Latest Patents

One of his latest patents is for a lightweight multilayer foam film with enhanced perceived surface whiteness. This innovative film is designed for light-blocking, signage, and general packaging applications. It features a bulk density of less than 0.962 gr/cm, with more than 50% of the cells in the foam layer being closed cells. The film has a thickness greater than 1 mil, and one of the solid skin layers contains white pigment. Additionally, the white skin layer has a skin whiteness value of greater than 80 according to ASTM E313-73, and a skin layer tint value of less than 1 according to the same standard. The lightness value (L*) of the white skin layer exceeds 90 in the CIE L*a*b* dimension according to ASTM E308. Furthermore, the film boasts a very smooth surface with a smoothness value of less than 25 in Sheffield smoothness unit configuration according to TAPPI T 538.

Another notable patent involves a method of making a flat foam sheet comprising recycled PET and the resulting product. This method utilizes a co-extrusion system with at least two single screw extruders. It incorporates a low intrinsic viscosity (I.V.) polyester feedstock made from up to 100% recycled polyester flakes. The process includes introducing a supercritical physical blowing agent into the melted polyester feedstock, allowing for the creation of a multilayer foam sheet suitable for various packaging applications.
