| titleOfInvention | Heat-shrinkable polyester film |
| abstract | [Problem] To provide a heat-shrinkable polyester film that, even while containing a PET bottle recycled material, has sufficient shrinkability, low shrinkage stress, and high solvent adhesive strength. [Solution] This heat-shrinkable polyester film contains 5-50 mass% of a PET bottle recycled material, is formed of a polyester containing an isophthalate component, and is characterized by satisfying requirements (1)-(5). (1) The shrinkage percentage in the main shrinkage direction of the film when being immersed in 98°C-hot water for 10 seconds is 50% or more. (2) The maximum shrinkage stress in the main shrinkage direction of the film as measured in 90°C-heated air is 3-15 MPa. (3) The melting calorie ΔHm of a sample, obtained by temporarily melting the film and rapidly cooling same, is 0-32 J/g when measured using a differential scanning calorimeter (DSC). (4) The solvent adhesive strength of the film when 1,3-dioxolane is used as an adhesion solvent is 2.9 N/15 mm or more. (5) The limiting viscosity of the film is 0.59-0.75 dl/g. |
