The thermoplastic film comprises a three-dimensional pattern including at least three sub-patterns of deformations. The shape, positioning, and pattern deformation density of the at least three sub-patterns of deformations cause the three-dimensional pattern to give the thermoplastic film a thicker appearance. ## Claims ### Claim 1 A thermoplastic bag with one or more patterns formed by post-formation deformation, the thermoplastic bag comprising: a first plurality of deformations in a first pattern; a second plurality of deformations in a second pattern; a third plurality of deformations in a third pattern; and a fourth plurality of deformations in a fourth pattern, wherein the first pattern is concentric to the second pattern, the second pattern is concentric to the third pattern, and the third pattern is concentric to the fourth pattern, wherein the first plurality of deformations in the first pattern is a first number of nesting squares at a first distance from each other, the second plurality of deformations in the second pattern is a second number of nesting squares at a second distance from each other, the third plurality of deformations in the third pattern is a third number of nesting squares at a third distance from each other, and the fourth pattern is a single square, and wherein the first pattern, the second pattern, and the third pattern provide a three-dimensional appearance to the thermoplastic bag. ### Claim 2 (depends on 1) The thermoplastic bag of claim 1, wherein: the first plurality is more than the second plurality; and the second plurality is more than the third plurality. ### Claim 3 (depends on 1) The thermoplastic bag of claim 1, wherein: the first pattern comprises a first pattern deformation density; the second pattern comprises a second pattern deformation density;

the second pattern comprises deformations having a second height; and the third pattern comprises deformations having a third height. ### Claim 7 (depends on 1) The thermoplastic bag of claim 1, wherein the first pattern is a first shape, the second pattern is a second shape, and the third pattern is a third shape. ### Claim 8 (depends on 1) The thermoplastic bag of claim 1, wherein the first pattern, the second pattern, and the third pattern form a repeat unit. ### Claim 9 (depends on 8) The thermoplastic bag of claim 8, wherein the repeat unit comprises at least one of a polygon, a parabola, a circle, or a non-symmetric complex geometric shape. ### Claim 10 A thermoplastic bag with one or more patterns formed by post-formation deformation, the thermoplastic bag comprising: a first sidewall and a second sidewall joined together along a first side edge, a second side edge, and a bottom edge; an opening opposite the bottom edge; a first plurality of deformations in a first pattern formed in the first and second sidewalls; a second plurality of deformations in a second pattern formed in the first and second sidewalls; a third plurality of deformations in a third pattern formed in the first and second sidewalls; and a fourth plurality of deformations in a fourth pattern, wherein the first pattern is concentric to the second pattern, the second pattern is concentric to the third pattern, and the third pattern is concentric to the fourth pattern, wherein the first plurality of deformations in the first pattern is a first number of nesting squares at a first distance from each other, the second plurality of deformations in the second pattern is a second number of nesting squares at a second distance from each other, the third plurality of deformations in the third pattern is a third number of nesting squares at a third distance from each other, and the fourth pattern is a single square, and wherein the first pattern, the second pattern, and the third pattern provide a three-dimensional appearance to the first and second sidewalls of the thermoplastic bag. ### Claim 11 (depends on 10) The thermoplastic bag of claim 10, wherein: the first plurality is more than the second plurality; and the second plurality is more than the third plurality. ### Claim 12 (depends on 11) The thermoplastic bag of claim 11, wherein: the first pattern comprises a first pattern deformation density; the second pattern comprises a second pattern deformation density; and the third pattern comprises a third pattern deformation density. ### Claim 13 (depends on 10) The thermoplastic bag of claim 10, wherein: the first pattern comprises deformations having a first height; the second pattern comprises deformations having a second height, and the third pattern comprises deformations having a third height.
