Films and bags with visually distinct regions and methods of making the same

A multi-layer bag, 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 bonded with the second pigmented thermoplastic film layer;
• and
• a 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.

• a plurality of non-continuous bonds securing the first substantially un-pigmented thermoplastic film layer 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.
