Title: Innovations by Raymond V Wass

Introduction

Raymond V Wass is a notable inventor based in Glen Ellyn, Illinois. He has made significant contributions to the field of packaging materials, particularly through his innovative patents. With a total of two patents to his name, Wass has focused on enhancing the properties of materials used in packaging.

Latest Patents

Wass's latest patents include compositions for copolyamide active-passive oxygen barrier resins. These compositions are designed to scavenge oxygen and comprise copolyamides with over 50 weight percent polyamide segments. The polyamide segments are derived from common bottling and packaging materials, such as polyhexamethyleneadipamide and polyphthalamides. The copolymers are formed through transesterification during reactive extrusion and typically contain about 0.5 to 12 weight percent of polyolefin oligomer segments. These copolyamides provide enhanced oxygen barrier properties compared to similar polyester and polyamide constructions when used in laminar structures. In preferred embodiments, multi-layered bottles made with these oxygen scavenging copolyamides consist of about 99.8 weight percent polyamide and are suitable for recycling with other polyamide bottles.

Another significant patent by Wass involves active oxygen scavenger compositions and their application in packaging articles. These compositions are all plastic materials and are typically used as at least one layer in multi-layered packaging articles such as bottles, cans, or films. The compositions often include added transition metal catalysts to enhance oxygen uptake. The use of these compositions in packaging constructions helps to extend the shelf life of oxygen-sensitive substances and reduces the need for refrigeration.
