Title: Innovations of Shigeru Nedzu

Introduction

Shigeru Nedzu is a prominent inventor based in Shizuoka, Japan. He has made significant contributions to the field of materials science, particularly in the development of advanced resin compositions and injection molding techniques. With a total of 10 patents to his name, Nedzu continues to push the boundaries of innovation in his industry.

Latest Patents

One of his latest patents is for a bag having excellent blocking resistance. This invention involves bags formed from a film composed of a resin blend of polyethylene (PE) and polybutylene terephthalate (PBT) resin. The film is designed with a multi-layer structure created through coextrusion inflation molding techniques, featuring inner and outer layers that are laminated together. The inner layer is made of a polyolefin, while the outer layer consists of a PE/PBT blend, with PBT present in an amount of 5 to 30 wt. % based on the total weight of the resin composition. The thickness ratio of the internal layer to the external layer is ideally between 95/5 to 30/70.

Another notable patent focuses on improving injection molded articles with three-dimensional patterns. This process involves placing a master film of a thermoplastic resin with a three-dimensional master pattern into a mold. An injection-moldable resin is then injected into the mold cavity, allowing the surface region of the resin to conform to the master pattern. The master film is subsequently removed, revealing the three-dimensional pattern on the injection molded resin.
