Abstract: The present invention provides an improved coextruded medical port tubing. The medical port tubing provides characteristics that are desirable in the medical industry and therefore can be used as a medical port tubing in, for example, renal therapy or blood donor tubes. To this end, the present invention provides a coextruded medical grade port tubing comprising: an outer layer comprising a blend of polypropylene copolymer and styrene-ethylene-butylene-styrene copolymer; a tie layer; and a core layer comprising polyvinyl chloride.
