POLYESTER BOTTLE FOR DRINK

摘要

PURPOSE: A polyester bottle is provided which has improved storage period of soda water containing fruit juice. CONSTITUTION: As blow-molding copolymer of polyethyleneterephthalate and polyethylenenaphthalate having 0.65-0.95dL/g of an inherent viscosity is excellent in transparency at the same time as screening the ultraviolet rays having 370 nm or less and oxygen which is protected from changing in quality of filling a bottle. The process cost of that is cheap as simplifying the process. The copolymer of polyethyleneterephthalate and polyethylenenaphthalate is possible hot-fill at 95°C, the photo-permeability transmittancy of the copolymer is 85-92%, the haze value of that is 1.0-2.0 %.
