Abstract

Biolaminate composite assemblies are provided. Generally, the biolaminate composite assemblies may comprise one or more biolaminate layers and at least one biolaminate layer may comprise polylactic acid. In one embodiment, a biolaminate composite assembly is provided comprising one or more biolaminate layers wherein the biolaminate composite assembly is three-dimensionally formable over a rigid non-plastic substrate. At least one of the biolaminate layers comprises polylactic acid and a natural wax. In another embodiment, a method for forming a biolaminate composite assembly is provided.

Claims

1. A biolaminate composite assembly, consisting of:

a biolaminate layer comprising polylactic acid and soy wax;

a print layer;

a surface layer consisting of a UV cured coating and quartz mineral, wherein the surface is textured.

2. The biolaminate composite assembly of claim 1, wherein the soy wax is present at about 5% by weight of the biolaminate composite assembly.

3. The biolaminate composite assembly of claim 1, wherein the biolaminate layer comprises over 50% polylactic acid by weight with respect to the total weight of the biolaminate layer.

4. A biolaminate composite assembly, consisting of:

a biolaminate layer having polylactic acid, soy wax, and a filler; and

a surface wear layer, consisting of a UV cured coating and quartz mineral.

5. The biolaminate composite assembly of claim 4, wherein the filler is a colorant.

6. The biolaminate composite assembly of claim 4, wherein the biolaminate composite assembly is three-dimensionally formable over a rigid non-plastic substrate.

7. A biolaminate composite assembly consisting of:

a biolaminate layer having polylactic acid and soy wax;

a print layer;

a surface layer consisting of a UV cured coating and quartz mineral; and

paper adhered to the biolaminate layer.

8. A biolaminate composite assembly consisting of:

a biolaminate layer having polylactic acid and soy wax;

a print layer; and

a surface layer consisting of a UV cured coating material and quartz mineral, wherein the surface layer is of textured, and wherein the biolaminate is formaldehyde free.
