Title: Dennis E Kester: Innovator in Packaging Technology

Introduction

Dennis E Kester is a notable inventor based in Neenah, WI (US). He has made significant contributions to the field of packaging technology, holding a total of 5 patents. His work focuses on improving packaging structures, particularly in sterile environments.

Latest Patents

One of his latest inventions is the Retortable foil-based packaging structure. This invention provides improved films and pouches for use in sterile packaging, ensuring that both the package and product are sterilized after filling and sealing. The films are a family of foil-based, multiple layer structures that incorporate an enhanced combination of layers forming the sealant layer and adhesive bonding to the foil layer. The sealant layer consists of linear low-density polyethylene, while the adjacent layer is a blend of 20% to 80% propylene ethylene copolymer and 80% to 20% linear low-density polyethylene. The foil layer is primed with an anhydride modified propylene-based primer, and additional layers of propylene-based polymers may be used.

Another significant invention is the Retortable packaging structure, which is made entirely with polymeric materials. This improved heat sealable structure features an inner heat seal layer of linear low-density polyethylene. The second layer is also linear low-density polyethylene, with an optional blend of 0% to 80% medium density polyethylene. The third layer consists of anhydride modified medium density polyethylene, followed by layers of nylon, ethylene vinyl alcohol, and nylon. An optional layer can be included between the second and third layers, comprising at least 20% linear low-density polyethylene and up to 80% medium density polyethylene. The entire multiple layer structure is firmly adhered together, ensuring mutual support among the layers in the unitary package.
