Title: Megumi Komiyama: Innovator in Polyester Film Technology
Introduction
Megumi Komiyama is a prominent inventor based in Tokyo, Japan. She has made significant contributions to the field of polyester film technology, holding a total of 4 patents. Her innovative work focuses on developing materials that enhance the performance and quality of stencil printing.
Latest Patents
Among her latest patents is a polyester film comprising a mixture of polyesters designed for high heat applications. This heat-sensitive original sheet for stencil printing is made of a laminate of a paper sheet and a biaxially oriented polyester film. The film has a melting point ranging from 150°C to 240°C, a thickness of 0.2 to 3 μm, and an average refractive index of 1.570 to 1.578. It exhibits a thermal shrinkage stress of 100 to 800 g/mm² after being treated at 80°C for 10 seconds, and a thermal shrinkage factor of 5 to 50% after being treated at 80°C for 10 minutes. Additionally, it maintains a shrinkage factor of 15% or less after being treated in toluene at 25°C for 10 minutes. This original sheet excels in perforation sensitivity, resistance to curling, and the resolution and image density of printed images. Another notable patent is a film for high heat-sensitive stencil paper, which comprises a biaxially oriented film with a thickness of 0.5 to 6.0 μm. This film is formed from a polyester composition that includes polybutylene terephthalate and another polyester, with the polybutylene terephthalate making up 20 to 80 wt% of the total polyester.
