Heat-sterilizable polyolefin compositions and articles manufactured therefrom

A sterilizable parenteral solution bag assembly comprising

• an inner sealed plastic film bag containing a parenteral solution;
• an outer sealed bag enclosing the inner bag, said outer bag having a width and a length from about 0.25 to about 1.5 inches larger than the corresponding dimensions of the inner bag;
• the outer film bag resin comprising a blend of:
• (a) from about 10 to about 60 wt % of a random copolymer of from about 1 to about 6 wt % ethylene and of from about 94 to about 99 wt % propylene;
• (b) from about 40 to about 90 wt % of a linear low density polyethylene produced by copolymerization of ethylene with at least one C.sub.4 -C.sub.18 alpha-olefin comonomer and having a density between about 0.915 and about 0.940 gm/cc,
• in the space between the outer and inner bags a quantity of a substance sufficient to control removal of a component from or to control the addition of a component to the parenteral solution through the inner bag film wall.
