Abstract:
The curved cleaning element is made by providing a cleaning material with a back surface and a working surface that together define a volume and thickness. A portion of the cleaning material is removed at a pivot zone. The pivot zone separates the cleaning material into a first portion and second portion. At the pivot zone, the cleaning material has less thickness and/or less volume as compared to either the first or second portions. In one embodiment, the back surface of the first portion of the cleaning material is attached to a support and the second portion of the cleaning material is pivoted at the pivot zone. The second portion of the cleaning material is secured to either the support or the first portion of the cleaning material to form a continuously curving working surface of the cleaning material.
Abstract:
The present application relates to compostable articles and compositions including at least one biodegradable polymer and a hydrophobic agent. In some embodiments, the compostable articles and compositions include a second biodegradable polymer, different from the first biodegradable polymer. In some embodiments, the first biodegradable polymer is selected from the group consisting of polyethylene succinate) (PES), poly(trimethylene succinate) (PTS), poly(butylene succinate) (PBS), poly(butylene succinate co-butylene adipate) (PBS A), poly (butylene adipate co-terephthalate) (PBAT), poly(tetramethylene adipate-co-terephthalate) (PTAT), and thermoplastic starch. In some embodiments, the presently described articles include packaging.
Abstract:
Sheet article comprising a first wall, second wall, and porous scrim between the first and second walls, and at least one seal portion sealing the first wall, second wall, and porous scrim together, as well as packaging articles and constructions comprising the same, and methods of making and using the foregoing sheet articles, packaging articles, and constructions.
Abstract:
A rotary acoustic horn. The rotary acoustic horn includes a shaft having an axial input end and an axial output end; and at least one welding portion; wherein the welding portion comprises an outer weld face that expands and contracts with the application of acoustic energy; wherein the welding portion comprises a first opposing end portion and a second opposing end portion; wherein the welding portion comprises through holes extending substantially along an axial direction of the welding portion from the first opposing end portion to the second opposing end portion; and wherein the through holes are located between the weld face and the shaft.
