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. Wherein the one or more visually-distinct contact areas, cause the first film to take on the second appearance of the second film. The visually-distinct contact areas being of a uniform gauge and configured to separate before either of the first film or the second film fails when subjected to peel forces.
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 areas where the first thermoplastic film and the second thermoplastic film are unbonded;
- and
- a plurality of contact areas between the first thermoplastic film to the second thermoplastic film,
- wherein:
- contact areas of the plurality of contact areas, when viewed from an outside of the first thermoplastic film of the multi-film thermoplastic bag, have the second appearance,
- the contact areas of the plurality of contact areas are configured to separate before either of the first thermoplastic film or the second thermoplastic film fails when subjected to peel forces, and
- a respective gauge of the first and second thermoplastic films in the one or more separated areas between adjacent contact areas of the plurality of contact areas is substantially uniform and has a same respective gauge as the first and second thermoplastic films in the adjacent contact areas.
A multi-layer thermoplastic bag comprising:
- a first thermoplastic bag comprising first and second opposing sidewalls joined together along a first side edge, an opposite second side edge, and a closed bottom edge, the first thermoplastic bag being pigmented with a first color or unpigmented;
- a second thermoplastic bag positioned within the first thermoplastic bag, the second thermoplastic bag comprising third and fourth opposing sidewalls joined together along a first side edge, an opposite second side edge, and a closed bottom edge, the second thermoplastic bag being pigmented with a second color;
- and
- at least two visually-distinct contact areas between the first thermoplastic bag to the second thermoplastic bag,
- wherein:
- the at least two visually-distinct contact areas, when viewed from an outside of the first thermoplastic bag, has the second color,
- the at least two visually-distinct contact areas are configured to separate before either of the first thermoplastic bag or the second thermoplastic bag fails when subjected to peel forces,
- the first and second thermoplastic bags in one or more separated areas between the at least two visually-distinct contact areas each have a substantially uniform gauge that is the same in portions of the first and second thermoplastic in the at least two visually-distinct contact areas, and
- the at least two visually-distinct contact areas are not deformed out of plane.
