Title: Innovations by Nao Yokota: Pioneering Biaxially Oriented Polylactic Acid Films
Introduction
Nao Yokota is an accomplished inventor based in Saunderstown, Rhode Island, with an impressive portfolio of 12 patents to her name. Her work primarily focuses on enhancing the properties of polylactic acid films, contributing significantly to the field of sustainable materials and packaging solutions.
Latest Patents
Among her latest innovations, Nao Yokota has developed a groundbreaking biaxially oriented cavitated polylactic acid film. This film features a core layer that includes a blend of crystalline polylactic acid polymer and a metal salt phosphorus-containing compound nucleating agent. The unique fabrication process allows the film to achieve a degree of cavitation around the metal salt, resulting in a white opaque appearance with a lower density and improved mechanical properties. Additionally, this laminate film can incorporate various layers, such as a heat sealable layer made of amorphous polylactic acid resin, further optimizing its application in flexible packaging.
Another notable invention by Yokota is the metallized biaxially oriented polylactic acid (BOPLA) film that boasts reduced noise levels and an improved moisture barrier. The formulation gives the film a softer touch and quieter sound, while maintaining stability during production. Impressively, these films exhibit enhanced moisture barrier properties, measuring 2.0 g/m/day or less at 38°C and 90% relative humidity, making them ideal for packaging applications that prioritize both performance and compostability.
