Latest Patents
Inoue's latest patents include a heat-shrinkable polyester film that exhibits exceptional properties. This film demonstrates a hot-water heat shrinkage of 40% or more when immersed in hot water at 98° C for 10 seconds. It features a planar orientation coefficient ranging from 0.035 to 0.070 and primarily consists of ethylene terephthalate with 6-25 mol % diethylene glycol in the polyester resin. Additionally, the film has a maximum shrinkage stress of 2-17 MPa when measured in hot air at 90° C and a tensile elongation at break of 20% or more in a direction orthogonal to the main shrinkage direction after aging in a specific atmosphere.
Another notable invention is the film roll of heat-shrinkable polyester, which is produced by winding the heat-shrinkable polyester film on a paper tube. This roll has a primary shrinkage in the longitudinal direction and a shrinkage rate of 40% or more. The film roll features a winding length between 1,000 to 30,000 meters, a width of 50 to 1,500 mm, and a thickness of 5-30 μm. The thickness irregularity in the width direction is maintained at 20% or less, ensuring high quality and consistency.
