Title: Innovator Donald A. Schultz: Pioneering Advances in Gas-Permeable Membranes
Introduction
Donald A. Schultz is an accomplished inventor based in San Mateo, California, known for his significant contributions to the field of materials science. With a remarkable portfolio of five patents, Schultz has been instrumental in developing innovative solutions that enhance the packaging of fresh produce, among other applications.
Latest Patents
Schultz's latest inventions include groundbreaking advances in gas-permeable membranes, specifically designed for the effective packaging of fresh-cut fruits and vegetables as well as other respiring biological materials. These membranes boast an operability rating of at least 775,000 ml/m.atm.24 hrs and a permeability ratio of at least 1.3. Notably, the ratio of copermability to operability (R) is at least 1.5, showcasing their potential in prolonging product freshness. These membranes are produced by forming thin polymeric coatings on microporous polymeric films, with preferred coating materials being side chain crystalline polymers, and the microporous films often contain inorganic fillers, particularly from ultrahigh molecular weight polyethylene or polypropylene.
Another innovative patent includes the development of polymeric modifying agents that feature a sharply-melting crystalline polymer ingredient and an active chemical component. These agents are particularly beneficial as they remain dormant at low temperatures and only modify the matrix upon reaching a specified crystalline melting point. This allows for stored stable compositions, which can transform into crosslinked resins when exposed to heat and light.
