Introduction

David B Ramsey is an accomplished inventor based in Angleton, TX (US). He holds a total of 5 patents that showcase his expertise in developing advanced materials, particularly in the field of stretch films. His innovative contributions have significantly impacted the industry, particularly in enhancing the performance of packaging materials.

Latest Patents

One of his notable patents is for films with superior impact resistance and improved catastrophic failure resistance under high strain rate. These stretch films are designed to exhibit good puncture and impact resistance while also resisting defect propagation. The films have an ultimate stretch of at least 200 percent, a dart impact strength of at least about 700 gms/mil, and a catastrophic failure stretch of at least 95 percent of the elongation to break value. The preferred composition includes at least three layers and at least 50 percent by weight of polyethylene polymers. Another significant patent is for a multilayer thermoplastic stretch wrap film that possesses substantial one-sided cling properties. This film is made without using polymers with high levels of n-hexane extractables, dissimilar polymer chemistries, or low molecular weight tackifiers. The cling layer comprises a homogeneously branched ethylene polymer composition, while the non-cling layer consists of a propylene or ethylene polymer composition. This multilayer film is particularly useful for load palletization end-use applications.
