Abstract
The present invention provides a polyester resin composition comprising (A) 10 to 90% by weight of a polyethylene terephthalate polymer having 100 to 75 mole % of ethylene terephthalate units and (B) 90 to 10% by weight of a polyester resin wherein the polyester resin composition when molded into a sheet has an oxygen permeability coefficient of 3.0 or less cc-mm/m,day·atm. The polyester resin composition of the present invention gives a molded product which is outstanding in transparency, gas barrier property, ultraviolet-screening property and impact strength and therefore suitable as a reduced pressure blood-collecting tube.
