Mark S. Lee, a distinguished inventor based in North Kingstown, RI, holds an impressive portfolio of 18 patents. His innovative work primarily focuses on the development and enhancement of biaxially oriented polylactic acid (BOPLA) films, contributing significantly to advancements in biodegradable packaging materials.

Latest Patents

Among his latest inventions, Lee has patented a novel **Biaxially Oriented Cavitated Polylactic Acid Film**. This laminate film features a core layer made from a blend of crystalline polylactic acid polymer and a metal salt phosphorus-containing compound nucleating agent. The film is biaxially oriented at low transverse direction orientation temperatures, resulting in a distinctive white opaque cavitated appearance. This innovation not only reduces film density but also enhances mechanical properties. Furthermore, the laminate film may include additional layers such as a heat sealable layer of amorphous polylactic acid resin, offering versatility in its applications.

Another notable patent is the **Biaxially Oriented Polylactic Acid Film with Reduced Noise Level and Improved Moisture Barrier**. This formulation of metallized BOPLA films provides a softer feel and quieter sound while maintaining film making stability. Lee's research reveals that these films exhibit significantly improved moisture barrier properties compared to traditional metallized BOPLA films, making them suitable for various packaging applications. Remarkably, the films can achieve moisture barrier levels of 2.0 g/m/day or less at 38°C and 90% relative humidity, all while preserving their bio-compostability.
