Abstract
A thermoplastic film which embodies a three-dimensional pattern. 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.
Claims13
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.
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.
