| titleOfInvention | Copolyester slice and preparation method thereof, polyester film and application thereof |
| abstract | The invention belongs to the technical field of heat shrinkable films, and particularly relates to a copolyester slice and a preparation method thereof, a polyester film and application thereof. The copolyester chip is mainly prepared from the following raw materials: acids, alcohols, catalysts, antioxidants, dyes and stabilizers; wherein the acid is terephthalic acid, the alcohol comprises ethylene glycol, neopentyl glycol and isosorbide, and the molar ratio of terephthalic acid to ethylene glycol to neopentyl glycol to isosorbide is 1: 0.78-1.3:0.24-0.4: 0.18-0.3; the mass content of the catalyst accounts for 275-1250ppm of the mass of the acid; the mass content of the antioxidant accounts for 300-1500ppm of the mass of the acid; the mass content of the dye accounts for 1-9ppm of the mass of the acid; the mass content of the stabilizer accounts for 200-600ppm of the mass of the acid. The copolyester slices are prepared through esterification and polycondensation, and then the copolyester slices are utilized to prepare the polyester film, the polyester film has an initial shrinkage temperature higher than 65 ℃ and a maximum shrinkage rate higher than 80%, and when the polyester film is manufactured into a label packaging container, the label can be prevented from further deformation and shrinkage. |
