pressure. 13. The panel of claim 12, the resin composition is a compostable resin composition when measured according to ASTM D6400. 14. The panel of claim 13, wherein the compostable resin composition composts within one year when shredded. 15. The panel of claim 12, wherein the layer includes a nanocomposite. 16. The panel of claim 15, wherein the nanocomposite is polyolefin-clay nanocomposite. 17. A compostable interior panel for use in a vehicle, the panel comprising: a core including a compostable bioplastic resin composition capable of being a solid or a liquid; anda layer including a plastic composition capable of being a solid or a liquid and having a number-averaged molecular weight range from 1000 to 150,000, the layer encapsulating the core when both compositions are solids, the layer comprising a stretch melting flow front encapsulating the core, when both compositions are liquids under pressure ranging from 750 lbf/in2 to 3000 lbf/in2. 18. The panel of claim 17, wherein the resin has a first Hansen solubility parameter and the plastic composition has a second Hansen solubility parameter, wherein the difference between the first and second Hansen solubility parameters is greater than 2. 19. The panel of claim 17, wherein the layer further comprises a moisture permeation resistance additive. 20. The panel of claim 19, wherein the moisture permeation resistance additive is present in an amount ranging from 0.5 wt. % to 5 wt. % of the core.
