[0017]The following detailed description illustrates an embodiment of the present invention; however, it is not intended to limit the scope of the appended claims in any manner.

[0018]FIG. 1 shows one embodiment of the substrate suitable for use in the blister package of the present disclosure. The substrate (100) may include a paperboard layer (101) having a first surface (102) and a second surface (103), and a PLA layer (104) adhered to the first surface (102) of the paperboard layer (101). When desired, a layer of coating (105) may be applied to the second surface (103) of the paperboard (101) to enhance printability of text and / or graphics. The coating layer is selected based on compatibility with the printing method and the composition of paperboard. For example, the coating layer may include clay, titanium dioxide and / or calcium carbonate.

[0019]FIG. 2 shows another embodiment of the substrate suitable for use in the blister package of the present disclosure. The substrate (200)...
