Latest Patents
One of his latest patents is for a cavity-containing polyester film and the method for producing it. This innovative film includes a layer (layer A) that contains cavities, along with layers (layers B) that consist of a polyester resin containing inorganic particles. These layers are laminated over both surfaces of layer A. The composition of layer A includes both a polyester resin and a polypropylene resin. The polypropylene resin meets specific requirements, including a melt flow rate (MFR) ranging from 1.0 to 10 g/10-minutes at a temperature of 230° C. under a load of 2.16 kg. Additionally, the deflection temperature is 85° C. or higher under load, and the weight-average molecular weight Mw ranges from 200,000 to 450,000, as measured by gel permeation chromatography (GPC). The molecular weight distribution is represented as the ratio of the weight-average molecular weight Mw to the number-average molecular weight Mn of the polypropylene resin.
