Title: The Innovative Contributions of Takashi Yamashita

Introduction

Takashi Yamashita is a notable inventor based in Yokkaichi, Japan. He has made significant contributions to the field of materials science, particularly in the development of advanced laminates and adhesive technologies. With a total of five patents to his name, Yamashita's work has had a considerable impact on packaging and adhesive applications.

Latest Patents

One of Yamashita's latest patents focuses on laminates. These laminates are prepared by laminating a base material and a sandwich base material via a bonding layer. The adhesion strength between the sandwich base material and bonding layer is not less than 200 g/15 mm wide at 23 °C. The bonding layer is formed of a resin composition that comprises an ethylene/α-olefin copolymer resin. This innovation provides useful laminates that exhibit excellent adhesion properties to metal foil, deposited metal surfaces of metal-deposited films, and surfaces of other sandwich base materials. Additionally, these laminates possess low smell and high strength, making them ideal for packaging films.

Another significant patent by Yamashita is for a pressure-sensitive adhesive tape. This tape is a laminate made up of a woven fabric layer whose warp and weft are thermoplastic-resin-made flat yarns. It also includes a layer of polyethylene with a specific density and melt flow rate, laminated to one or both surfaces of the woven fabric layer. A pressure-sensitive adhesive layer is then laminated to the polyethylene layer, fulfilling specific performance criteria.
