One or more implementations of a multi-layer film include a first substantially un-pigmented layer non-continuously bonded to a second pigmented layer. The multi-layer film includes an unexpected appearance differing from the appearance of the pigmented layer. In one or more embodiments, the multi-layer film includes a metallic appearance despite the pigmented layer being devoid of metallic pigment. The multi-layer film also includes areas that are visually distinct from areas of the film with the unexpected appearance. The visually-distinct areas comprise areas in which the first substantially un-pigmented layer non-continuously bonded is in intimate contact with the second pigmented layer. The visually-distinct areas have the appearance of the pigmented layer. One or more implementations also include methods of making multi-layer films and bags with an unexpected appearance and visually-distinct areas.

1. A multi-layer film, comprising: a first substantially un-pigmented thermoplastic film layer comprising a plurality of alternating stretched-thinner webs and thicker ribs, wherein the first substantially un-pigmented thermoplastic film layer is transparent or translucent;a second pigmented thermoplastic film layer comprising a pigment, the second pigmented thermoplastic film layer having a first color created by the pigment;a plurality of non-continuous bonds securing the first substantially un-pigmented thermoplastic film layer to the second pigmented thermoplastic film layer;un-bonded areas in which the first substantially un-pigmented thermoplastic film layer and the second pigmented thermoplastic film layer are un-bonded and in which there are no intervening layers between the first substantially un-pigmented thermoplastic film layer and the second pigmented thermoplastic film layer; andwherein, when viewed from the first substantially un-pigmented thermoplastic film layer side: the un-bonded areas have a second color differing from the first color, wherein the multi-layer film is devoid of a pigment of the second color; andone or more bonded areas have the first color. 2. The multi-layer film as recited in claim 1, wherein the one or more bonded areas comprise areas in which the first substantially un-pigmented thermoplastic film layer and the second pigmented thermoplastic film layer are in direct contact. 3. The multi-layer film as recited in claim 2, wherein the one or more bonded areas comprise areas in which the first substantially un-pigmented thermoplastic film layer and the second pigmented thermoplastic film layer are heat sealed together. 4. The multi-layer film as recited in claim 2, wherein the un-bonded areas having the second color comprise areas in which the first substantially un-pigmented thermoplastic film layer and the second pigmented thermoplastic film layer are separated by a gap. 5. The multi-layer film as recited in claim 4, wherein the first substantially un-pigmented thermoplastic film layer is transparent. 6. The multi-layer film as recited in claim 1, wherein: the first color is a non-metallic color; andthe second color is a metallic color. 7. The multi-layer film as recited in claim 6, wherein: the first color is carbon black;the second color is a metallic silver; andthe first substantially un-pigmented thermoplastic film layer is transparent. 8. A multi-layer film, comprising: a first substantially un-pigmented thermoplastic film layer, wherein the first substantially un-pigmented thermoplastic film layer is transparent or translucent;a second pigmented thermoplastic film layer comprising a pigment, the second pigmented thermoplastic film layer having a first color created by the pigment, wherein the second pigmented layer is directly adjacent to the first substantially un-pigmented thermoplastic film layer;a plurality of bonded areas in which the first substantially un-pigmented thermoplastic film layer is in intimate contact with the second pigmented thermoplastic film layer; anda plurality of un-bonded areas in which an air gap separates the first substantially un-pigmented thermoplastic film layer from the second pigmented thermoplastic film layer;wherein the un-bonded areas, when viewed from the first substantially un-pigmented thermoplastic film layer side of the multi-layer film, have a second color differing from the first color;wherein the bonded areas, when viewed from the first substantially un-pigmented thermoplastic film layer side of the multi-layer film, are the first color. 9. The multi-layer film as recited in claim 8, wherein the bonded areas comprise heat seals. 10. The multi-layer film as recited in claim 8, wherein the bonded areas comprise pressure bonds. 11. The multi-layer film as recited in claim 10, wherein the pressure bonds comprise embosses. 12. The multi-layer film as recited in claim 10, wherein the pressure bonds comprise ring rolled bonds. 13. The multi-layer film as recited in claim 8, wherein the bonded areas comprise lamination bonds. 14. The multi-layer film as recited in claim 8, wherein: the first color is a non-metallic color; andthe second color is a metallic color. 15. The multi-layer film as recited in claim 14, wherein: the first color is carbon black;the second color is a metallic silver; andthe first substantially un-pigmented thermoplastic film layer is transparent. 16. A multi-layer film, comprising: a first substantially un-pigmented thermoplastic film layer, wherein the first substantially un-pigmented thermoplastic film layer is transparent or translucent;a second pigmented thermoplastic film layer comprising a pigment, the second pigmented thermoplastic film layer having a first color created by the pigment, wherein the second pigmented layer is directly adjacent to the first substantially un-pigmented thermoplastic film layer;a plurality of non-continuous bonds securing the first substantially un-pigmented thermoplastic film layer in intimate contact to the second pigmented thermoplastic film layer;a plurality of heat seals securing the first substantially un-pigmented thermoplastic film layer to the second pigmented thermoplastic film layer;a plurality of un-bonded areas in which the first substantially un-pigmented thermoplastic film layer the second pigmented thermoplastic film layer are not bonded to each other;wherein the un-bonded areas, when viewed from the first substantially un-pigmented thermoplastic film layer side of the multi-layer film, have a second color differing from the first color;wherein the heat seals, when viewed from the first substantially un-pigmented thermoplastic film layer side of the multi-layer film, are the first color. 17. The multi-layer film as recited in claim 16, wherein the plurality of non-continuous bonds comprises pressure bonds. 18. The multi-layer film as recited in claim 17, wherein the pressure bonds comprise embosses. 19. The multi-layer film as recited in claim 18, wherein the pressure bonds comprise ring rolled bonds. 20. The multi-layer film as recited in claim 16, wherein the plurality of non-continuous bonds comprises lamination bonds. 21. The multi-layer film as recited in claim 16, wherein: the first color is carbon black;the second color is a metallic silver; andthe first substantially un-pigmented thermoplastic film layer is transparent.
