Abstract
One or more implementations of a multi-film thermoplastic structure include a first film having a first appearance in contact with a second film having a second appearance at one or more visually-distinct contact areas arranged into a text. Wherein the one or more visually-distinct contact areas, cause the first film to take on the second appearance of the second film. In one or more implementations the multi-film thermoplastic structure comprises a thermoplastic bag and text comprises a suffocation warning.
Claims20
A multi-film thermoplastic bag comprising:
- a first thermoplastic film having a first appearance;
- a second thermoplastic film having a second appearance created by a pigment, the first appearance differing from the second appearance;
- one or more separated portions where the first thermoplastic film and the second thermoplastic film are not in intimate contact, wherein the one or more separated portions are substantially flat;
- and
- one or more contact areas arranged to create text, wherein the one or more contact areas comprise:
- portions of the multi-film thermoplastic bag where the first thermoplastic film and the second thermoplastic film are in intimate contact;
- and
- a contrast relative to separated portions surrounding the one or more contact areas, which when viewed in the first thermoplastic film makes the text legible, wherein the contrast is due to a difference in Delta E between the one or more contact areas arranged to create text and the separated portions surrounding the one or more contact areas.
A thermoplastic bag comprising:
- a first thermoplastic film sidewall and a second thermoplastic film sidewall joined together along a first side edge, an opposite second side edge, and a closed bottom edge, wherein the first thermoplastic film sidewall and the second thermoplastic film sidewall comprise a first color;
- a layer of thermoplastic material adjacent to at least a portion of the first thermoplastic film sidewall, wherein the layer of thermoplastic material comprises a second color;
- one or more separated portions where the first thermoplastic film sidewall and the layer of thermoplastic material are separated by a gap, wherein the one or more separated portions are substantially flat;
- and
- one or more contact areas arranged to create text, wherein the one or more contact areas comprise:
- portions in which the first thermoplastic film sidewall and the layer of thermoplastic material are bonded together;
- and
- differ in appearance from separated portions surrounding the one or more contact areas making the text legible when viewed in the first thermoplastic film sidewall due to a difference in Delta E between the one or more contact areas arranged to create text and the one or more separated portions.
