16. A method for forming a biolaminate structure, the method comprising:
-
providing a first paper layer; providing a biobased polymer film layer; providing a second paper layer; and at least partially saturating the first paper layer and the second paper layer with a biobased polymer, wherein saturation may be from the biobased polymer of the biobased polymer film layer or may be from an additional biobased polymer source; fusing the first paper layer, the biobased polymer film layer, and the second paper layer under means of heat and pressure to form the biolaminate structure. - View Dependent Claims (17, 18, 19, 20)
