PLASTIC FORMULATIONS FOR PLATELET STORAGE CONTAINERS AND THE LIKE

摘要

The invention provides a flexible plastic formulation capable of being RF sealed, extruded, cast or blow-molded, gas, steam and radiation sterilized. The plastic formulation of the invention comprises: a) from about 40 to about 90 percent by weight of a polyolefin polypropylene based material; b) from about 3 to about 25 percent by weight of a functionialized block copolymer, the functionalized block copolymer consisting essentially of a central block copolymer molecule including generally equal proportions of ethylene and butylene units, and terminal blocks of polystyrene; and c) from about 3 to about 20 percent by weight a nylon. The plastic formulations of the invention are useful in the manufacture of blood bags, tubing and the like.
