Title: The Innovations of Yozo Ohba
Introduction
Yozo Ohba is a notable inventor based in Ibaraki, Japan. He has made significant contributions to the field of synthetic materials, particularly in the development of innovative papers and labels. With a total of 4 patents to his name, Ohba's work has had a considerable impact on various industries.
Latest Patents
One of his latest patents is for a synthetic paper designed for writing and printing. This pencil writable and printable synthetic paper comprises a finely porous polyolefin film layer with an opacity of at least 80%. The film is obtained by stretching a polyolefin film that contains between 8 to 65% by weight of an inorganic fine powder. This innovative design includes a stretched ethylene-vinyl alcohol copolymer film layer, which prevents hydrocarbon solvents in printing inks from penetrating the polyolefin film layer, thus eliminating local surface unevenness and curling.
Another significant patent is a process for producing synthetic label paper. This process involves preparing a multi-layer film made from a thermoplastic resin containing an inorganic fine powder. The back side of this film has a layer of a heat-sealable resin with a lower melting point. The embossed multi-layer film is then stretched at a specific temperature range. This label paper, when used for in-mold decorating of containers, provides a blister-free appearance and maintains the integrity of the container without deformation.
