Abstract
A household appliance liner includes a first polymeric capping layer and a polymeric base layer. The first polymeric capping layer includes a first pigment additive. The polymeric base layer is coupled to the first polymeric capping layer. The polymeric base layer includes one or more polymers, a second pigment additive, and a natural fiber. The natural fiber can be present at a concentration of at least 50% by weight of the polymeric base layer. Methods of producing the household appliance liner are also disclosed.
Claims20
A household appliance liner, comprising:
- a first polymeric capping layer comprising a first pigment additive;
- and
- a polymeric base layer coupled to the first polymeric capping layer, the polymeric base layer comprising:
- one or more polymers;
- a second pigment additive;
- and
- a natural fiber, the natural fiber being present at a concentration of at least 50% by weight of the polymeric base layer.
A household appliance liner, comprising:
- a first polymeric capping layer comprising:
- a first pigment additive, wherein the first pigment additive is present at a concentration of about 5% to about 30% by weight of the first polymeric capping layer;
- and
- a first polymeric capping layer precursor at a concentration of about 70% to about 95% by weight of the first polymeric capping layer;
- and
- a polymeric base layer coupled to the first polymeric capping layer, the polymeric base layer comprising:
- one or more polymers;
- a second pigment additive, wherein the second pigment additive is present in the polymeric base layer at a concentration of about 1% to about 30% by weight of the polymeric base layer;
- and
- a natural fiber, the natural fiber being present at a concentration of at least 50% by weight of the polymeric base layer.
A method of making a liner for a household appliance, the method comprising:
- mixing a first polymeric capping layer precursor and a first pigment additive to form a first polymeric capping layer, wherein the first pigment additive is present at a concentration of about 5% to about 30% by weight of the first polymeric capping layer;
- mixing one or more polymers, a second pigment additive, and a natural fiber to form a polymeric base resin;
- extruding the polymeric base resin to form a polymeric base layer at a base layer formation temperature, wherein the second pigment additive is present in the polymeric base layer at a concentration of about 1% to about 30% by weight of the polymeric base layer, and wherein the natural fiber is present at a concentration of at least 50% by weight of the polymeric base layer;
- and
- laminating the polymeric base layer and the first polymeric capping layer to form the liner at about the base layer formation temperature.
