Recyclable Blister Pack and Process of Making

A multi-piece package comprising:

• a fibrous substrate comprising:
• a first region including a planar inner surface and an outer surface opposite the inner surface;
• a second region including a planar inner surface and an outer surface opposite the inner surface;
• and
• an opening passing through the second region;
• wherein the inner surfaces of the first region and the second region are unprinted;
• a coadhesive layer located on opposing portions of the inner surfaces of both the first and second regions of the fibrous substrate, wherein the coadhesive layer includes a uniform layer of coadhesive on the inner surface of the second region surrounding the opening;
• and
• a plastic layer including a central region configured to accept a product and a peripheral flange surrounding the central region;
• wherein the opposing portions of the inner surfaces of the first region and of the second region are brought together such that opposing portions of the coadhesive layer are sealed to each other;
• wherein the central region of the plastic layer extends out of the opening and past the outer surface of the second region, wherein the peripheral flange of the plastic layer is captured between the opposing portions of the coadhesive layer without the coadhesive adhering to the plastic layer.

A multi-piece package comprising:

• a fibrous substrate comprising:
• a first region including an outer perimeter, a planar inner surface and a planar outer surface opposite the inner surface, wherein the planar inner surface extends uninterrupted between opposing portions of the outer perimeter such that the planner inner surface is bounded by the outer perimeter of the first region;
• a second region including an outer perimeter, a planar inner surface and a planar outer surface opposite the inner surface;
• an opening passing through the second region, wherein the second region includes sealing area extending between the outer perimeter of the second region and the opening, the sealing area surrounding the opening, wherein a width of sealing area between the opening and outer perimeter of the second region is at least one inch;
• wherein the inner surfaces of the first region and the second region are unprinted;
• a coadhesive layer located on opposing portions of the inner surfaces of both the first and second regions of the fibrous substrate, wherein the portion of the coadhesive layer on the second region surrounds the opening on the inner surface of the second region, wherein the coadhesive is an aqueous material that is configured to dry as a coadhesive after application to the substrate;
• and
• a plastic layer including a central region configured to accept a product and a peripheral flange surrounding the central region, wherein the peripheral flange has a width that is less than the width of the sealing area;
• wherein the opposing portions of the inner surfaces of the first region and of the second region are brought together such that opposing portions of the coadhesive layer are sealed to each other;
• wherein the central region of the plastic layer extends out of the opening and past the outer surface of the second region, wherein the peripheral flange of the plastic layer is captured between the opposing portions of the coadhesive layer without the coadhesive adhering to the plastic layer.
